NJM2774

Stereo Headphone Amplifier & Audio Line Amplifier IC

!GENERAL DESCRIPTION

The NJM2774 is a headphone amplifier and 2-channel

!PACKAGE

audio line amplifier IC.

Each amplifier has a fixed DC Gain. Therefore, it is

connectable directly to 3.3V operating device without input

coupling capacitor.

The headphone amplifier and one of audio line amplifier

(Amplifier 2) include Low-pass filter for PWM input signal.

Further, another audio line amplifier (Amplifier 3) corresponds

both single-end input and differential input.

NJM2774V

Also, it includes 3-circuit voltage detector and mute

transistor control circuit.

The NJM2774 is suitable for audio applications with a

headphone and audio line outputs.
