Abstract: This speaker protection circuit includes: a voltage comparator that compares a voltage of a reference bias terminal of an amplifying circuit constituting a BTL amplifying device with a preset threshold voltage; and first and second switches for switching between a mode of supplying an electric current to each of two power amplifying circuits and a mode of cutting off the electric current. When the voltage of the reference bias terminal is lower than the threshold voltage, based on an output level of the voltage comparator, at least one of the first and second switches is turned off to cut off a current supply to each of the power amplifying circuits so that driving of a speaker by the power amplifying circuits is halted. Thus, it is possible to suppress, using a relatively simple configuration, an offset current generated in a speaker due to an abnormality of the voltage of a reference bias terminal.

Abstract: An AGC circuit of the present invention includes a first up/down counter for converting the amount of change in an output voltage higher than a threshold voltage into a count value and controlling a gain of a variable gain amplifier circuit and a second up/down counter to which a reference clock having a lower frequency than that of a reference clock supplied to the first up/down counter is supplied. Count values of the first and second up/down counters are D/A-converted and then compared with each other by a voltage comparator. An up/down count of the first up/down counter is controlled based on a comparison result and the gain of the variable gain amplifier circuit is controlled using only a signal based on the count value of the first up/down counter, thereby suppressing distortion of an output waveform and the generation of a frequency signal which is not originally input.

Abstract: An AGC circuit, which does not require any signal integration circuit comprised of a capacitor and a resistor, is provided. To achieve the above object, when amplifying or attenuating input signal by a variable gain control circuit controlled by the gain control voltage, output signal of the variable gain amplifier circuit is rectified by a rectification circuit, the output signal of the rectification circuit is compared to an arbitrary set voltage by a voltage comparator. The up-count operation and the down-count operation of the up/down counter is controlled to changeover by the output signal of the voltage comparator, and a voltage corresponding to the count value of the up/down counter is output from the D/A conversion circuit. Thus, gain control voltage corresponding to the voltage output from the D/A conversion circuit is supplied to the variable gain amplifier circuit.
