ORANGE-DD Dual Discrete Op-amp

Orange's Dual Discrete Op-Amp has been specifically designed for one purpose: natural, clean audio for musical performances. Designed to fit an industry standard DIP 8 socket, it can be used in any CD player, DAC, or preamplifier that currently runs DIP-8 dual op-amps

The overall soundstage and transient detail will be greatly improved when used in pretty much all audio equipment that it can physically be fitted to. It has a very low noise Jfet front end so it can run with input impedances above 1M Ohms if needed.

This op amp has been tested as a replacement for the following parts, provided the equipment it's being used in has 22mm of height clearance and 5mm side clearance (per side):

OPA2604 | OPA2134 | TL072 | NE5532 | LM4562 | OP275 | OP285

Please check that the PSU can supply the extra current needed, especially if replacing more than one existing IC op-amp.

The Orange Dual Discrete Op-Amp is unity gain stable. When using it in new designs where gain (inverting or non inverting) is being added, a feedback loop bypass capacitor of 15pf is all that's needed to completely stabilise it.
