The MT1120 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 MT1120
integrates two true-RMS power
detectors and two uncommitted
op-amps in order to realize an AGC
function for AM and FM by simply
adding external PIN diodes. The
thresholds of the AM and FM AGC
function are variable and can be set
according to the application
requirements. The on-chip 2.55V
temperature compensated reference
generator and high output voltage
op-amp combine to form a low-cost,
reliable, automotive-capable power
supply which can be directly derived
from the car battery.
