■ GENERAL DESCRIPTION ■
■■
■ PACKAGE OUTLINE
The NJM2755 is 4 Input / 1 Output Stereo Audio Selector.
The NJM2755 consists of switches and buffer operational
amplifiers.
Based on the internal switch op-amp technology, the
NJM2755 features lower output noise, lower distortion and
higher channel separation than the general Multiplexers or
Analogue Switches.
The NJM2755 contains compatibility with NJM2752(2in-1out
SW),NJM2753(3in-1out SW).
