Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime.Note 2: The inputs are protected by back-to-back diodes and internal series resistors. If the differential input voltage exceeds 10V, the input current must be limited to less than 10mA.Note 3: A heat sink may be required to keep the junction temperature below absolute maximum ratings.Note 4: Both the LT6011C/LT6012C and LT6011I/LT6012I are guaranteed functional over the operating temperature range of –40°C to 85°C.Note 5: The LT6011C/LT6012C are guaranteed to meet the specified performance from 0°C to 70°C and is designed, characterized and expected to meet specified performance from –40°C to 85°C but is not tested or QA sampled at these temperatures. The LT6011I/LT6012I are guaranteed to meet specified performance from –40°C to 85°C.Note 6: This parameter is not 100% tested.Note 7: Matching parameters are the difference between any two amplifiers. ∆CMRR and ∆PSRR are defined as follows: (1) CMRR and PSRR are measured in µV/V for the individual amplifiers. (2) The difference between matching amplifiers is calculated in µV/V. (3) The result is converted to dB.Note 8: The specifications for V OS , I B , and I OS depend on the grade and on the package.

Temperature differentials across the input connections can generate thermocouple voltages of 10’s of microvolts so the connections to the input leads should be short, close together and away from heat dissipating components. Air currents across the board can also generate temperature differentials.The extremely low input bias currents (20pA typical) allow high accuracy to be maintained with high impedance sources and feedback resistors. The LT6011/LT6012 low input bias currents are obtained by a cancellation circuit on-chip. This causes the resulting I B + and I B – to be uncorrelated, as implied by the I OS specification being comparable to I B . Do not try to balance the input resistances in each input lead; instead keep the resistance at either input as low as possible for maximum accuracy.Leakage currents on the PC board can be higher than the input bias current. For example, 10G Ω of leakage between a 15V supply lead and an input lead will generate 1.5nA!Surround the input leads with a guard ring driven to the same potential as the input common mode to avoid exces-sive leakage in high impedance applications.Input ProtectionThe LT6011/LT6012 feature on-chip back-to-back diodes between the input devices, along with 500Ω resistors inseries with either input. This internal protection limits the input current to approximately 10mA (the maximum al-lowed) for a 10V differential input voltage. Use additional external series resistors to limit the input current to 10mA in applications where differential inputs of more than 10V are expected. For example, a 1k resistor in series with each input provides protection against 30V differential voltage.Input Common Mode RangeThe LT6011/LT6012 output is able to swing close to each power supply rail (rail-to-rail out), but the input stage is limited to operating between V – + 1V and V + – 1.2V. E xceed-ing this common mode range will cause the gain to drop to zero, however, no phase reversal will occur.Total Input NoiseThe LT6011/LT6012 amplifier contributes negligible noise to the system when driven by sensors (sources) with impedance between 20k Ω and 1M Ω. Throughout this range, total input noise is dominated by the 4kTR S noise of the source. If the source impedance is less than 20k Ω,the input voltage noise of the amplifier starts to contribute with a minimum noise of 14nV/√Hz for very low source im-pedance. If the source impedance is more than 1M Ω, the input current noise of the amplifier, multiplied by this high impedance, starts to contribute and eventually dominate.Total input noise spectral density can be calculated as:v e kTR i R n TOTAL n S n S ()()=++224APPLICATIO S I FOR ATIOWUU U 5V1112131415Information furnished by Linear Technology Corporation is believed to be accurate and reliable.However, no responsibility is assumed for its use.
