IC Datasheet Information

The IC TDA 7052 contains all of the necessary circuits, allowing us to connect an audio input signal and a speaker directly to it. The audio signal is connected to pin 2 of the input, while pin 3 is connected to the ground of the audio signal. Between pins 5 and 8, there is a speaker (8). This circuit is powered by a 6V DC source. The frequency response of this circuit is good, ranging from 20Hz to 20KHz. The supply voltage range of the IC TDA7052 is 3V to 18V, with a typical 6V DC. The maximum quiescent current is 8 mA. The TDA7052's voltage gain is set at 40 dB internally. The maximum 100 mV audio output may be obtained between pins 5 and 8, and the input impedance of this circuit is 100K.
