CS4373A Datasheet PDF - Cirrus Logic

Description
The CS4373A is a high-performance, differential output digital-to-analog converter (DAC) with programmable attenuation and multiple operational modes. AC test modes measure system dynamic performance through THD and CMRR tests while DC test modes are for gain calibration and pulse tests.
