DESCRIPTION
The ADC7802 is a monolithic CMOS 12-bit A/D
converter with internal sample/hold and four-channel
multiplexer. An autocalibration cycle, occurring auto-
matically at power on, guarantees a total unadjusted
error within 1/2LSB 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
very easy to use in microprocessor applications. Con-
version results are available in two bytes through an 8-
bit three-state output bus.
The ADC7802 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.
