Buffer for TDA7266?

jaste · 1st January 2009, 03:09 PM

Hello! I´m building a little amp for my parents using the TDA7266. Can anyone recommend a nice op amp for a buffer with single supply of 12 volts? Been thinking about the NE 5532 but wanted to hear your opinion.

Thank you for your help!

it will work with the (bipolar) 5532.many outputstages of cdplayers use it.another ic is the lf353(jfet) with equal pinconnection -you can change it for listeningtests each other.
essential:the purity of voltagesupply,ic`s are sensitive to supply noise and so;e.g. two voltage regulators in series,one near by the pins of the ic..............kind regards........

Could someone maybe recomend a schematic for the NE 5532?

datasheets you can find on: datasheetcatalog.com
write in simply: 5532 -and there are all sheets.

or better write in: ne5532 and click : search

I was more thinking of a circuit where the ne 5532 was used. As an buffer that is.

here is a classical buffer amp(with optional volume control).most of the parts are free to choose.

you don't need a buffer!
