TDA7000 is a monolithic integrated circuit for mono FM portable radios, where a minimum on peripheral components is important (small dimensions and low costs).
The TDA7000 is a monolithic FM radio IC designed for portable radios where low component count and cost are important. It includes an FLL system, RF input stage, mixer, local oscillator, IF amplifier/limiter, phase demodulator, mute detector and mute switch.
The datasheet lists electrical parameters such as supply voltage range, current consumption, frequency ranges, sensitivity, distortion and noise figures, as well as package dimensions and soldering guidelines.
| Supply voltage range (pin 5) | 2.7 to 10 V |
|---|---|
| Typical supply current at Vp=4.5 V | 8 mA |
| RF input frequency range | 1.5 to 110 MHz |
| Sensitivity (EMF) –3 dB limiting, mute disabled | 1.5 pV |
| Signal handling (EMF) typical | 200 mV |
| Signal‑to‑noise ratio | 60 dB |
The device operates from 2.7 V up to 10 V on pin 5.
Typical supply current is 8 mA when Vp is 4.5 V.
It accepts RF input frequencies from 1.5 MHz to 110 MHz.
The sensitivity is 1.5 pV EMF for –3 dB limiting when mute is disabled.
