DESCRIPTION
The ADS7864 is a dual 12-bit, 500kHz Analog-to-
Digital (A/D) converter with 6 fully differential input
channels grouped into three pairs for high speed simul-
taneous signal acquisition. Inputs to the sample-and-
hold amplifiers are fully differential and are main-
tained 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 ADS7864 offers a parallel interface and control
inputs to minimize software overhead. The output data
for each channel is available as a 16-bit word (address
and data). The ADS7864 is offered in a TQFP-48
package and is fully specified over the –40
°
C to +85
°
C
operating range.
