Overview
The DAC7744EBG4 is a 16-bit, quad voltage output digital-to-analog converter (DAC) produced by Texas Instruments (formerly Burr-Brown). It is designed to provide high accuracy and reliability over a wide temperature range. The DAC7744EBG4 accepts 16-bit parallel input data and features double-buffered DAC input logic, allowing for simultaneous updates of all four DACs. It also includes a readback mode for the internal input registers and programmable asynchronous reset, which can clear all registers to either a mid-scale code of 8000H or a zero-scale code of 0000H. The device operates from either a single +15V supply or from a combination of +15V, -15V, and +5V supplies.
