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 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. Key Specification (For 3.3V supply, typical, unless otherwise noted) Resolution 8 bits Conversion time (fCLK = 500 kHz) 16 µs (max) Power dissipation 1.7 mW Power down mode <0.1 µW Total Unadjusted Error ±0.8 LSB No missing codes over temperature (-40°C to +125°C) Applications • Digitizing sensors and waveforms • Process control monitoring • Remote sensing in noisy environments • Instrumentation • Embedded systems • Low power circuits

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
