ADC0811 8-Bit Serial I O A D Converter
With 11-Channel Multiplexer
General Description
The ADC0811 is an 8-Bit successive approximation A D
converter with simultaneous serial I O The serial input con-
trols an analog multiplexer which selects from 11 input
channels or an internal half scale test voltage
An input sample-and-hold is implemented by a capacitive
reference ladder and sampled data comparator This allows
the input signal to vary during the conversion cycle
Separate serial I O and conversion clock inputs are provid-
ed to facilitate the interface to various microprocessors
Features
Y Separate asynchronous converter clock and serial data
I O clock
Y 11-Channel multiplexer with 4-Bit serial address logic
Y Built-in sample and hold function
Y Ratiometric or absolute voltage referencing
Y No zero or full-scale adjust required
Y Internally addressable test voltage
Y 0V to 5V input range with single 5V power supply
Y TTL MOS input output compatible
Y 0 3 standard width 20-pin dip or 20-pin molded chip
