Description
General part information
ATR4251C Series
Integrated low-noise AM/FM antenna amplifier with automatic gain control. Built on BiCMOS2S technology, it is designed for automobile applications and is suitable for windshield and roof antennas. The device compensates for cable losses between the antenna (for example, a windshield, roof, or bumper antenna) and the car radio, which may be located away from the antenna.
