The LA1140 is a high-frequency middle-amplifier IC which is mainly used for radio middle-frequency signal processing in many kinds of audio equipments.
The LA1140 IC has internal middle amplifier, amplitude limiting, wave detecting, output signal voltage level indicator and other functions. Its sensitivity of amplitude limiting is high and its gain and frequency can be controlled automatically. Its automatical frequency control output can complete the noise elimination by clamping and it would vary in proportion with the size of the input signal.
The picture shows the LA1140.
