Overview
The DAC7714UB, produced by Texas Instruments, is a quad, serial input, 12-bit, voltage output Digital-to-Analog Converter (DAC). It guarantees 12-bit monotonic performance over a temperature range of –40°C to +85°C. This device features an asynchronous reset that clears all registers to either mid-scale (800H) or zero-scale (000H), selectable via the RESETSEL pin. The DAC7714UB can be powered from a single +15V supply or from dual +15V and –15V supplies, making it versatile for various applications.
