TEA5711 AM/FM radio circuit

This AM/FM radio use the TEA5711 IC which is a high performance Bimos IC for use in AM/FM stereo radios with all necessary functions are integrated .
Using TEA5711 circuit we can make an simple and compact AM/FM radio using few external components .
Main features of TEA5711 circuit are : wide supply voltage range: 1.8 or 2.1 to 12 V , Low current consumption: 15 mA at AM, 16 mA at FM , High selectivity with distributed IF gain , LED driver for stereo indication , High input sensitivity: 1.6 mV/m (AM), 2.0 mV (FM) for 26 dB S/N , Good strong signal behavior (10 V/m at AM,500 mV at FM) , Low output distortion ( 0.8% at AM, 0.3% at FM ) .
The AM circuit incorporates a double balanced mixer, a one pin low-voltage oscillator (up to 30 MHz) a field-strength indicator output and is designed for distributed selectivity.
The FM circuit incorporates a tuned RF stage, a double balanced mixer, a one-pin oscillator, a field-strength indicator output and is designed for distributed IF ceramic filters.
The PLL stereo decoder incorporates a signal dependent stereo circuit, a soft-mute circuit and a stereo indicator LED driver.
The TEA5711 incorporates internal stabilized power supplies. The maximum supply voltage is 12 V, the minimum voltage can go down temporarily to 1.8 V without any loss in performance.
The TEA5711 AM/FM radio circuit from this schematic works from 522 to 1611 kHz AM and 87.5 to 108 MHz FM.
For AF amplifier is used the TDA7050T circuit .
