RF/IF circuit for AM/FM radio

GENERAL DESCRIPTION\nThe TEA5570 is a monolithic integrated radio circuit for use in portable receivers and clock radios. The IC is also applicable to mains-fed AM and AM/FM receivers and car radio-receivers. Apart from the AM/FM switch function the IC incorporates for AM a double balanced mixer, 'o • Simple d.c. switching for AM to FM by only one d.c. contact to ground (no switch contacts in the i.f. channel, a.f. or level detector outputs)\n• AM and FM gain control\n• Low current consumption (Itot = 6 mA)\n• Low voltage operation (VP= 2,7 to 9 V)\n• Ability to handle large AM signals; good i.;
