MT1119 AUTOMOTIVE AM/FM ANTENNA AMPLIFIER SUBSYSTEM

   The MT1119 is an advanced, lowpower, highly integrated single-chip amplifier IC specifically designed for automotive AM/FM antenna systems requiring low noise and very low distortion. Additionally, the MT1119 has an integrated true-RMS power detector and an uncommitted op-amp in order to realize an AGC function for FM by simply adding external PIN diodes.

FEATURES
• AM input frequency range
   0.15 MHz to 30 MHz supports
   AM, DRM and HD Radio
   standards in the longwave,
   midwave and shortwave band
• FM input frequency range
   76 MHz to 162.4 MHz
   supports FM and HD Radio
   standards in the FM and
   weather band
• Fully integrated amplifiers for
   AM and FM
• Fully integrated RMS level
   detector and general purpose
   op-amp (PIN-diode drivers)
   for easy implementation of
   AGC function for FM
• On-chip reference voltage
   generator and high output
   voltage op-amp builds a
   reliable low-cost voltage
   regulator function
• Low noise
