Dual Per-Pin Parametric Measurement Units
General Description
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.
The MAX9949/MAX9950 force or measure voltages in
the -2V to +7V through -7V to +13V ranges, dependent
upon the supply voltage (V
CC
and V
EE
). The devices
handle supply voltages of up to +30V (V
CC
to V
EE
) 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
±2µA. Integrated support circuitry facilitates use of an
external buffer amplifier for current ranges greater than
±25mA.
A voltage proportional to the measured output voltage
or current is provided at the MSR_ output. Integrated
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. Integrated 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 (IOS).
This feature allows for the centering of the control or
measured signal within the external DAC or ADC range.
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
exposed paddle is internally connected to V
EE
. The
MAX9949/MAX9950 are specified over the commercial
(0°C to +70°C) temperature range.
