THS4151IDGK from Texas Instruments, in a MSOP-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	VIN−	power_in	Inverting input of the fully differential amplifier; absolute maximum differential input voltage is ±6 V and input voltage is limited to ±VCC.
2	VOCM	input	Output common-mode voltage input that sets the common-mode level of the differential outputs VOUT+ and VOUT−.
3	VCC+	power_in	Positive supply pin; the datasheet gives VCC = 5 V single supply to ±15 V dual supply, with absolute maximum supply voltage ±16.5 V.
4	VOUT+	output	Non-inverting differential output; absolute maximum output current is 150 mA.
5	VOUT−	output	Inverting differential output; absolute maximum output current is 150 mA.
6	VCC−	power_in	Negative supply pin, used with VCC+ for dual-supply operation within the ±16.5 V absolute maximum supply rating.
7	NC	unconnected	No internal connection on the THS4151; the PD shutdown pin on the THS4150 is not present on this device.
8	VIN+	power_in	Non-inverting input of the fully differential amplifier; input voltage is limited to ±VCC.
