OPA2333HD from Texas Instruments, in a SOIC-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	OUT A	output	Analog output of channel A. Rail-to-rail output stage swings within 150 mV of the supply rails; short-circuit protected (one amplifier per package).
2	-IN A	input	Inverting analog input of channel A. High-impedance CMOS input with common-mode range extending 100 mV beyond both supply rails; internal ESD/diode clamps to V+ and V- (limit input current to <10 mA if signal exceeds rails by more than 0.3 V).
3	+IN A	input	Noninverting analog input of channel A. High-impedance CMOS input with common-mode range extending 100 mV beyond both supply rails; diode-clamped to the supplies.
4	V-	power_in	Negative (lowest) power-supply pin. Single-supply operation ties this to GND; total supply span (V+) - (V-) must be 1.8 V to 5.5 V. Also serves as the die backside potential.
5	+IN B	input	Noninverting analog input of channel B. High-impedance CMOS input with common-mode range extending 100 mV beyond both supply rails; diode-clamped to the supplies.
6	-IN B	input	Inverting analog input of channel B. High-impedance CMOS input with common-mode range extending 100 mV beyond both supply rails; diode-clamped to the supplies.
7	OUT B	output	Analog output of channel B. Rail-to-rail output stage swings within 150 mV of the supply rails; short-circuit protected (one amplifier per package).
8	V+	power_in	Positive (highest) power-supply pin. Accepts 1.8 V to 5.5 V above V- (single-supply) or ±0.9 V to ±2.75 V (split-supply). Bypass to V- with a 100 nF ceramic capacitor placed close to the pin.
