Operating from a single 3.3V or 5V supply, the LTC2323-14 has an 8VP-P differential input range, making it ideal for applications which require a wide dynamic range with high common mode rejection. The LTC2323-14 achieves ±1LSB INL typical, no missing codes at 14 bits and 80dB SNR. The LTC2323-14 has an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference. The LTC2323-14 also has a high speed SPI-compatible serial interface that supports CMOS or LVDS. The fast 5Msps per channel throughput with one-cycle latency makes the LT...
