High Isolation Linear Current Sensor IC with 850 μΩ Current Conductor

ACS718

These parts are in production but have been determined to be NOT FOR NEW DESIGN. The ACS718 is an economical, high-isolation current sensor IC for AC/DC sensing, ideal for space-constrained applications. It features a low-offset Hall sensor with a 0.85mΩ copper conduction path, providing a proportional voltage output and electrical isolation for high-side current sensing.

Top Features

IEC/UL 60950-1 Ed. 2 certified to:
- Dielectric Strength = 4800 Vrms (tested for 60 seconds)
- Basic Isolation = 1550 Vpeak
- Reinforced Isolation = 800 Vpeak
Small footprint, low-profile SOIC16 wide-body package suitable for space constrained applications that require high galvanic isolation
0.85 mΩ primary conductor for low power loss and high inrush current withstand capability
Low, 350 μA_RMS/√Hz noise density results in typical input referred noise of 70 mA(rms) at max bandwidth (40 kHz)
5.0 V, single supply operation
Output voltage proportional to AC or DC current
Factory-trimmed sensitivity and quiescent output voltage for improved accuracy
Chopper stabilization results in extremely stable quiescent output voltage
Ratiometric output from supply voltage
