Overview
The AD5522JSVDZ from Analog Devices Inc. is a high-performance, highly integrated parametric measurement unit (PMU) designed for advanced testing and measurement applications. This device features four independent channels, each equipped with five 16-bit, voltage output digital-to-analog converters (DACs) that set the programmable input levels for force voltage inputs, clamp inputs, and comparator inputs. The AD5522 is particularly suited for use in automatic test equipment (ATE) due to its comprehensive set of measurement and force capabilities.
