TDA8205

The TDA8205 is designed as nicam QPSK demodulator which is essentially divided into two signal processing sections. The first section handles all the NICAM signal acquisition, the QPSK demodulator and clock and data recovery circuits.

TDA8205 has many features. The first one is highly integrated two-chip solution for nicam demodulation. The second one is automatic dual standard demodulation. The third one is 40dB range AGC. The fourth one is single crystal operation. The fifth one is NICAM 728 data and clock recovery. The sixth one is low pass filter for PWM coded audio signals and J-17 de-emphasis. The seventh one is automatic FM mono selection by reverse sound switch function. The eighth one is versatile audio switching matrix. The ninth one is automatic mute function. That are all the main features.

Some absolute maximum ratings of TDA8205 have been concluded into several points as follow. The first one is about its supply voltage which would be 7V for Vdd and 15V for Vcc. 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 TDA8205. The first one is about its supply voltage range which would be min 4.75V and typ 5V and max 5.25V for Vdd. The second one is about its supply current which would be min 10mA and typ 18mA and max 42mA for Idd. 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.
