AD5522
GENERAL DESCRIPTION
The AD5522 is a high performance, highly integrated parametric
measurement unit consisting of four independent channels. Each
per-pin parametric measurement unit (PPMU) channel includes
five 16-bit, voltage output DACs that set the programmable input
levels for the force voltage inputs, clamp inputs, and comparator
inputs (high and low). Five programmable force and measure
current ranges are available, ranging from ±5 μA to ±80 mA.
Four of these ranges use on-chip sense resistors; one high current
range up to ±80 mA is available per channel using off-chip sense
resistors. Currents in excess of ±80 mA require an external ampli-
fier. Low capacitance DUT connections (FOHx and EXTFOHx)
ensure that the device is suited to relayless test systems.

The PMU functions are controlled via a simple 3-wire serial
interface compatible with SPI, QSPI™, MICROWIRE™, and DSP
interface standards. Interface clocks of 50 MHz allow fast updating
of modes. The low voltage differential signaling (LVDS) interface
protocol at 83 MHz is also supported. Comparator outputs are
provided per channel for device go-no-go testing and character-
ization. Control registers allow the user to easily change force or
measure conditions, DAC levels, and selected current ranges.
The SDO (serial data output) pin allows the user to read back
information for diagnostic purposes.
