Quad Parametric Measurement Unit With Integrated 16-Bit Level Setting DACs

Product Details

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 (FOH and EXTFOH) 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.

    Product Details

    The EVAL-AD5522EBDZ is a fully featured evaluation board for the AD5522. The "D" in the model indicates the Paddle Down version of the AD5522 package. This board operates in stand alone mode or in conjunction with a USB to PC interface. When operated with the USB to PC interface, software is provided enabling the user to perform control of the PMU channels in addition to measurement of the different voltage and current parameters via the on board AD7685 ADC. This software includes the technical note describing the operation and set up of the EVAL-AD5522EBDZ board.
