General Description

The ADC08031/ADC08032/ADC08034/ADC08038 are 8-bit successive approximation A/D converters with serial I/O and configurable input multiplexers with up to 8 channels. The serial I/O is configured to comply with the NSC MICROWIRE™ serial data exchange standard for easy interface to the COPS™ family of controllers, and can easily interface with standard shift registers or microprocessors.

The ADC08034 and ADC08038 provide a 2.6V band-gap derived reference. For devices offering guaranteed voltage reference performance over temperature see ADC08131, ADC08134 and ADC08138.

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. In addition, input voltage spans as small as 1V can be accommodated.

Features

  • Serial digital data link requires few I/O pins
  • Analog input track/hold function
  • 2-, 4-, or 8-channel input multiplexer options with address logic
  • 0V to 5V analog input range with single 5V power supply
  • No zero or full scale adjustment required
  • TTL/CMOS input/output compatible
  • On chip 2.6V band-gap reference
  • 0.3[Prime] standard width 8-, 14-, or 20-pin DIP package
  • 14-, 20-pin small-outline packages

Key Specification

  • Resolution: 8 bits
  • Conversion time (fC = 1 MHz): 8µs (max)
  • Power dissipation: 20mW (max)
  • Single supply: 5VDC (±5%)
  • Total unadjusted error: ±½ LSB and ±1LSB
  • No missing codes over temperature

Applications

  • Digitizing automotive sensors
  • Process control monitoring
  • Remote sensing in noisy environments
  • Instrumentation
  • Test systems
  • Embedded diagnostics
