Product Introduction

Overview

The DAC5672IPFB is a high-performance, 14-bit dual-channel digital-to-analog converter (DAC) produced by Texas Instruments. This device is designed for high-speed applications, offering an update rate of up to 275 million samples per second (MSPS). It operates on a single supply voltage ranging from 3 V to 3.6 V, making it versatile for various system designs. The DAC5672IPFB features an on-chip 1.2-V reference voltage and supports both independent and interleaved data modes, making it suitable for a wide range of communication and instrumentation applications.
