3 Description
The ADS8363 is a dual, 16-bit, 1-MSPS analog-todigital
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 pseudodifferential
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.
