Overview
The DAC7614E/1K, produced by Texas Instruments, is a quad, serial input, 12-bit, voltage output digital-to-analog converter (DAC). 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 20mW and supports both unipolar and bipolar operation. The DAC7614E/1K is ideal for applications requiring precise analog output, such as process control, data acquisition systems, and closed-loop servo-control. The device can be powered from either a single +5V supply or dual ±5V supplies and is available in various package options including 16-pin plastic DIP, 16-lead SOIC, and 20-lead SSOP packages.
