AM/FM radio receiver circuit
TEA5591
GENERAL DESCRIPTION
The TEA5591 is an integrated radio circuit which is designed for use in portable receivers and clock radios. The IC is
also applicable to mains-fed AM an AM/FM receivers and car radio-receivers. The main advantage of this IC is its ability
to operate over a wide range of supply voltages without loss of performance. The AM circuit incorporates a balanced
mixer and a ‘one-pin’ oscillator, which operates in the 0.6 MHz to 30 MHz frequency range, with amplitude control. The
circuit also includes an IF amplifier, a detector and an AGC circuit which controls the IF amplifier and the mixer. The FM
circuit incorporates an RF amplifier, a balanced mixer and a ‘one-pin’ oscillator together with two AC coupled IF amplifiers
(with distributed selectivity), a quadrature demodulator for the ceramic filter and internal AFC.
Features
·
DC AM/FM switch facility
·
Three internal separate stabilizers to enable operation over a wide range of supply voltages (1.8 to 15 V)
·
All pins (except pin 9) are ESD protected.
