CA3140AMZ96 from RENESAS, 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	OFFSET_NULL	passive	Offset-null adjust terminal. Connect a potentiometer (typ ~18kΩ for CA3140A) between pins 1 and 5 with the wiper to V- (pin 4) to trim the input offset voltage to zero.
2	INV_INPUT	input	Inverting input (-) of the op-amp. High-impedance PMOS gate; input impedance ~1.5TΩ, input current ~10pA (typ, ±15V supply). Absolute input voltage limited to (V+ +8V) to (V- -0.5V).
3	NON-INV_INPUT	input	Non-inverting input (+) of the op-amp. High-impedance PMOS gate; common-mode range extends from ~V- -0.5V up to ~V+ -1.5V at ±15V (typ -15.5V to +12.5V).
4	V-	power_in	Negative supply rail (or ground in single-supply operation). Total supply voltage V+ to V- must not exceed 36V. Serves as the reference to which the output can swing to within ~0.13V in single-supply use.
5	OFFSET_NULL	passive	Second offset-null adjust terminal. Used with pin 1 and a potentiometer whose wiper returns to V- (pin 4) to trim V_IO. May alternatively be used with pin 4 for offset adjustment.
6	OUTPUT	output	Bipolar op-amp output. Short-circuit protected to either supply rail. Typical output swing +13V/-14.4V at ±15V into 2kΩ; source/sink short-circuit currents ~40mA/18mA.
7	V+	power_in	Positive supply rail. Operating supply range 4V to 36V (single or dual). Typical supply current 4mA at ±15V (6mA max).
8	STROBE	input	Strobe/output-disable terminal. Sinking ~220µA from pin 8 to pin 4 (V-) forces the output to swing low, allowing the amplifier to be gated off. Also provides an access point for adding an external compensation capacitor if additional frequency roll-off is desired.
