ADCV08832 (ACTIVE)

Low Voltage, 8-Bit Serial I/O CMOS A/D Converter With Sample/Hold

 

Description

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.


Features

  • 3-wire serial digital data link requires few I/O pins
  • Single supply 2.7V to 5V
  • Analog input track/hold function
  • Analog input voltage range from GND to VCC
  • No zero or full scale adjustment required
  • TTL/CMOS input/output compatible
  • Superior pin compatible replacement for TLV0832 and ADC0832
