The MT1119 is an advanced, low power, 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. The threshold of the FM AGC function is variable and can be set according to the application requirements. The on chip 2.5V temperature compensated reference generator and high output voltage op-amp combine to form a ow-cost, reliable, automotive capable power supply which can be directly derived from the car battery.
