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 MICROWIREserial
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.
