Overview
The DAC7714UG4 is a quad, serial input, 12-bit, voltage output Digital-to-Analog Converter (DAC) produced by Texas Instruments. This device is designed to provide high performance and reliability over a wide temperature range of –40°C to +85°C. It features guaranteed 12-bit monotonic performance, low power consumption, and the ability to operate in both unipolar and bipolar modes.
The DAC7714UG4 is housed in a small SO-16 package, making it ideal for applications where space is limited. It can be powered from either a single +15V supply or dual ±15V supplies, offering flexibility in system design. The device includes an asynchronous reset function that sets all DAC registers to either zero-scale or mid-scale, depending on the state of the RESETSEL pin.
