The ADC168M102R-SEP is a dual, 16-bit, 1MSPS analog-to-digital converter (ADC). This ADC has eight pseudo- or four fully differential input channels grouped into two pairs for simultaneous signal acquisition. The analog inputs are maintained differentially to the input of the ADC. Use the input multiplexer in either pseudo-differential mode or fully differential mode. Pseudo-differential mode supports up to four channels per ADC (4x2), and fully differential mode converts up to two inputs per ADC (2x2).

The ADC168M102R-SEP offers two programmable reference outputs, flexible supply voltage ranges, a programmable auto-sequencer, and several power-down features. The device also includes data storage up to four conversion results per channel.
