General Description

The ADC08131/ADC08134/ADC08138 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.

All three devices provide a 2.5V band-gap derived reference with guaranteed performance over temperature.

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
  • 4- or 8-channel input multiplexer options with address logic
  • On-chip 2.5V band-gap reference (±2% over temperature guaranteed)
  • No zero or full scale adjustment required
  • TTL/CMOS input/output compatible
  • 0V to 5V analog input range with single 5V power supply
