Overview
The DAC7744EC/1K is a 16-bit, quad voltage output digital-to-analog converter (DAC) produced by Texas Instruments. This device is designed to provide high accuracy and reliability over a wide temperature range, making it suitable for various industrial and automated applications. The DAC7744EC/1K features double-buffered DAC input logic, allowing for simultaneous updates of all DACs, and includes a readback mode for the internal input registers. It operates from either a single +15V supply or from a combination of +15V, –15V, and +5V supplies.
