Orange DIP 8 based IC Dual Discrete OP-Amp Type

The Dual Discrete op-amp is specially designed for audio and is among the most musical sounding dual discrete op-amps out there. It is available in DIP 8 format and can be used in any CD player, DAC, or preamplifier that currently runs DIP 8 based IC dual op-amp types.

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. It can replace the following, 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 with our op-amp as with all discrete types, they do draw more current. Please refer to the spec sheet for details.

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. The spec-sheet shows a max +/- rail voltage of 18 volts.

All tests up until now have been conducted with this voltage along with +/-15 volts. As soon as we have test results using it on rails of +/-24 volts
