Overview
The DAC7744E/1KG4 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 specified temperature range of –40°C to +85°C. It features double-buffered DAC input logic, allowing for simultaneous updates of all DACs, and includes a readback mode for the internal input registers. The DAC7744E/1KG4 operates from either a single +15V supply or from a combination of +15V, –15V, and +5V supplies, making it versatile for various applications.
