MAX9951, MAX9952 Dual Per-Pin Parametric Measurement Units

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 (VCC and VEE). The devices handle supply voltages of up to +30V (VCC to VEE) 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 2A. Integrated support circuitry facilitates use of an external Buffer Amplifier 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 (VEE - 0.3V) to (VCC + 0.3V). The FORCE output also features a low-leakage, high-impedance state.
Integrated voltage clamps limit the force output to levels set externally. The force-current or the measure-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 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 64-pin, 10mm x 10mm, 0.5mm pitch TQFP package with an exposed 8mm x 8mm die pad on the top MAX9951 or the bottom MAX9952 of the package for efficient heat removal. The exposed pad is internally connected to VEE. The MAX9951 MAX9952 are specified over the commercial 0C to +70C temperature range.
