ADS7861 - Dual, 500kHz, 12-Bit, 2+2 Ch, Simultaneous Sampling Analog-To-Digital Converter

The ADS7861 is a dual, 12-bit, 500kHz, 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 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 both an SSOP-24 and a QFN-32 package and is fully specified over the -40°C to +125°C operating range.
