DAC7742Y/250 TI Digital-to-Analog Converter | 48-LQFP (7x7) | 16-Bit, Single Channel

Product Overview

The DAC7742Y/250 is a high-performance 16-bit digital-to-analog converter (DAC) from Texas Instruments, designed for precision industrial and instrumentation applications. It features a single-channel voltage output with a settling time of 10 µs, ensuring fast and accurate conversions. The device operates from a single +5V supply and provides a bipolar output range of ±10V, making it suitable for a wide variety of control and signal generation tasks. Housed in a compact 48-LQFP (7x7 mm) package, the DAC7742Y/250 offers excellent linearity and low noise, with an integral nonlinearity (INL) of ±4 LSB and a differential nonlinearity (DNL) of ±1 LSB. Its serial interface (SPI) simplifies integration with microcontrollers and DSPs, while an internal reference and output amplifier reduce external component count.
