DESCRIPTION
The ADS7832 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.
The 5V single-supply requirements and standard CS,
RD, and WR control signals make the part easy to use
in microprocessor applications. Conversion results are
available in two bytes through an 8-bit three-state
output bus.
The ADS7832 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.
