Title: Notes on Audio Op-Amps
Post by: rascal101 on Jul 19, 2005 at 10:13 AM
Some listening tests were conducted on the ff: op-amps:

OPA2107, OPA602, AD825, AD744, AD797, LT1028, LT1115, LT1122, AD826, NE5534, NE5532,
OP275, LF356, and LM386

and the results show that the OPA627 and AD843 come out on top. Below is the link on the full
review. It also comes with a steep price (literally).

Ako rin ADI din ako. Wala na nga palang Burr Brown at binili na sila ng TI.

Date nga pala akong Test/Product Engineer sa Analog Devices kaya lang hindi ko alam na pang audio iyung mga op-amps. May hawak din akong op-amps mostly using BiFET technology. Mayroon din akong hawak ADC/DAC na pang audio. Alam ko iyung mga op-amps pang test equipment lang kasi panay precision op-amps iyung mga tine-test namin.

Sir 2ny,

Am willing to lend you my differential amp samples (some) for the op-amps. That way we can validate the sound of these chips ...

I have a pair of brown dog adapters on stock (last ones).

The minimum purchase from the Internet is 5 peices. These are left-overs from my op-amp rolling "adventures" using AD8066.

Text to 0917 853 4185 if you are interested to buy. I'm giving this to you first, but if you will not be interested then I will post it in the Buy and Sell section.



Thanks.
