When operatingwith a single supply, short VSS to GND.Op-Amp Configurations The IC is a single-supply dual op amp ideal for differential sensing, noninverting amplification, buffering, and filter-ing. A few common configurations are shown in the next few sections.The following sections explain how to configure one of the device’s op amps (op-amp A). To configure the device’s second op amp (op-amp B), the same equations can be used after modifying the component reference designa-tors. For op-amp B, the equations should be modified by adding 10 to the number portion of the reference designa-tors (e.g., for the noninverting configuration, equation R1 becomes R11 and R5 becomes R15).Noninverting ConfigurationThe EV kit comes preconfigured as a noninvertingamplifier. The gain is set by the ratio of R5 and R1. TheEV kit comes preconfigured for a gain of +11. The outputvoltage for the noninverting configuration is given by the equation below:OUTA INAP R5V 1V R1 =+ *Default position.JUMPERSHUNT POSITION DESCRIPTION JU1Installed*Connects INAM to R1. Also shorts capacitor C5.OpenConnects INAM to R1 through capacitor C5. When AC-coupling is desired, remove the shunt and install capacitor C5. JU2Installed*Connects INAP to JU3 position 1. Also shorts capacitor C6. OpenConnects INAP to JU3 position 1 through capacitor C6. When AC-coupling is desired, remove the shunt and install capacitor C6.

When AC-coupling is desired, remove the shunt and install capacitor C15. JU6Installed*Connects INBP to JU6 position 1. Also shorts capacitor C16. OpenConnects INBP to JU6 position 1 through capacitor C16. When AC-coupling is desired, remove the shunt and install capacitor C16. JU71-2*Connects INBP to JU7 and C16 through R12 and R182-3Connects INBP to GND through R12 and R18JU8Installed*Connects OUTB to OUTB Open Connects OUTB to OUTB through capacitor C20. When AC-coupling is desired, remove the shunt and install capacitor C20.R1–R3, and R5 with appropriate resistors. WhenR1 = R2 and R3 = R5, the CMRR of the differential ampli-fier is determined by the matching of the resistor ratiosR1/R2 and R3/R5.OUTA INAP INAM V GAIN (V V )=−where:R5R3GAIN R1R2==Sallen-Key Filter ConfigurationThe Sallen-Key filter topology is ideal for filtering sensorsignals with a second-order filter and acting as a buffer.Schematic complexity is reduced by combining the filterand buffer operations. The EV kit can be configured ina Sallen-Key topology by replacing and populating afew components. The Sallen-Key topology is typicallyconfigured as a unity-gain buffer, which can be done byreplacing R1 and R5 with 0Ω resistors and short JU2. Thenoninverting signal is applied to the INAP test point withJU2 short and short pins 1-2 on JU3 or do the same on theINBP pad similarly. The filter component pads are R2–R4,and R8, where some have to be populated with resistorsand others with capacitors.Lowpass Sallen-Key FilterTo configure the Sallen-Key as a lowpass filter, populatethe R2 and R8 pads with resistors, and populate the R3and R4 pads with capacitors. The corner frequency and Qare then given by:C R3R2R8f Q ==the R3 and R4 pads with resistors and populate the R2 and R8 pads with capacitors. The corner frequency and Qare then given by:C R4R2R8f Q ==Transimpedance Application To configure op-amp U1-A as a transimpedance amplifier (TIA), replace R1 with a 0Ω resistor and install a shunt on jumper JU1 and shunt on pins 2-3 on jumper JU3. The output voltage of the TIA is the input current multiplied by the feedback resistor:OUT IN BIAS OS V (I I )R4V =+×+where R4 is installed as a 10kΩ resistor, I IN is defined as the input current source applied at the INAM pad, I BIAS is the input bias current, and V OS is the input offset voltage of the op amp. Use capacitor C8 (and C7, if applicable) to stabilize the op amp by rolling off high-frequency gain due to a large cable capacitance. Similarly, we can configure op-amp U1-B for transimpedance application.Capacitive Loads Some applications require driving large capacitive loads. To improve the stability of the amplifier, replace R6 (R16 for U1-B) with a suitable resistor value to improve ampli-fier phase margin. The R6/C9 (R16/C19 for U1-B) filter can also be used as an anti-alias filter, or to limit amplifier output noise by reducing its output bandwidth.DESIGNATION QTY DESCRIPTIONC1, C320.1µF ±10%, 25V X7R ceramic capacitors (0805)C2, C424.7µF ±10%, 25V X5R ceramic capacitors (0805)C5–C10, C15–C200Not installed, ceramic capacitors(0805)GND2Black test points INAM, INAP,INBM, INBP,OUTA, OUTB,VDD, VSS8Red test pointsJU1, JU2,JU4–JU6, JU862-pin headers JU3, JU723-pin headers DESIGNATION QTY DESCRIPTION R1, R2,R11, R1241kΩ ±1% resistors (0805)R3, R4, R7,R13, R14, R170Not installed, resistors (0805) R5, R15210kΩ ±1% resistors (0805)R6, R8,R16, R1840Ω ±5% resistors (0805) TP1, TP20Not installed, miniature test points U11Dual low-power, rail-to-rail I/O opamp (8 µMAX)Maxim MAX44242AUA+—8Shunts—1PCB: MAX44242 EVKITFigure 1.

