Description

General part information

ADS7863A Series

The ADS7863A is a dual, 12-bit, 2-MSPS, analog-to-digital converter (ADC) with four fully-differential or six pseudo-differential input channels grouped into two pairs for high-speed, simultaneous signal acquisition. Inputs to the sample-and-hold (S/H) amplifiers are fully differential and are maintained differential to the ADC input. This architecture provides excellent common-mode rejection of 72 dB at 100 kHz, which is a critical performance characteristic in noisy environments.

The device is pin-compatible with the ADS7861, but offers additional features such as a programmable reference output, flexible supply voltage (2.7 V to 5.5 V for AVDDand BVDD), a pseudo-differential input multiplexer with three channels per ADC, and several power-down features.

The device is offered in an SSOP-24 and a 4-mm × 4-mm QFN-24 package. The device is specified over the extended operating temperature range of –40°C to +125°C.
