• Description: Tv Sound Am-demodulator And Audio Source Switch
• Manufacturer: NXP Semiconductors

Philips Semiconductors
Notes to the characteristics
1. In the power supply voltage range V
2. Start of gain control (low IF input signal) at 3 dB AF signal reduction at pin 6.
3. End of gain control (high IF input signal) at +1 dB AF signal expansion at pin 6.
4. This state is also valid for pin left open-circuit.
5. If a DC-plop of about maximum 100 mV is acceptable when switching from internal to external audio-signal or from
6. Measured with V
7. Dependent on value of AGC capacitor.
