DESCRIPTION
The ADS7861 is a dual, 12-bit, 500kHz, analog-to-
digital converter with 4 fully differential input channels
grouped into two pairs for high speed, simultaneous
signal acquisition. Inputs to the sample-and-hold ampli-
fiers are fully differential and are maintained differen-
tial 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 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 a 24-lead SSOP
package and is fully specified over the –40°C to +85°C
operating range.
