NJM2762
2-Channel Audio Limiter
GENERAL DESCRIPTION NJM2762 is a 2-channel audio limiter IC that will
consistently monitor the amplitude of the input audio signals and prevent them from exceeding a certain limit level.
NJM2762 will sense both input channels separately and when either input signals exceeded the preset limit level, it will reduce the gain of both channels together, such that the output is always balanced and limited to the desired level. The amount of attenuation will depend on the channel that has the worst overshoot condtion.
The limit level of NJM2762 can be adjustable by external resistor - making it is suitable for PC application and any audio products that required speaker protection at the back-end.
