MAX9951DCCB+D

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P18P19-P21P22-P24
General Description
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
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 current. The
MAX9951/MAX9952 also force or measure currents up to
±64mA with a lowest full-scale range of ±2µA. Integrated
support circuitry facilitates use of an external buffer ampli-
fier for current ranges greater than ±64mA.
A voltage proportional to the measured output voltage
or current is provided at the MSR_ output. Integrated
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
from (V
EE
- 0.3V) to (V
CC
+ 0.3V). The FORCE output
also features a low-leakage, high-impedance state.
Integrated 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 +4.4V (IOS). This
feature allows for the centering of the control or mea-
sured signal within the external DAC or ADC range.
The MAX9951D/MAX9952D feature an integrated 10kΩ
force-sense resistor between FORCE_ and SENSE_.
The MAX9951F/MAX9952F 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 (MAX9951) or the bot-
tom (MAX9952) of the package for efficient heat
removal. The exposed pad is internally connected to
V
EE
. The MAX9951/MAX9952 are specified over the
commercial 0°C to +70°C temperature range.
