Overview
The DAC7614PB is a quad, serial input, 12-bit, voltage output digital-to-analog converter (DAC) produced by Burr-Brown (now part of Texas Instruments). It is designed to provide guaranteed 12-bit monotonic performance over a temperature range of –40°C to +85°C. The device features low power consumption, unipolar or bipolar operation, and a fast settling time of 10µs to 0.012%. It is available in various packages, including 16-pin plastic DIP, 16-lead SOIC, and 20-lead SSOP, making it suitable for a wide range of applications.
