OP07DM from HGSEMI, in a SOP-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	Offset Null 1	passive	Input offset voltage nulling terminal 1. Connect a 20kΩ potentiometer between pins 1 and 8, with the wiper tied to V_CC+ to trim residual input offset voltage to zero.
2	Inverting Input	input	Inverting (-) analog input of the op-amp. Differential input voltage rating ±30V, common-mode range typically ±13.5V; differential input resistance 33MΩ.
3	Non-inverting Input	input	Non-inverting (+) analog input of the op-amp. Differential input voltage rating ±30V, common-mode range typically ±13.5V; differential input resistance 33MΩ.
4	VCC-	power_in	Negative supply rail. Operating range ±3V to ±16V (i.e. -3V to -16V referenced to VCC+). Typical no-load supply current 2.7mA (5mA max).
5	N.C.	unconnected	No internal connection. Leave floating or optionally tie to a stable potential; do not use as a routing via.
6	Output	output	Op-amp output. Swings typically ±13V into 10kΩ and ±12.8V into 2kΩ; open-loop output resistance 60Ω; slew rate 0.17V/µs; gain-bandwidth product 0.5MHz.
7	VCC+	power_in	Positive supply rail. Operating range ±3V to ±16V; also serves as the wiper reference for the external offset-null potentiometer connected between pins 1 and 8.
8	Offset Null 2	passive	Input offset voltage nulling terminal 2. Connect a 20kΩ potentiometer between pins 1 and 8, with the wiper tied to V_CC+ to null residual input offset voltage.
