... The U2861B is an alignment-free FM sound IF demodulator for all TV standards from 4.5 MHz up to 6.5 MHz (standard M, N, B/G, I, D/K). The circuit includes two switch- able audio inputs and volume control. With a supply voltage of 5V, the U2861B is suitable for TV, VCR and Multimedia applications. ...

... The second audio switch (pin 11) has inputs for the audio signal from switch 1 and the external AF2 signal at pin 10. The switched AF signal is fed to volume control. The output voltage can be controlled voltage at pin 9. 2.4 Internal Voltage Stabilizer The internal band-gap reference ensures constant performance independent of supply voltage and temperature.
