Overview
The DAC80508ZCRTER is a part of the DACx0508 family, a series of low-power, eight-channel, buffered voltage-output digital-to-analog converters (DACs) offered by Texas Instruments. These DACs are available in 16-, 14-, and 12-bit resolutions and are designed to provide high performance and flexibility in various applications. The DAC80508ZCRTER includes an integrated 2.5-V precision internal reference, eliminating the need for an external precision reference in most cases. It operates from a single 2.7-V to 5.5-V supply and is characterized for operation over a temperature range of –40°C to 125°C, making it suitable for a wide range of industrial and automotive applications.
