Product Introduction

Overview

The DAC8814ICDBR is a quad, 16-bit, current-output digital-to-analog converter (DAC) produced by Texas Instruments. This device is part of the DAC8814 family and is specifically packaged in a 28-lead SSOP package. It features a serial input interface compatible with the SPI protocol and is designed for applications requiring high precision and simultaneous multichannel output updates.

The DAC8814ICDBR includes internal power-on reset, which forces the output voltage to zero at system turn-on, and an MSB pin that allows system reset assertion to set registers to zero or half-scale code. The device operates over a wide power supply range of 2.7 V to 5.5 V and supports operating temperatures from -40°C to +85°C.
