CA3140AMZ from RENESAS, in a SOIC-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	OFFSET NULL	passive	Offset null terminal for input offset voltage nulling.
2	INV. INPUT	input	Inverting input of the PMOS-input stage with very high input impedance.
3	NON-INV. INPUT	input	Non-inverting input of the PMOS-input stage, common-mode range extends down to 0.5V below the negative supply.
4	V-	power_in	Negative supply terminal (ground in single-supply use); total supply range is 4V to 36V.
5	OFFSET NULL	passive	Second offset null terminal for input offset voltage nulling.
6	OUTPUT	output	Bipolar output stage with built-in protection against short circuit to either supply rail or ground.
7	V+	power_in	Positive supply terminal; total supply range is 4V to 36V.
8	STROBE	input	Access terminal for a supplementary external capacitor for additional frequency roll-off.
