Operating from a single 3.3V or 5V supply, the LTC231112 has an 8VP-P differential input range, making it ideal for applications which require a wide dynamic range with high common mode rejection. The LTC2311-12 achieves ±0.25LSB INL typical, no missing codes at 12 bits and 73dB SNR typical. The LTC2311-12 has an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature compensated reference and provides an external 1.25V buffered reference input. The L...
