Description

The AD53032 is a single chip that performs the pin electronicsfunctions of driver, comparator and active load in ATE VLSI
and memory testers. In addition, a Schottky diode bridge for theactive load and a VCOM buffer are included internally.The driver is a proprietary design that features three activestates: Data High Mode, Data Low Mode and Term Mode aswell as an Inhibit State. This facilitates the implementation ofhigh speed active termination. The output voltage range is 3 Vto +8 V to accommodate a wide variety of test devices. Theoutput leakage is typically less than 250 nA over the entire signalrange.

The dual comparator AD53032, with an input range equal to the driveroutput range, features built-in latches and ECL-compatibleoutputs. The outputs are capable of driving 50 W signal linesterminated to 2 V. Signal tracking capability is upwards of5 V/ns.

The active load of AD53032 can be set for up to 35 mA load current withless than a 10 mA linearity error through the entire set range.IOH, IOL and the buffered VCOM are independently adjustable.Onboard Schottky diodes provide high speed switching and lowcapacitance.

Also included on the chip is an onboard temperature sensorwhose purpose is to give an indication of the surface temperatureof the DCL. This information of AD53032 can be used to measure qJCand qJA or flag an alarm if proper cooling is lost. Output fromthe sensor is a current sink that is proportional to absolute temperature.The gain is trimmed to a nominal value of 1.0 mA/K.As an example, the output current can be sensed by using a10 kW resistor connected from +10 V to the THERM (IOUT) pin.A voltage drop across the resistor will be developed that equals:10K ´ 1 mA/K = 10 mV/K = 2.98 V at room temperature.
