ADI LTC1446IS8

Voltage - BufferedSPI5V-40°C ~ 85°C

Overview

The LTC1446/LTC1446L are dual 12-bit digital-to-analog converters (DACs) available in an SO-8 package. They are complete with a rail-to-rail voltage output amplifier, an internal reference and an easy-to-use 3-wire cascadable serial interface.

The low power supply current makes the LTC1446IS8 family ideal for battery-powered applications. These DACs are available in space saving 8-pin SO and PDIP packages and require no external components for operation.
