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 ±2?A. Integrated support circuitry facilitates use of an external buffer ampli fier for current ranges greater than ±64mA.
