Overview
The DAC7634EB/1K from Texas Instruments is a 16-bit, quad voltage output digital-to-analog converter (DAC) designed for high precision and low power consumption. This device is part of the DAC7634 series and is packaged in a 48-lead SSOP package. It operates over a temperature range of -40°C to 85°C, making it suitable for a variety of industrial and automotive applications. The DAC7634EB/1K accepts 24-bit serial input data and features double-buffered DAC input logic, allowing for simultaneous updates of all four DACs. It also provides a serial data output for daisy-chaining multiple DACs.
