tba450 IC data?
Hi all,
I'm trying to repair an old radio receiver, it has a missing IC, from the schematic this should be a TBA 450, but I haven't been able to find any data on this IC. Does anyone have a datasheet or at least a pinout of this IC? Any cross-reference? Thanks in advance Frank IZ8DWF |

Does anyone have a datasheet or at least a pinout of this IC? It's not much, and it's in Polish ... http://datasheets.pl/T/TBA/TBA450.pdf That said, it doesn't look like this IC belongs in a radio. OTOH, my vrt databook refers to the TBA450(N)(Q) as a stereo decoder in a 16-pin DIP/QIP package. Perhaps Philips and Siemens used the same number for different ICs??? FWIW, there are some possible hits he http://www.google.com/search?q=tba45...3Apdf+st ereo In fact there is a TBA450 stereo decoder in the circuit diagram at the bottom left corner of page 3: http://marchal.jean.free.fr/Schemas/Dual/KA215.pdf - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |

Thanks in advance Frank IZ8DWF I got one hit at http://www.datasheetarchive.com/, which said it is a Infineon Technologies Single-Channel Audio Power-Output Amplifier. No datasheet. PlainBill |

OTOH, my vrt databook refers to the TBA450(N)(Q) as a stereo decoder in a 16-pin DIP/QIP package. Perhaps Philips and Siemens used the same number for different ICs??? it is definitely what's missing in the receiver. I guess it doesn't even have an equivalent. Thanks Frank IZ8DWF |

Thanks Frank IZ8DWF Telefunken also used TBA... |
