Operating from a single 3.3V or 5V supply, the LTC232116 has an 8VP-P differential input range, making it ideal for applications which require a wide dynamic range with high common mode rejection. The LTC2321-16 achieves ±4LSB INL typical, no missing codes at 16 bits and 81dB SNR. The LTC2321-16 has an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference. The LTC2321-16 also has a high speed SPIcompatible serial interface that supports CMOS or LVDS. The fast 2Msps per channel throughput with no cycle latency makes...
