The ADCV08832 is a low voltage, 8-Bit successive approximation analog-to-digital converter with a 3-wire serial interface. 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 performing 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 combinations of single-ended, differential, or pseudo-differential modes.
