K1803 Mono Preamp

Can this be run from a 5 volt supply? I need to amplify uV signals to use a dynamic mic in place of an electret mic.

Hi @bges,

Unfortunately, the K1803 needs at least 10V to be operational.
You can use the VMA402 to boost your 5V to 10V, or use a 5V based amplifier (like the MM210) instead of the K1803.

Kind regards,
