NJM2781 Datasheet (ETC) - Monaural Microphone Amplifier

NJM2781, Monaural Microphone Amplifier

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 hand
