LT1994CMS8#TRPBF from Analog Devices, 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	IN-	input	Inverting input of the amplifier; keep stray capacitance to a minimum with short PCB connections (pin function text lists IN+ as Pin 1 and IN- as Pin 8, but the MS8 pin diagram shows IN- at pin 1).
2	VOCM	input	Output common mode reference voltage with approximately 40k Thevenin resistance to a mid-supply default; sets the output common mode level and should be bypassed with at least 0.1µF unless tied to a low impedance ground plane.
3	V+	power_in	Positive power supply pin, bypassed to V- with 1µF and 0.1µF ceramic capacitors; total supply (V+ to V-) is up to 12.6V.
4	OUT+	output	Positive output pin, drives approximately 100Ω to ground with short-circuit current limit up to ±85mA and is designed for 25pF load capacitance.
5	OUT-	output	Negative output pin, drives approximately 100Ω to ground with short-circuit current limit up to ±85mA and is designed for 25pF load capacitance.
6	V-	power_in	Negative power supply pin, tied directly to a low impedance ground plane in single-supply applications.
7	SHDN	input	Shutdown input: floating or tied to V+ is normal operation, and pulled a minimum of 2.1V below V+ enters low power shutdown (internal 120k pull-up).
8	IN+	input	Noninverting input of the amplifier; keep stray capacitance to a minimum with short PCB connections (pin function text lists IN- as Pin 8 and IN+ as Pin 1, but the MS8 pin diagram shows IN+ at pin 8).
