AD5449 - Multiplying DACs

Download the AD5449 datasheet PDF. This datasheet also covers the AD5429 variant, as both devices belong to the same multiplying dacs family and are provided as variant models within a single manufacturer datasheet.

General Description

The AD5429/AD5439/AD54491 are CMOS 8-, 10-, and 12-bit dual-channel current output digital-to-analog converters, respectively.

These devices operate from a 2.5 V to 5.5 V power supply, making them suited to battery-powered and other applications.

Key Features

  • 10 MHz multiplying bandwidth 50 MHz serial interface 2.5 V to 5.5 V supply operation ±10 V reference input Pin compatible 8-, 10-, and 12-bit DACs Extended temperature range:.
  • 40°C to +125°C 16-lead TSSOP package Guaranteed monotonic Power-on reset Daisy-chain mode Readback function 0.5 µA typical current consumption.
