ADC08131/ADC08134/ADC08138
8-Bit High-Speed Serial I/O A/D Converters with
Multiplexer Options, Voltage Reference, and Track/Hold
Function
General Description
The ADC08131/ADC08134/ADC08138 are 8-bit successive
approximation A/D converters with serial I/O and config-
urable input multiplexers with up to 8 channels. The serial
I/O is configured to comply with the NSC MICROWIRE
serial data exchange standard for easy interface to the
COPS
family of controllers, and can easily interface with
standard shift registers or microprocessors.
All three devices provide a 2.5V band-gap derived reference
with guaranteed performance over temperature.
Atrack/hold function allows the analog voltage at the positive
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-differential modes. In addition, input voltage spans
as small as 1V can be accommodated.
