Features • 3-wire serial digital data link requires few I/O pins • Analog input track/hold function • 2-channel input multiplexer option with address logic • 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 ADC0831/2 Description The ADC08831/ADC08832 are 8-bit successive approximation Analog to Digital converters with 3-wire serial interfaces and a configurable input multiplexer for 2 channels. The serial I/O will interface to COPS™family of micro-controllers, PLD's, microprocessors, DSP's, 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 ADC08831/ADC08832 automatically go into low power mode whenever they are not performing conversions. A track/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. The voltage reference input can be adjusted to allow encoding of small analog voltage spans to the full 8-bits of resolution. Key Specification • Resolution: 8 bits • Conversion time (fC = 2 MHz): 4µs (max) • Power dissipation: 8.5mW (typ) • Low power mode: 3.0mW (typ) • Single supply: 5VDC • Total unadjusted error: ±1LSB • No missing codes over temperature Applications • Digitizing sensors and waveforms • Process control monitoring • Remote sensing in noisy environments • Instrumentation • Embedded Systems

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.
