Overview
The DAC7625UB is a 12-bit quad voltage output digital-to-analog converter (DAC) produced by Texas Instruments. This device is part of the DAC7624 and DAC7625 series, known for their high performance and versatility. The DAC7625UB operates with guaranteed 12-bit monotonic performance over a wide temperature range of -40°C to +85°C. It features double-buffered DAC input logic, allowing simultaneous updates of all DACs, and includes a readback mode for the internal input registers. The device can be powered from either a single +5V supply or dual ±5V supplies, making it suitable for various applications.
