-
Description
The NJM2775A is a pre&power amplifier with ALC designed for micro and compact cassette recorders. It 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 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.
