AMC1301 3-channel isolation current acquisition module 200KHz bandwidth three-phase motor analog isolation

Parameters
Onboard SEPIC DC-DC converter, supporting wide power supply voltages (3.3V-12V DC).
The minimum isolation voltage between channels is 2500Vdc, and the minimum isolation voltage between input and output is 2500Vdc.
The typical value of output offset voltage is 2mV.
The system gain is 8.2, and changing the differential amplifier or sampling resistor can easily change the current acquisition range.
External input reference level, which can be adjusted for different acquisition systems.
When powered by 3.3VDC, the operating current is 100mA, and when powered by 5.0VDC, the operating current is 65mA.
Support forward and reverse current collection.
The minimum simulated bandwidth of the system is 200KHz.
FAQ
Question: How to configure the use of STM32 internal ADC to collect positive and negative currents?
Answer: The default output of the module is 0-3.3V, with a zero current output level of 1.65V. It can be easily connected to 3.3V analog reference MCU or DSP. The REF pin outputs a zero current level as a reference level, with an output impedance of 5K.
