CC6920SO-10A from Cross chip, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	IP+	passive	Current Sampled + (primary conductor input). Pins 1 and 2 are internally tied together and form one terminal of the isolated primary copper conductor (~0.9 mΩ). Positive current flow from IP+ (pins 1-2) to IP- (pins 3-4) produces a positive sensor output.
2	IP+	passive	Current Sampled + (primary conductor input). Internally connected to pin 1 to form the positive terminal of the primary current path. Continuous current rating 40 A; peak 100 A (3 s).
3	IP-	passive	Current Sampled - (primary conductor return). Pins 3 and 4 are internally tied together and form the return terminal of the isolated primary copper conductor.
4	IP-	passive	Current Sampled - (primary conductor return). Internally connected to pin 3 to form the negative terminal of the primary current path.
5	GND	power_in	Signal ground reference for the secondary (signal) side of the isolation barrier. All output voltages (OUT, VZCR) and VCC are referenced to this pin.
6	VZCR	output	Zero-current reference signal output (VCC/2). Provides a ratiometric mid-supply reference for downstream signal-conditioning circuits. Source current ≤400 µA, sink current ≤3 mA; recommend reserving ≥0.3 mA in design.
7	OUT	output	Analog voltage output proportional to the sensed primary current. VOUT = VCC/2 + 0.200 × IP(A) for the -10A variant (200 mV/A sensitivity). Guaranteed linear range 0.5 V to 4.5 V at VCC = 5 V; drives up to 6 mA source / 30 mA sink into a load of ≥1.5 kΩ and ≤1 nF.
8	VCC	power_in	Power supply for the signal side of the chip. Recommended operating range 4.5 V to 5.5 V; absolute max 7 V. Typical supply current 20 mA. Decouple with 0.1 µF to GND close to the pin.
