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
se-
rial 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,
pseudo-differential modes. In addition, input voltage spans
as small as 1V can be accommodated.
