TDA3843 Description

Short technical summary and product information.

The TDA3843 from NXP Semiconductors is an integrated circuit designed to perform AM-sound demodulation for television broadcasting standards L and L'. This component features a wideband IF-amplifier with high dynamic range and reduced intermodulation, along with an in-phase wideband AM demodulator that does not require an external reference circuit.

 

Key electrical specifications include a supply voltage range of 4.5V to 8.8V (pin 14) and 10.8V to 13.2V (pin 11). It offers a low power consumption of typically 200 mW at a 5V supply. The device provides a typical AF output signal of 550 mV (RMS) and a signal-plus-weighted-noise to weighted-noise ratio of 50 dB (CCIR 468-3).

 

The TDA3843 is housed in a 16-lead DIL package and supports through-hole mounting. It operates within an ambient temperature range of 0°C to 70°C. The circuit includes a stabilizer for ripple rejection and constant output signals, and all pins are ESD protected.
