Data Acquisition - Digital to Analog Converters (DAC)

Digital to Analog Converters (DACs) are electronic circuits that convert a digital numerical value into a corresponding analog voltage or current. The DAC7654YCRG4 is an 8-bit DAC with a small QFN embedded package. This device has four input codes, making it ideal for high-resolution data acquisition applications. It features low power consumption and high performance, making it suitable for battery-powered data acquisition projects.

Device Overview

The DAC7654YCRG4 digital-to-analog converter consists of four 8-bit binary input registers, an 8-bit DAC output, and an output amplifier. All the setting of the control inputs, data inputs, and the reference voltage are controlled by the SPI-bus controller. The SPI-bus controller enables the device to receive commands, transfer data, and write settings from an external source.

The DAC7654YCRG4 has a supply voltage range of 2.4V to 3.6V and a max operating temperature range of -40°C to +85°C. It also features an integrated charge pump to provide a stable supply of power.
