Hi team,

Why LM7705 can only output -0.232V?  How it works？

Thank you very much and looking forward to your reply.

    Hi Kevin,

    As per my understanding, this device has been designed in a way to provide fixed negative output to supply the negative bias to the amplifier. As this is an old device, I am not able to get detailed explanation on the functional block diagram. 

    Thanks!

    Best regards
