MAX9951 Overview
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).
Key Features
- 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
