COS8052MR from COSINE, in a MSOP-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	OUT1	output	Output of amplifier A. The output voltage range extends to within millivolts of each supply rail (typ. 10 mV with RL=10 kΩ).
2	-IN1	input	Inverting input of amplifier A. Voltage range: -Vs -0.3 V to +Vs +0.3 V. Input terminals are diode-clamped to the supply rails; limit input current to 10 mA if signals swing beyond the rails.
3	+IN1	input	Non-inverting input of amplifier A. Same voltage range as -IN1 (-Vs -0.3 V to +Vs +0.3 V). Rail-to-rail input capability with common-mode range from -0.1 V to 5.6 V (Vs=5 V).
4	-Vs	power_in	Negative power supply or ground. If not tied to ground, bypass with a 0.1 µF capacitor placed as close to the pin as possible. Supports single-supply (0 V) or dual-supply (±1.25 V to ±2.25 V) operation.
5	+IN2	input	Non-inverting input of amplifier B. Same voltage range as -IN2 (-Vs -0.3 V to +Vs +0.3 V). Rail-to-rail input.
6	-IN2	input	Inverting input of amplifier B. Voltage range: -Vs -0.3 V to +Vs +0.3 V. Input terminals are diode-clamped to the supply rails.
7	OUT2	output	Output of amplifier B. Rail-to-rail output; short-circuit sourcing 100 mA, sinking 120 mA (typ.).
8	+Vs	power_in	Positive power supply, 2.5 V to 5.5 V (single-supply) or +1.25 V to +2.25 V (dual-supply). Bypass with a 0.1 µF ceramic capacitor placed as close to the pin as possible; a 2.2 µF tantalum can be added for better performance.
