3 Description

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 powerdown

features. The device also includes data storage

up to four conversion results per channel.
