Operating from a single 3.3V or 5V supply, the LTC2320‑12 has an 8VP-P differential input range, making it ideal for applications which require a wide dynamic range with high common mode rejection. The LTC2320-12 achieves ±0.25LSB INL typical, no missing codes at 12 bits and 77dB SNR. The LTC2320-12 has an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference. The LTC2320-12 also has a high speed SPI-compatible serial interface that supports CMOS or LVDS. The fast 1.5Msps per channel throughput with no latency makes the...
