FM IF Amplifier with Demodulator for Radio Receivers
FM IF amplifier for radio sets with 8-stage amplifier and symmetrical coincidence demodulator. The TDA1047 additionally offers provisions for feeding an amplitude indicator and either positive or negative mono-stereo voltage as wel as an AFT output (push-pull current output) with automatic switch-off. The include squelch can be adjusted within an input signal range of more than 40dB and depends on detuning.
Features
* Excellent limiting qualities
* Excellent frequency stability of demodulator characteristic
* Large range of operating voltage between 4 and 18V
* Low current consumption
* Externally adjustable squelch
* Few external components
* Operating range:
- Supply voltage: 4 to 18V
- Frequency: + to 15 MHz
- Ambient temperature: -25 to +85C
