DESCRIPTION
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 AVDD and 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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
