DESCRIPTION
The ADS7862 is a dual 12-bit, 500kHz analog-to-digital
converter (A/D) with 4 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 rejection of
80dB at 50kHz, which is important in high noise environments.
The ADS7862 offers parallel interface and control inputs to
minimize software overhead. The output data for each channel
is available as a 12-bit word. The ADS7862 is offered in an
TQFP-32 package and is fully specified over the –40°C to
+85°C operating range.
