DAC8822QBDBTR TI Dual 16-Bit DAC | 38-TSSOP | ±1 LSB INL, 2.7-5.5V

Product Overview

The DAC8822QBDBTR is a dual, 16-bit, serial-input, voltage-output digital-to-analog converter (DAC) from Texas Instruments. It operates from a single 2.7V to 5.5V supply and features a precision internal reference (2.5V) and a rail-to-rail output amplifier. The device is available in a 38-pin TSSOP package and is specified over the extended industrial temperature range of -40°C to +125°C. The DAC8822 offers excellent linearity with ±1 LSB INL and ±1 LSB DNL, making it suitable for high-accuracy applications.
