Objective specification
Quasi split-sound circuit and AM demodulator
Features
- Power supply from 5 V (200 mW) to 8 V source also an alternative 12 V source (12 V not for TDA3845T)
- Gain controlled wideband IF amplifier (AC coupled with three stages)
- High precision internal 90° phase shifter for quadrature demodulator
- Amplitude detector for gain control which operates as a peak detector for FM sound and as a mean level detector for AM sound (switchable)
- In-phase wideband synchronous...
