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.

TEA5591A General Description

The TEA5591A is a 24-pin integrated radio circuit, derived from the TEA5591 and is designed for use in AM/FM portable radios and clock radios. The TEA5591A differs from the TEA5591 in that it has:
Separate IF input pins for AM and FM
A split-up AM-IF stage (for distributed selectivity)
An LED driver indicator

The main advantage of the TEA5591A is its ability to operate over a wide range of supply voltages (1.8 to 15 V) without any loss of performance.The AM circuit incorporates:
A double balance mixer
A 'one-pin' oscillator with amplitude control operating in the 0.6 to 30 MHz frequency range
A split-up IF amplifier
A detector
An AGC circuit which controls the IF amplifier and mixer.

The FM circuit incorporates:
An RF input amplifier
A double balanced mixer
A 'one-pin' oscillator
Two IF amplifiers (for distributed selectivity)
A quadrature demodulator for a ceramic filter
Internal AFC
