ACS714LLCTR-50A-T

Allegro MicroSystems, LLC · Current Sensors · SOIC-8

ACS714LLCTR-50A-T from Allegro MicroSystems, LLC, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IP+ passive Terminal for the current being sampled; fused internally, with pins 1 and 2 tied together as the positive current input.
2 IP+ passive Terminal for the current being sampled; fused internally, with pins 1 and 2 tied together as the positive current input.
3 IP- passive Terminal for the current being sampled; fused internally, with pins 3 and 4 tied together as the negative current return.
4 IP- passive Terminal for the current being sampled; fused internally, with pins 3 and 4 tied together as the negative current return.
5 GND power_in Signal ground terminal for the device.
6 FILTER passive Terminal for an external capacitor that sets the bandwidth; the datasheet gives CF = 1 nF as the common operating condition, with RF(INT) = 1.7 kΩ typical forming an RC circuit with it.
7 VIOUT output Analog output signal; limited to 3 mA source and 10 mA sink per the absolute maximum ratings.
8 VCC power_in Device power supply terminal; 4.5 V to 5.5 V with 5.0 V typical, and 8 V absolute maximum.
