    Hello sir,
    I'd already have an TDA7297 IC from
    old samsung TV.
    Can I use it anyway to build an Amplifier?
    Is the program were same?

    Hello,

    Did you read the link I gave you?
    It contains a schematic and the datasheet of the chip.

    Yes I did.
    But I don't have any application to set the ic with this data program.
    So may i know what the program of this ic will same other old ones..
    If it's not same i'll forget about This ic.
    Coz In our country, it is difficult to Insert the program to IC.

    Hello,

    There is nothing to program the chip.
    It is a bare audio amplifier:

    It's ok sir.
    I really wanna know is this Answer.
    I thought it is a IC it needs a program.
    I waek in English skills.
    Thz u for ur answer.
    Sorry for annoy.

    Hello,

    You do not annoy me. We are here to learn from each other.
    Did you see my signature?

    When you do ask questions, you may look stupid.

    I have seen the same mistake in people 40 years old. They think everything needs to be programmed.
    I built a guitar amplifier for a friend. He asked me if it would need its programming updated regularly.
    I didn't know what to say. I don't program small amplifiers. They are too simple.
    That is what you have in the TDA chip. It is a simple amplifier.

    OK,
    I wanna talk u about this what u say mistake.
    The mistake in our country.
    From General Technological Institude (GTI)
    in our country, the teachers say Datasheet means An IC that needs a program..
    Lolll....
    I don't mind whatever u say about my mistake.
    My careless understanding.
    What do u think about our GTI?
    It's not a good one for students...
    Thz u...

    A datasheet is information about the IC, the Basic being:-

    What it does,
    What are the pin connections,
    What is the Normal Voltage required, the Maximum and Minimum Voltages Permitted,
    What is the Maximum Current it can give ( or Watts it can deliver)
    The maximum Operating Temperature,
    A typical Schematic for its Application.

    The datasheet will normally have much more information, but at this stage, you need be concerned
    only with the above....

    Wrong.
    All chips and transistors have datasheets.
    Even resistors have datasheets.
    How can you program a resistor?
    LOL!

    No I don´t mind anything about what u say.
    Coz, I´m just saying about a mistake what u say wrong. R u ok?
    I´d already know about my mistake because of our Administrator ,Bertus.
    So, u r right, r u ok?
    I´m not saying an antonym.
    You r right.
