INA226AQDGSRQ1 Röntgeninspektion

X-Ray inspection ensures product integrity by detecting internal defects without damaging external packaging. It reduces failure rates and enhances production efficiency, making it indispensable in the electronics components industry.

INA226AQDGSRQ1 Allgemeine Beschreibung

The INA226-Q1 is a current shunt and power monitor with an IC™- or SMBUS-compatible interface. The device monitors both a shunt voltage drop and bus supply voltage. Programmable calibration value, conversion times, and averaging, combined with an internal multiplier, enable direct readouts of current in amperes and power in watts.

The INA226-Q1 senses current on common-mode bus voltages that can vary from 0 V to 36 V, independent of the supply voltage. The device operates from a single 2.7-V to 5.5-V supply, drawing a typical of 330 µA of supply current. The device is specified over the operating temperature range between –40°C and 125°C and features up to 16 programmable addresses on the IC-compatible interface.
