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.

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)
♦ Five Programmable Current Ranges
    ±2µA
    ±20µA
    ±200µA
    ±2mA
    ±25mA
♦ -2V to +7V Through -7V to +13V Input Voltage Range and Higher (Up to 20V Voltage Swing at Full Current)
♦ Force-Current/Measure-Current Voltage Offset (IOS)
♦ Programmable Voltage Clamps for the Force Output
♦ Low-Leakage, High-Z Measure State
♦ 3-Wire Serial Interface
♦ Low Power, 8mA (max) per PMU

Applications
    Memory Testers
    VLSI Testers
    System-on-a-Chip Testers
    Structural Testers
