Operating from a single 5V supply, the LTC2372-16 has a highly configurable, low crosstalk 8-channel input multiplexer, supporting fully differential, pseudo-differential unipolar and pseudo-differential bipolar analog input ranges. The LTC2372-16 achieves ±1LSB INL (maximum) in all input ranges, no missing codes at 16-bits and 96dB (fully differential)/93.5dB (pseudo-differential) SNR (typical). The LTC2372-16 has an onbo...
