TDA1220B AM-FM QUALITY RADIO

TDA1220B AM-FM QUALITY RADIO The TDA1220B is a monolithic integrated circuit in a 16-lead dual in-line package. It is intended for quality receivers produced in large quantities. The functions incorporated are: AM SECTION – Preamplifier and double balanced mixer – One pin local oscillator – IF amplifier with internal AGC – Detector and audio preamplifier FM .

Features

  – Very constant characteristics (3V to 16V)
  – High sensitivity and low noise
  – Very low tweet ORDERING NUMBER : TDA 1220BK DIP-16 Plastic (0.25)
  – Sensitivity regulation facility (
*)
  – High recovered audio signal suited for stereo decoders and radio recorders
  – Very simple DC switching of AM-FM
  – Low current drain
  – AFC facility (
*) Maximum AM sensitivity can be reduced by means of a resistor (5 to 12KΩ) between pin 4 and ground. BLOCK DIAGRAM March 1993 1/18 TDA1220B ABSOLUTE MAXIMUM RATINGS Symbol Vs Ptot Top Tstg, Tj Supply voltage Total power dissipation at Tamb < 110°C Operating te.
