DESCRIPTION
The ADS8361 is a dual, 16-bit, 500kSPS, Analog-to-Digital
(A/D) converter with four fully differential input channels grouped
into two pairs for high-speed, simultaneous signal acquisition.
Inputs to the sample-and-hold amplifiers are fully differential
and are maintained differentially to the input of the A/D con-
verter. This provides excellent common-mode rejection of
80dB at 50kHz, which is important in high-noise environments.
The ADS8361 offers a high-speed, dual serial interface and
control inputs to minimize software overhead. The output data
for each channel is available as a 16-bit word. The ADS8361
is offered in SSOP-24 and QFN-32 (5x5) packages and is fully
specified over the –40°C to +125°C operating range.
