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
