DAC8734SPFBR TI Digital-to-Analog Converter | 48-TQFP (7x7) | 4-Ch, 16-Bit, ±1 LSB INL

Product Overview

The DAC8734SPFBR is a high-performance, quad-channel, 16-bit digital-to-analog converter (DAC) from Texas Instruments. It offers excellent linearity and low noise, making it ideal for precision industrial and automotive applications. The device operates from a single 2.7V to 5.5V supply and features a flexible serial interface. Housed in a compact 48-TQFP (7x7 mm) package, it provides four independent DAC channels with rail-to-rail output buffers.
