Hi team,
I'm looking for a solution that enables analog gain control with 60dB attenuation.
I see an application note below, like it but need more attenuation. DC voltage is preferred as control way than serial interface (ex:I2C) since a potentiometer is used with knob.

Can you suggest recommended solution?
Best regards,
