The AD5522 is a high performance, highly integrated parametric measurement unit consisting of four independent channels. Each PPMU channel includes five, 16-bit, voltage out DACs setting the programmable inputs levels for the force voltage input, clamp and comparator inputs (high and low). Five programmable force and measure current ranges are available ranging from 5A to 64mA. Four of these ranges use on chip sense resistors, while a high current range up to 64mA is available per channel using off chip sense resistors. Currents in excess of 64mA require an external amplifier. Low capacitance DUT connections (FOH, EXT FOH) ensure the device is suited to relay less test systems. The PMU functions are controlled via a simple three wire serial interface compatible with SPI/QSPI/Microwire and DSP interface standards. Interface clocks of 50MHz allow fast updating of modes. LVDS (Low Voltage Differential Signaling) interface protocol at 100MHz is also supported. Comparator outputs are provided per channel for device go no-go testing and characterization. Control registers provide easy way of changing force or measure conditions, DAC levels and selected current ranges. SDO (serial data out) allows the user to readback information for diagnostic purposes.
