Overview
The DAC7611UB is a 12-bit digital-to-analog converter (DAC) produced by Texas Instruments. It is designed to provide high performance and reliability 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, 2.435V reference, DAC, and a high-speed rail-to-rail output amplifier. This DAC is particularly noted for its fast settling time of 7µs to 1 LSB and its low power consumption of 2.5mW (0.5mA at 5V).
