Operating from a single 5V supply, the LTC2389-18 supports pinconfigurable fully differential (±4.096V), pseudo-differential unipolar (0V to 4.096V), and pseudo-differential bipolar (±2.048V) analog input ranges, allowing it to interface with multiple signal chain formats without requiring additional level translation or signal conditioning.
The LTC2389-18 achieves ±3LSB INL (maximum), no missing codes at 18-bits, and 99.8dB (fully differential)/ 95.2dB (pseudo differential) SNR (typical).
