Product Introduction

Overview

The AD9750AR is a 10-bit resolution, high-performance digital-to-analog converter (DAC) from Analog Devices Inc. It is part of the TxDAC series, which is optimized for the transmit signal path of communication systems. This DAC offers exceptional AC and DC performance, supporting update rates up to 125 MSPS. The AD9750AR is manufactured using an advanced CMOS process and features a segmented current source architecture combined with a proprietary switching technique to enhance dynamic performance. It includes edge-triggered input latches and a 1.2 V temperature-compensated bandgap reference, providing a complete monolithic DAC solution.
