PRODUCT OVERVIEW
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 5µA 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.
