Overview
The DAC7714UB/1K is a quad, serial input, 12-bit, voltage output Digital-to-Analog Converter (DAC) produced by Texas Instruments. This device is designed to provide guaranteed 12-bit monotonic performance over a temperature range of –40°C to +85°C. It features a low power consumption of up to 250mW and is available in a small SO-16 package, making it ideal for various applications such as process control, data acquisition systems, and closed-loop servo-control. The DAC7714 can be powered from either a single +15V supply or dual ±15V supplies and includes an asynchronous reset function that sets all DAC registers to either zero-scale or mid-scale, selectable via the RESETSEL pin.
