ADS7861

The ADS7861 is a dual, 12-bit, 500kHz, analog-todigital converter 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 50kHzwhich 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°Coperating range.
