Overview
The DAC7612U, produced by Texas Instruments, is a dual, 12-bit digital-to-analog converter (DAC) designed for high-performance applications. It guarantees 12-bit monotonicity performance over the industrial temperature range of -40°C to +85°C. The device operates on a single +5V supply and includes an input shift register, latch, a 2.435V reference, a dual DAC, and high-speed rail-to-rail output amplifiers. Each output settles to 1 LSB within 7µs, making it suitable for applications requiring fast and precise analog output.
