T YPICAL APPLICATION

A PPLICATIONS

D ESCRIPTION Low Power 3V ADCs

The LTC ?2228/LTC2227/LTC2226 are 12-bit 65Msps/

40Msps/25Msps, low power 3V A/D converters designed for digitizing high frequency, wide dynamic range signals. The L TC2228/L TC2227/L TC2226 are perfect for demand-ing imaging and communications applications with AC performance that includes 71.3dB SNR and 90dB SFDR for signals at the Nyquist frequency.

DC specs include ±0.3LSB INL (typ), ±0.15LSB DNL (typ) and no missing codes over temperature. The transition noise is a low 0.25LSB RMS .

A single 3V supply allows low power operation. A separate output supply allows the outputs to drive 0.5V to 3.6V logic.

A single-ended CLK input controls converter operation. An optional clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime.

Note 2: All voltage values are with respect to ground with GND and OGND wired together (unless otherwise noted).

Note 3: When these pin voltages are taken below GND or above V DD , they will be clamped by internal diodes. This product can handle input currents of greater than 100mA below GND or above V DD without latchup.Note 4: V DD = 3V , f SAMPLE = 65MHz (L TC2228), 40MHz (L TC2227), or 25MHz (L TC2226), input range = 2V P-P with differential drive, unless otherwise noted.

Note 5: Integral nonlinearity is de? ned as the deviation of a code from a straight line passing through the actual endpoints of the transfer curve. The deviation is measured from the center of the quantization band.Note 6: Offset error is the offset voltage measured from –0.5 LSB when the output code ? ickers between 0000 0000 0000 and 1111 1111 1111.Note 7: Guaranteed by design, not subject to test.

Note 8: V DD = 3V , f SAMPLE = 65MHz (L TC2228), 40MHz (L TC2227), or 25MHz (L TC2226), input range = 1V P-P with differential drive.Note 9: Recommend operating conditions.
