DAC1221E/2K5 TI 16-Bit DAC | 16-SSOP | 2.7V-5.5V, 1.5mW

Product Overview

The DAC1221E/2K5 is a high-precision, 16-bit digital-to-analog converter (DAC) from Texas Instruments, designed for low-power and portable applications. It operates from a single 2.7V to 5.5V supply and consumes only 1.5mW typical power, making it ideal for battery-powered systems. The device features a serial interface (SPI-compatible) and includes an internal reference and output amplifier, simplifying design. Housed in a compact 16-SSOP package, the DAC1221E/2K5 offers excellent linearity and low noise for demanding industrial and instrumentation applications.
