ADC08831/ADC08832
8-Bit Serial I/O CMOS A/D Converters with Multiplexer
and Sample/Hold Function
General Description
The ADC08831/ADC08832 are 8-bit successive approxima-
tion Analog to Digital converters with 3-wire serial interfaces
and a configurable input multiplexer for 2 channels. The se-
rial I/O will interface to COPS
family of micro-controllers,
PLD’s, microprocessors, DSP’s, or shift registers. The serial
I/O is configured to comply with the NSC MICROWIRE
se-
rial data exchange standard.
To
minimize
total
power
ADC08831/ADC08832 automatically go into low power
mode whenever they are not performing conversions.
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. The voltage reference input can
be adjusted to allow encoding of small analog voltage spans
to the full 8-bits of resolution.
