Dual Per-Pin Parametric

Measurement Units

General Description

Features

♦ Force Voltage/Measure Current (FVMI)

♦ Force Current/Measure Voltage (FIMV)

♦ Force Voltage/Measure Voltage (FVMV)

♦ Force Current/Measure Current (FIMI)

♦ Force Nothing/Measure Voltage (FNMV)

The MAX9951/MAX9952 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.

The MAX9951/MAX9952 force or measure voltages in the

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

♦ Force Nothing/Measure Current (FNMI,

Range E Only)

the supply voltage (V

and V ). The devices handle

supply voltages of up to +30V (V

to V ) and a 20V

♦ Termination/Measure Current

♦ Termination/Measure Voltage

device-under-test (DUT) voltage swing at full current. The

MAX9951/MAX9952 also force or measure currents up to

±±6mA with a lowest full-scale range of ±2ꢀA. ꢁntegrated

support circuitry facilitates use of an external buffer ampli-

fier for current ranges greater than ±±6mA.

♦ Five Programmable Current Ranges

±±ꢀꢀ2µ

±±mµ

A voltage proportional to the measured output voltage

or current is provided at the MSR_ output. ꢁntegrated

comparators, with externally set voltage thresholds,

provide detection for both voltage and current levels.

The MSR_ and comparator outputs can be placed in a

high-impedance state. Separate FORCE and SENSE

connections are short-circuit protected for voltages

±ꢁ6mµ

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

Range

♦ Force-Current/Measure-Current µdjustable-

Voltage Offset (IOS)

♦ Programmable Voltage Clamps at Force Output

from (V - 0.3V) to (V

+ 0.3V). The FORCE output

♦ Low-Leakage, High-Impedance Measure, and

also features a low-leakage, high-impedance state.

Force States

ꢁntegrated voltage clamps limit the force output to lev-

els set externally. The force-current or the measure-cur-

rent voltage can be offset -0.2V to +6.6V (ꢁOS). This

feature allows for the centering of the control or mea-

sured signal within the external DAC or ADC range.

♦ 3-Wire Serial Interface

♦ Low ꢁmµ (max) Quiescent Current per PMU

Ordering Information

The MAX9951D/MAX9952D feature an integrated 10k

force-sense resistor between FORCE_ and SENSE_.

The MAX9951F/MAX9952F have no internal force-sense

resistor. These devices are available in a ±6-pin, 10mm

x 10mm, 0.5mm pitch TQFP package with an exposed

8mm x 8mm die pad on the top (MAX9951) or the bot-

tom (MAX9952) of the package for efficient heat

removal. The exposed pad is internally connected to
