ACS723LLCTR-10AU-T Applications
The ACS723 outputs an analog signal, VIOUT, that changes, proportionally, with the bidirectional AC or DC primary sensed current, IP, within the specified measurement range. The BW_SEL pin can be used to select one of the two bandwidths to optimize the noise performance. Grounding the BW_SEL pin puts the part in the high bandwidth, 80 kHz, mode.

ACS723LLCTR-10AU-T FAQ
1. Can ACS712 measure small current?
The ACS712 current sensor is capable of measuring up to 5A of DC or AC current. For more sensitive current measurements, we added an opamp gain stage. You may measure extremely tiny currents by increasing the gain (from 4.27 to 47). The analog voltage generated by the ACS712 Low Current Sensor Breakout changes linearly with the measured current.
2. What is ACS712 current sensor?
The ACS712 is a current sensor that can work in both AC and DC modes. This sensor runs on 5V and outputs an analog voltage proportionate to the detected current. This gadget is made up of a set of precise Hall sensors connected by copper cables.
3. What is a CT sensor?
CT sensors, also known as current transformers or current sensors, are devices that measure the current flowing through a wire by detecting the current and producing a proportional output. CT sensors can detect both alternating current (AC) and direct current (DC) in a circuit.
