19-3247; Rev 1; 2/05 Dual Per-Pin Parametric Measurement Units 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 (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 ±2µA. 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 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 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 0°C to +70°C temperature range. ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ 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) Force Nothing/Measure Current (FNMI, Range E Only) Termination/Measure Current Termination/Measure Voltage Five Programmable Current Ranges ±2µA ±20µA ±200µA ±2mA ±64mA -2V to +7V Through -7V to +13V Input-Voltage Range Force-Current/Measure-Current AdjustableVoltage Offset (IOS) Programmable Voltage Clamps at Force Output Low-Leakage, High-Impedance Measure, and Force States 3-Wire Serial Interface Low 6mA (max) Quiescent Current per PMU MAX9951/MAX9952 ♦ ♦ ♦ ♦ ♦ ♦ Ordering Information PART MAX9951DCCB MAX9951FCCB* MAX9952DCCB MAX9952FCCB* TEMP RANGE 0°C to +70°C 0°C to +70°C 0°C to +70°C 0°C to +70°C PIN-PACKAGE 64 TQFP-EPR 64 TQFP-EPR 64 TQFP-EP 64 TQFP-EP *Future product—contact factory for availability.
