ADCV08832

ADCV08832 Low Voltage, 8-Bit Serial I/O CMOS A/D Converter with Sample/Hold Function May 2001 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 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. n TTL/CMOS input/output compatible n Superior pin compatible replacement for TLV0832 and ADC0832 Applications n n n n n n Digitizing sensors and waveforms Process control monitoring Remote sensing in noisy environments Instrumentation Embedded systems Low power circuits Key Specifications (For 3.3V supply, typical, unless otherwise noted) n Resolution 8 bits n Conversion time (fCLK = 500 kHz) 16 µs (max) n Power dissipation 1.7 mW < 0.1 µW n Power down mode ± 0.8 LSB n Total Unadjusted Error n No missing codes over temperature (−40˚C to +125˚C) Features n n n n n 3-wire serial digital data link r...
