Overview
The DAC7644E/1KG4, produced by Texas Instruments, is a 16-bit, quad voltage output digital-to-analog converter (DAC) that offers high precision and reliability. This device is designed to provide guaranteed 15-bit monotonic performance 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 DAC7644E/1KG4 can operate from either a single +5V supply or from +5V and –5V supplies, making it versatile for various applications.