The small footprints of the GS321 family packages save space on printed circuit boards and enable the design of smaller electronic products.Power Supply Bypassing and Board LayoutGS321 family series operates from a single 2.1V to 5.5V supply or dual ±1.05V to ±2.75V supplies. For best performance, a 0.1µF ceramic capacitor should be placed close to the V DD pin in single supply operation. For dual supply operation, both V DD and V SS supplies should be bypassed to ground with separate 0.1µF ceramic capacitors.Low Supply CurrentThe low supply current (typical 40uA per channel) of GS321 family will help to maximize battery life. They are ideal for battery powered systemsOperating VoltageGS321 family operates under wide input supply voltage (2.1V to 5.5V). In addition, all temperature specifications apply from -40 o C to +125 o C. Most behavior remains unchanged throughout the full operating voltage range. These guarantees ensure operation throughout the single Li-Ion battery lifetimeRail-to-Rail InputThe input common-mode range of GS321 family extends 100mV beyond the supply rails (V SS-0.1V to V DD+0.1V). This is achieved by using complementary input stage. For normal operation, inputs should be limited to this range.Rail-to-Rail OutputRail-to-Rail output swing provides maximum possible dynamic range at the output. This is particularly important when operating in low supply voltages. The output voltage of GS321 family can typically swing to less than 5mV from supply rail in light resistive loads (>100kΩ), and 30mV of supply rail in moderate resistive loads (10kΩ).Capacitive Load ToleranceThe GS321 family is optimized for bandwidth and speed, not for driving capacitive loads. Output capacitance will create apole in the amplifier’s feedback path, leading to excessive peaking and potential oscillation. If dealing with load capacitance isa requirement of the application, the two strategies to consider are (1) using a small resistor in series with the amplifier’s output and the load capacitance and (2) reducing the bandwidth of the amplifier’s feedback loop by increasing the overall noise gain. Figure 2. shows a unity gain follower using the series resistor strategy. The resistor isolates the output from the capacitanceFigure 2. Indirectly Driving a Capacitive Load Using Isolation ResistorThe bigger the R ISO resistor value, the more stable V OUT will be. However, if there is a resistive load R L in parallel with the capacitive load, a voltage divider (proportional to R ISO/R L) is formed, this will result in a gain error.The circuit in Figure 3 is an improvement to the one in Figure 2. R F provides the DC accuracy by feed-forward the V IN to R L. C Fand R ISO serve to counteract the loss of phase margin by feeding the high frequency component of the output signal back to the amplifier’s inverting input, thereby preserving the phase margin in the overall feedback loop. Capacitive drive can be increased by increasing the value of C F. This in turn will slow down the pulse response.Figure 3. Indirectly Driving a Capacitive Load with DC AccuracyTypical Application CircuitsDifferential amplifierThe differential amplifier allows the subtraction of two input voltages or cancellation of a signal common the two inputs. It is useful as a computational amplifier in making a differential to single-end conversion or in rejecting a common mode signal.
