VCA810AIDR 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	+In	input	Noninverting analog input to the differential input stage. High-impedance input; common-mode range set by ±VS rails.
2	GND	power_in	Ground reference. Serves as the 0-V reference for the gain-control pin (VC) and the single-ended output.
3	VC	input	Gain control input. High-impedance analog input; 0 V => -40 dB, -2 V => +40 dB (40 dB/V slope). Voltages above ground attenuate the signal path to > 80 dB.
4	NC	unconnected	No internal connection. Leave floating or tie to ground per layout preference.
5	VOUT	output	Single-ended output referenced to GND. ±1.7-V output swing, ±60-mA drive capability, capable of driving doubly-terminated 50-Ω lines.
6	+VS	power_in	Positive supply rail. Nominal +5 V; operating range +4 V to +5.5 V (absolute max ±6.5 V total). Bypass with local decoupling capacitors.
7	-VS	power_in	Negative supply rail. Nominal -5 V; operating range -4 V to -5.5 V (absolute max ±6.5 V total). Bypass with local decoupling capacitors.
8	-In	input	Inverting analog input to the differential input stage. High-impedance input; common-mode range set by ±VS rails.
