A/D Converters with MUX, Reference, and Track/Hold
General Description
The ADC08231/ADC08234/ADC08238 are 8-bit succes-
sive approximation A/D converters with serial I/O and con-
figurable input multiplexers with up to 8 channels. The serial
I/O is configured to comply with the NSC MICROWIRE
TM
serial data exchange standard for easy interface to the
COPS
TM
family of controllers, and can easily interface with
standard shift registers or microprocessors.
Designed for high-speed/low-power applications, the devic-
es are capable of a fast 2
m
s conversion when used with a
4 MHz clock.
All three devices provide a 2.5V band-gap derived reference
with guaranteed performance over temperature.
A track/hold function allows the analog voltage at the posi-
tive input to vary during the actual A/D conversion.
The analog inputs can be configured to operate in various
combinations of single-ended, differential, or pseudo-differ-
ential modes. In addition, input voltage spans as small as 1V
can be accommodated.
