ADS7263 (ACTIVE)

14-bit 1MSPS 4x2/2x2 Simultaneous Sampling SAR ADC

 

Description

The ADS8363 is a dual, 16-bit, 1-MSPS analog-to-digital converter (ADC) with 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. The input multiplexer can be used in either pseudo-differential mode, supporting up to four channels per ADC (4x2), or in fully-differential mode that allows to convert up to two inputs per ADC (2x2). The ADS7263 is a 14-bit version and the ADS7223 is a 12-bit version of the ADS8363.

The ADS8363, ADS7263, and ADS7223 offer two programmable reference outputs, flexible supply voltage ranges, a programmable auto-sequencer, data storage of up to four conversion results per channel, and several power-down features.

All devices are offered in a 5-mm x 5-mm, 32-pin VQFN package.
