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 set voltage thresholds, provide detection for both voltage and current levels. The MSR_ and comparator outputs can be placed in a 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 MAX9949D/MAX9950D feature an integrated 10kΩ force-sense resistor between FORCE_ and SENSE_. The MAX9949F/MAX9950F 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 (MAX9949) or the bottom (MAX9950) of the package for efficient heat removal. The exposed paddle is internally connected to VEE. The MAX9949/MAX9950 are specified over the commercial (0°C to +70°C) temperature range.
