DAC8734SPFB TI Quad 16-Bit DAC | 48-TQFP (7x7) | ±1 LSB INL, 2.7-5.5V

Product Overview

The DAC8734SPFB is a quad-channel, 16-bit, voltage-output digital-to-analog converter (DAC) from Texas Instruments. It operates from a single 2.7V to 5.5V supply and offers excellent linearity with ±1 LSB INL and DNL. The device is available in a compact 48-pin TQFP (7x7 mm) package, making it ideal for space-constrained applications. It features a high-speed SPI interface (up to 50 MHz) and includes an internal reference (2.5V) with low drift (5 ppm/°C). The DAC8734SPFB is designed for industrial control, test and measurement, and communication systems.
