OPA828IDR 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	NC	unconnected	No internal connection. Can be left floating or tied to ground.
2	-IN	input	Inverting (negative) op-amp input. High-impedance JFET input (Z_ID ~ 10^12 ohm
3	+IN	input	Noninverting (positive) op-amp input. High-impedance JFET input (Z_ICM ~ 10^12 ohm
4	V-	power_in	Negative (lowest) power supply rail. Total supply (V+)-(V-) up to 36 V (dual-supply +/-4 V to +/-18 V, or 8 V to 36 V single supply). Absolute max 40 V.
5	NC	unconnected	No internal connection. Can be left floating or tied to ground.
6	OUT	output	Op-amp output. Short-circuit current continuous into a short to ground (one amplifier per package). 45-MHz GBW, 150 V/us slew rate.
7	V+	power_in	Positive (highest) power supply rail. Nominal supply current ~5.5 mA/channel. Operating supply range 8 V to 36 V single or +/-4 V to +/-18 V dual.
8	NC	unconnected	No internal connection. Can be left floating or tied to ground.
