Monaural Microphone Amplifier
I GENERAL DESCRIPTION
NJM2781 is a monaural microphone amplifier IC with a standby
function, and can vary a voltage gain by adjusting an external
resistor.
Since the NJM2781 operates with a low voltage range of +2.7V to
+4.5V and is available in tiny packages of TVSP8 and SSOP8, it is
ideally suited for portable and handheld components.
