The TDA3843 is an integrated circuit from NXP Semiconductors that performs AM-sound demodulation for the L- and L'-standards in televisions. It features a wide operating supply voltage range, accepting either 5V to 8V or an alternative 12V supply.
Key electrical characteristics include a low power consumption of 200 mW at a 5V supply. The device incorporates an AC-coupled wideband IF-amplifier offering high dynamic ranges and reduced intermodulation. It also includes an in-phase wideband AM demodulator that does not require an external reference circuit. The TDA3843 provides reduced Total Harmonic Distortion (THD) figures, typically 1%, even for low AF frequencies, and a stabilizer circuit for ripple rejection and constant output signals.
This component is available in a 16-lead DIP package. All pins are ESD protected, ensuring robust handling and operation. The TDA3843 is suitable for applications requiring reliable AM sound demodulation in television systems adhering to L and L' standards.
