Overview
The DAC7634EBG4 is a 16-bit, quad voltage output digital-to-analog converter (DAC) produced by Texas Instruments. This device is designed for high precision and low power consumption, making it ideal for various industrial and automotive applications. The DAC7634EBG4 operates with a specified 15-bit monotonic performance over a temperature range of –40°C to 85°C and can be powered from either a single 5-V supply or dual ±5-V supplies.
The device features double-buffered data inputs, allowing simultaneous update of all four DACs, and provides a serial data output for daisy-chaining multiple DACs. It also includes a programmable reset function that sets all DAC output voltages and registers to either mid-scale or zero-scale codes.
