ADCV08832
Low Voltage, 8-Bit Serial I/O CMOS A/D Converter with
Sample/Hold Function
General Description
The ADCV08832 is a low voltage, 8-Bit successive approxi-
mation analog-to-digital converter with a 3-wire serial inter-
face. The serial I/O will interface to microcontrollers, PLD’s,
microprocessors, DSPs or shift registers. The serial I/O is
configured to comply with the NSC MICROWIRE™ serial
data exchange standard.
To minimize total power consumption, the ADCV08832 can
be set to go into low power mode whenever it is not perform-
ing conversions.
A sample/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 com-
binations of single-ended, differential, or pseudo-differential
modes.
