MAX9949

19-3014; Rev 3; 6/10 Dual Per-Pin Parametric Measurement Units MAX9949/MAX9950 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 (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 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 ...
