DAC7641YB/2K TI 16-Bit DAC | 32-TQFP (5x5) | 2-Ch, Serial Input

Product Overview

The DAC7641YB/2K is a 16-bit, dual-channel, voltage-output digital-to-analog converter (DAC) from Texas Instruments. It operates from a single +5V supply and features a serial interface (SPI-compatible) with a 30 MHz clock rate. The device is offered in a compact 32-pin TQFP (5x5 mm) package, making it ideal for space-constrained applications. It includes an internal reference (2.5V) and output amplifiers, providing a full-scale output range of 0V to +5V (with external reference up to Vref*2). The DAC7641YB/2K is specified for industrial temperature range (-40°C to +85°C) and is available in tape-and-reel packaging (2K units).
