Hello.

We are looking for alternative amplifier to replace a device from ONSemi LA74309FA.

What the AB-class mono amplifier with internal automatic level control can we propose for this case?

Thank you.

Hi Slava,

Could you please provide more details about how the automatic level control works on this part? I'm not sure if we have an exact replacement.
You could take a look at our mic preamps, we have some PGA devices with gain control: Microphone Preamplifiers | Products | Audio | TI.com

Hello Ivan,

automatic level control works like automatic gain control.

Do we have a microphone amp with built-in AGC and without digital interfaces?

Thank you for the link, but I can't find the required amp type from available devices.

Slava, I don't think there is an exact replacement based on your requirements.
