No Preview Available ! TA7642 Radio IC The TA7642 is an AM radio IC in a TO92 package which requires very few external components to make a complete pocket radio. Features: • low operating voltage – down to 1.3V • low quiescent current – 0.2mA • very few external components required Maximum ratings: Parameters Supply voltage Operating temp. Storage temp. Min. -10 -55 Max. 6 60 150 Unit V °C °C Electrical Characteristics: Parameters Symbol Supply voltage Quiescent current Input resistance Maximum sensitivity Detector output voltage AGC Range VCC ICCQ RI SM VOD A Example circuit: Test conditions VI = 0 VOD = 3mV VI = 10mV Min. 1.2 0.14 - - 5 - Pin no. 1 2 3 Symbol Vss I/P O/P Desc. Gnd Input Output Typ. 1.3 0.20 3 600 15 30 Max. 1.6 0.30 - - 30 - Unit V mA MΩ µV mV dB The coil needs approximately 55 turns of 0.315 (30 SWG) of enamelled copper wire on a 100 x 10mm ferrite rod. A process of trial and error will help you achieve the optimum number of windings. 1 page
