ADC9708
6-Channel 8-Bit mP Compatible A D Converter
General Description
The ADC9708 is a single slope 8-bit 6-channel ADC sub-
system that provides all of the necessary analog functions
for a microprocessor-based data control system The device
uses an external microprocessor system to provide the nec-
essary addressing timing and counting functions and in-
cludes a 1-of-8 decoder 8-channel analog multiplexer sam-
ple and hold ramp integrator precision ramp reference and
a comparator on a single monolithic chip
