CC6920BSO-30A 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 + input. One terminal of the internal low-resistance (~0.9 mΩ) copper primary conductor. Pins 1 and 2 are internally connected and should be tied together on the PCB to carry the sensed current (up to ±30 A continuous for this variant).
2	IP+	passive	Current sampled + input. Internally connected to pin 1; both pins form the positive terminal of the isolated primary copper conduction path.
3	IP-	passive	Current sampled - input. One terminal of the internal low-resistance copper primary conductor. Pins 3 and 4 are internally connected and should be tied together on the PCB.
4	IP-	passive	Current sampled - input. Internally connected to pin 3; both pins form the negative terminal of the isolated primary copper conduction path.
5	GND	power_in	Signal-side ground reference for the secondary circuitry. All VOUT and VZCR voltages are referenced to this pin.
6	VZCR	output	Zero current reference signal output. Nominally VCC/2 (≈1.65 V at VCC=3.3 V), used as a ratiometric zero-current baseline for downstream ADCs or differential amplifiers. Source current up to 400 µA; sink current up to 3 mA.
7	OUT	output	Analog voltage output proportional to sensed primary current. VOUT = VCC/2 + 0.044 × IP (V) for the 30 A variant. Linear range 0.33-2.97 V at VCC=3.3 V; source 6 mA / sink 30 mA max.
8	VCC	power_in	Signal-side supply voltage input. Operating range 3.0-3.6 V (typ 3.3 V); typical ICC = 20 mA (25 mA max) with OUT floating. Absolute max 7 V. Decouple with 0.1 µF to GND close to pin.
