[Outline]
This is an I
2C bus controlled audio switch IC developed for TVs, PDP and projection TVs. It provides 11 inputs and 3 outputs of audio singals (R/L).
Design of the input switch block can be simplified by using this IC with MM1630 (video switch IC).
[Features]
1. |
The desired input can be selected for each of the 3 independent output lines. |
2. |
Wide dynamic range (3Vrms) |
3. |
Serial by I2C bus |
4. |
Forced mute enabled by an external pin |
5. |
Includes a power-save function |
6. |
I2C bus lines maintain high impedance during power-off. |
7. |
No output waveform folding with 7.1Vrms input |
