TDA8204

The TDA8204 is designed as nicam decoder which performs two main functions, first one is NICAM decoding, second one is audio signal recovery (DAC) conbined with audio signal switching (matrix). An I2s output is provided for digital audio when required and all functions of both the TDA8204 and the TDA8205 are accessed via an on-chip I2c bus interface.

TDA8204 has many features. The first one is highly integrated two-chip solution for nicam demodulation. The second one is data and sound recovery according to EBU SPB 424 specifications. The third one is I2s interface for digital audio purposes. The fourth one is 4 times up sampling digital filter and noise shaper. The fifth one is I2c interface for microcontroller software drive. The sixth one is pay TV application capabilities. The seventh one is automatic error monitoring. That are all the main features.

Some absolute maximum ratings about TDA8204 have been concluded into several points as follow. The first one is about its supply voltage which would be 7V. The second one is about its total power dissipation which would be 1.2W. The third one is about its operating temperature range which would be from 0°C to +70°C. The fourth one is about its storage temperature range which would be from -20°C to +150°C. The fifth one is about its thermal resistance junction to ambient which would be max 67°C/W.

Also some electrical characteristics about TDA8204. The first one is about its supply voltage range which would be min 4.75V and typ 5V and max 5.25V. The second one is about its supply current which would be min 30mA and typ 60mA and max 92mA. The third one is about its low output voltage which would be max 0.4V. The fourth one is about its high output voltage which would be min 0.7Vdd. And so on. For more information please contact us.
