DAC2904Y/250 TI DAC | 48-TQFP（7X7） | 250MSPS, Dual 14-Bit

Product Overview

The DAC2904Y/250 is a high-performance, dual 14-bit digital-to-analog converter (DAC) from Texas Instruments, designed for demanding applications requiring high speed and precision. Operating at a maximum update rate of 250 MSPS, it delivers excellent dynamic performance with low glitch energy and high spurious-free dynamic range (SFDR). The device is housed in a compact 48-pin TQFP (7x7 mm) package, making it suitable for space-constrained designs. It features a flexible digital interface, including LVDS-compatible inputs, and operates from a single 3.3V supply. The DAC2904Y/250 is ideal for communications, instrumentation, and radar systems.
