Overview
The DAC7612UG4 is a dual, 12-bit digital-to-analog converter (DAC) produced by Burr-Brown, now part of Texas Instruments. This device is designed to provide high performance and reliability over the industrial temperature range of –40°C to +85°C. It operates on a single +5V supply and features a synchronous serial interface compatible with various DSPs and microcontrollers. The DAC7612UG4 includes an input shift register, latch, 2.435V reference, dual DACs, and high-speed rail-to-rail output amplifiers. Each output settles to 1 LSB within 7µs, making it suitable for applications requiring fast and accurate analog output.
