Current Sensor Module ACS712 5A

Current Sensor Module ACS712 5A provides economical and precise solutions for AC or DC current sensing in industrial, Commercial and communications systems. The maximum AC or DC that can be detected can reach 5A, and the present current signal can be read via analog I / O port of Arduino. The device package allows for easy implementation by the customer. 

The module consists of a precise, low-offset, linear Hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field which the Hall IC converts into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer. A precise, proportional voltage is provided by the low-offset, chopper-stabilized BiCMOS Hall IC, which is programmed for accuracy after packaging.

Features :

• Low-noise analog signal path.
• Device bandwidth is set via the new FILTER pin.
• 5 µs output rise time in response to step input current.
• Small footprint, low-profile SOIC8 package.
• 2.1 kV RMS minimum isolation voltage from pins 1-4 to pins 5-8.
• 5.0 V, single-supply operation.
• 66 to 185 mV/A output sensitivity.
• Output voltage proportional to AC or DC currents.
• Factory-trimmed for accuracy.
• Extremely stable output offset voltage.
• Nearly zero magnetic hysteresis.
• The ratio metric output from the supply voltage.
