Dual Per-Pin Parametric Measurement Units

4/MAX950

General Description

Features

The MAX9949/MAX9950 dual parametric measurement

units (PMUs) feature a small package size, wide force

and measurement range, and high accuracy, making the

devices ideal for automatic test equipment (ATE) and

other instrumentation that requires a PMU per pin or per

site.

o Force Voltage/Measure Current (FVMI)

o Force Current/Measure Voltage (FIMV)

o Force Voltage/Measure Voltage (FVMV)

o Force Current/Measure Current (FIMI)

o Force Nothing/Measure Voltage (FNMV)

The MAX9949/MAX9950 force or measure voltages in

the -2V to +7V through -7V to +13V ranges, dependent

upon the supply voltage (V

and V ). The devices

to V ) and

a 20V device under test (DUT) voltage swing at full cur-

rent. The MAX9949/MAX9950 also force or measure

currents up to 25mA with a lowest full-scale range of

2ꢀA. ꢁntegrated support circuitry facilitates use of an

external buffer amplifier for current ranges greater than

25mA.

o -±V to +7V Through -7V to +13V Input Voltage

Range and Higher (Up to ±ꢀV Voltage Swing at

Full Current)

A voltage proportional to the measured output voltage

or current is provided at the MSR_ output. ꢁntegrated

comparators, with externally set voltage thresholds, pro-

vide detection for both voltage and current levels. The

MSR_ and comparator outputs can be placed in a high-

Z state. ꢁntegrated voltage clamps limit the force output

to levels set externally. The force-current or the mea-

sure-current voltage can be offset -0.2V to +4.4V (ꢁOS).

This feature allows for the centering of the control or

measured signal within the external DAC or ADC range.

o Force-Current/Measure-Current Voltage Offset

(IOS)

o Programmable Voltage Clamps for the Force

Output

o Low-Leakage, High-Z Measure State

o 3-Wire Serial Interface

o Low Power, 8mµ (max) per PMU

The MAX9949D/MAX9950D feature an integrated 10kΩ

force-sense resistor between FORCE_ and SENSE_.

The MAX9949F/MAX9950F have no internal force-sense

resistor. These devices are available in a 64-pin 10mm x

10mm, 0.5mm pitch TQFP package with an exposed

8mm x 8mm die pad on the top (MAX9949) or the bottom

(MAX9950) of the package for efficient heat removal. The
