SPT5420 - 13-BIT / OCTAL D/A CONVERTER

General Description

The SPT5420 contains eight 13-bit digital-to-analog CMOS converters designed primarily for automatic test equipment applications.

It uses novel circuit topology to convert the 13-bit digital inputs into output voltages which are proportionate to the applied reference voltages.

Key Features

  • 13-bit resolution Pin compatible with AD7839 Eight DACs in one package Buffered voltage outputs Wide output voltage swing VDD.
  • 2.5 V to VSS+2.5 V 15 µs settling time to ±0.5 LSB Double-buffered digital inputs Microprocessor and TTL/CMOS compatible.
