Overview
The AD5522JSVUZ, produced by Analog Devices Inc., is a high-performance, highly integrated parametric measurement unit (PMU). This device consists of four independent channels, each serving as a per-pin parametric measurement unit (PPMU). It is designed for advanced testing and measurement applications, particularly in automatic test equipment (ATE) and other high-precision measurement systems. The AD5522 features five 16-bit, voltage output digital-to-analog converters (DACs) per channel, which set the programmable input levels for force voltage, clamp inputs, and comparator inputs. The device supports multiple force and measure current ranges, from ±5 µA to ±80 mA, using both on-chip and off-chip sense resistors.
