ADS7803
Autocalibrating, 4-Channel, 12-Bit
ANALOG-TO-DIGITAL CONVERTER
DESCRIPTION
The ADS7803 is a monolithic CMOS 12-bit analog-
to-digital converter with internal sample/hold and four-
channel multiplexer. It is designed and tested for full
dynamic performance with input signals to 50kHz. An
autocalibration cycle guarantees a total unadjusted
error within
±
3/4LSB over the specified temperature
range, eliminating the need for offset or gain adjust-
ment. The 5V single-supply requirements and stan-
dard CS, RD, and WR control signals make the part
easy to use in microprocessor applications. Conver-
sion results are available in two bytes through an 8-bit
three-state output bus.
The ADS7803 is available in a 28-pin plastic DIP and
28-lead PLCC, fully specified for operation over the
industrial –40
°
C to +85
°
C temperature range.
