ACS72981LLRATR-100B5 Frequently Asked Questions (FAQ)
-
A good PCB layout for the ACS72981LLRATR-100B5 involves keeping the sense lines as short as possible, using a ground plane to reduce noise, and placing the device close to the current-carrying conductor. Allegro provides a recommended PCB layout in their application note AN296065.
-
Calibration of the ACS72981LLRATR-100B5 involves applying a known current to the device and adjusting the output voltage to match the expected value. Allegro provides a calibration procedure in their application note AN296065.
-
The maximum allowable voltage on the VCC pin of the ACS72981LLRATR-100B5 is 5.5V. Exceeding this voltage may damage the device.
-
The ACS72981LLRATR-100B5 is designed to measure DC currents, but it can also be used to measure AC currents with some limitations. The device can measure AC currents up to 50 kHz, but the output voltage will be proportional to the RMS value of the current.
-
The ACS72981LLRATR-100B5 has a temperature coefficient of ±0.1% per °C, which means that the output voltage will vary by ±0.1% for every 1°C change in temperature. This can affect the accuracy of the current measurement.
