General Description

This series of CMOS 10-bit plus sign successive approximation A/D converters features versatile analog input multiplexers, sample/hold and a 2.5V band-gap reference. The 1-, 2-, 4-, or 8-channel multiplexers can be software configured for single-ended or differential mode of operation.

An input sample/hold is implemented by a capacitive reference ladder and sampled-data comparator. This allows the analog input to vary during the A/D conversion cycle.

In the differential mode, valid outputs are obtained even when the negative inputs are greater than the positive because of the 10-bit plus sign output data format.

The serial I/O is configured to comply with the NSC MICROWIRE™ serial data exchange standard for easy interface to the COPS™ and HPC™ families of controllers, and can easily interface with standard shift registers and microprocessors.

Features

  • 0V to 5V analog input range with single 5V power supply
  • Serial I/O (MICROWIRE compatible)
  • 1-, 2-, 4-, or 8-channel differential or single-ended multiplexer
  • Software or hardware power down
  • Analog input sample/hold function
  • Ratiometric or absolute voltage referencing
  • No zero or full scale adjustment required
  • No missing codes over temperature
  • TTL/CMOS input/output compatible
  • Standard DIP and SO packages
