DESCRIPTION

The ADS7861 is a dual, 12-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 differential to the input of the

A/D converter. This provides excellent common-mode rejec-

tion of 80dB at 50kHz which is important in high noise

environments.

The ADS7861 offers a high-speed, dual serial interface and

control inputs to minimize software overhead. The output data

for each channel is available as a 12-bit word. The ADS7861

is offered in both an SSOP-24 and a QFN-32 package and is

fully specified over the –40°C to +125°C operating range.
