Description

The NJM2775A is a pre&power amplifier with ALC designed for micro and compact cassette recorders. NJM2775A contains pre-amplifier, ALC circuit, power amplifiers, and ripple filter. The pre-amplifier amplifies the signal come from magnetic head. The ALC circuit limits the input signal to optimize level in recording. The power amplifiers NJM2775A drive a speaker in play back and the magnetic head in recording. The ripple filter stabilizing the supply voltage to the internal pre-amplifier and an external condenser microphone.


The NJM2775A improves high output power compared with the NJM2128.

NJM2775A is suitable for portable tape recorder, and other portable playing back and recording recorder items.
