ADCV08832 Datasheet | National Semiconductor

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 ply 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 binations of single-ended, differential, or pseudo-differential modes. n TTL/CMOS input/output patible n Superior pin patible 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 (f CLK = 500 k Hz) 16 µs (max) n Power dissipation 1.7 m W < 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 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 Connection Diagram ADCV08832 SOIC-8 Package DS200084-1 Ordering Information Temperature Range Industrial (- 40˚C ≤ TJ ≤ +125˚C) ADCV08832CIM ADCV08832CIMX Package M08A M08A Package Marking ADC08832I ADC08832I Transport Media 95 Units in Rail 2500 Units in Tape and Reel COPS™ and MICROWIRE™ are trademarks of National Semiconductor Corporation. © 2001 National Semiconductor Corporation DS200084 .national.
