QA-1000HC

QA-1000HC Full Featured Programmable Analog Supply Current Monitor FEATURES Wide IDDX Measurement BW: 0 – 5 MHz High IDDX resolution: 300 µARMS High IDDX Measurement Range: 0 – 2 A High Loading Capacitance: 0 – 100 µF Low internal resistance: 25mΩ APPLICATIONS Continuous Analog Supply Current Measurement Static and transient Analog Supply Current Measurements Positive and negative supply and ground current measurement Analog Current Measurements DESCRIPTION The QA-1000HC is a configurable analog supply current monitor, designed for loadboard applications. Its low internal resistance ensures its transparency (causing only a negligible voltage drop when inserted into the supply or ground path of the device under test). The module is designed to be inserted between the DUT supply provided by the ATE and the supply pin of the DUT or between ground and DUT ground. The VDUT supply can be positive or negative (VDD/VCC or VSS/VEE). The QA-1000HC is designed to accurately measure analog (supply) currents up to 2A (upon demand the range can be adapted to 100mA, 200mA, 500mA, 1A or 5A), thereby providing a high measurement repeatability. The monitor has a bandwidth of 5MHz, offers a resolution of 300µA @2A, and is capable to drive high capacitive loads up to 100uF. The resolution and performance of the monitor is a function of the selected bandwidth and the value of the loading capacitance CL (the DUT local on-pin supply decoupling capacitance). The QA-1000HC has no digital control pi...
