ACHS-7125-500E from AVAGO(Broadcom), in a SOP-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; pins 1 and 2 are shorted together on the input side, and the ACHS-7125 input peak current range is ±50 A (valid up to 85°C ambient, derated above that on 4-oz copper PCB), with primary conductor lead temperature limited to +150°C.
2	IP+	passive	Terminal for the current being sampled, fused internally; pins 1 and 2 are shorted together on the input side, and the ACHS-7125 input peak current range is ±50 A (valid up to 85°C ambient, derated above that on 4-oz copper PCB), with primary conductor lead temperature limited to +150°C.
3	IP-	passive	Terminal for the current being sampled, fused internally; pins 3 and 4 are shorted together on the input side, and the ACHS-7125 input peak current range is ±50 A (valid up to 85°C ambient, derated above that on 4-oz copper PCB), with primary conductor lead temperature limited to +150°C.
4	IP-	passive	Terminal for the current being sampled, fused internally; pins 3 and 4 are shorted together on the input side, and the ACHS-7125 input peak current range is ±50 A (valid up to 85°C ambient, derated above that on 4-oz copper PCB), with primary conductor lead temperature limited to +150°C.
5	GND	power_in	Output-side ground reference; the datasheet requires a 1 µF bypass capacitor between pins 8 and 5 and states the signal leads (pins 5 through 8) are electrically isolated from the primary conductor.
6	FILTER	passive	Filter pin to set the output bandwidth (80 kHz typ. with a 1 nF ceramic capacitor CF connected from FILTER to GND), replacing an external RC filter on VOUT.
7	VOUT	output	Ratiometric analog output voltage proportional to the input current, with zero-current level VDD/2 and a maximum output current of 10 mA source or sink; output capacitance load limited to 10 nF and resistive load at least 4.7 kΩ.
8	VDD	power_in	Supply voltage relative to GND, recommended 4.5 V to 5.5 V (absolute maximum 8.0 V), with a 1 µF bypass capacitor to pin 5 recommended.
