Bowood Electronics Ltd 7 Bakewell Road, Baslow, Derbyshire. DE45 1RE Telephone: 01246 583777 E-mail: [email protected] TDA7000 FM Radio IC Order code: TDA130 The TDA7000 is a monolithic integrated circuit for mono FM portable radios. The IC has an FLL (Frequency-Locked-Loop) system with an intermediate frequency of 70 kHz. The i.f. selectivity is obtained by active RC filters. The only function which needs alignment is the resonant circuit for the oscillator, thus selecting the reception frequency. Spurious reception is avoided by means of a mute circuit, which also eliminates too noisy input signals. Special precautions are taken to meet the radiation requirements. The TDA7000 includes the following functions: • R.F. input stage • I.F. amplifier/limiter • Mixer • Phase demodulator • Local oscillator • Mute detector • Mute switch Specifications Supply voltage range Supply current at VP=4.5V R. F. input frequency range Sensitivity for –3dB limiting (e.m.f. voltage) (source impedance: 75Ω; mute disabled) Signal handling (e.m.f. voltage) (source impedance: 75Ω) A. F. output voltage at RL = 22kΩ VP 2.7V to 10V IP typ. 8mA frf 1.5 to 110 MHz EMF typ. 1.5µV EMF typ. 200mV Vo typ. 75mV Registered in England. Number 4036394 Directors: Mr W.R.C. Outram, Mr B.R.
