TA2030FNG

TA2030FNG TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA2030FNG TV / FM System F / E (1.5V USE) The TA2030FNG is a TV / FM system front end IC, which is developed for headphone radio in 1.5V use. It is built in FM F / E and TV F / E (japanese VHF band). Features Built−in FM F / E and TV F / E FM mode: 75~109MHz TV mode: 175~225MHz Suitable for combination with digital tuning system. Built−in power switch Built−in FM / TV switch Built−in IF amplifier Built−in OSC buffer circuit Improved inter−modulation characteristics by double balanced type mixer circuit. Supply current (VCC = 1.2V, Ta = 25°C) FM mode: ICC = 4.4mA (typ.) TV mode: ICC = 6.3mA (typ.) Operating supply voltage range (Ta = 25°C) VCC (opr) = 0.95~4V Weight: 0.09g (typ.) 1 2004-11-17 TA2030FNG Block Diagram 2 2004-11-17 TA2030FNG Terminal Explanation Terminal Voltage: Typical Terminal Voltage at no Signal with Test Circuit.
