EVM Overview
The ADS7861 and ADS8361 are high-speed, low-power, 12-bit and 16-bit A/D
converters that operate from independent 5-V AV
DD
and 5-V D
VDD
(2.7-V to
3.6-V DV
DD
for ADS8361) supplies.
The four fully differential analog inputs are divided into two pairs (A and B). The
ADS7861 and ADS8361 accept an analog input voltage in the range of –VREF
to +VREF (5 V
p–p
), centered on the internal 2.5-V reference. The part also ac-
cepts bipolar input ranges when a level shift circuit is used in the analog front-
end circuitry. Refer to Section 12 of Op Amps for Everyone (literature number
SLOD006) for information on various circuit applications.
