SK25

The SK25 is a discrete Op-Amp that we developed as a replacement for the API* 2520.

The SK25 will give its best noise performances with high impedance sources like high ratio input transformers (1:4 and above).

Highlights

• Pin compatible with API 2520 and 99 DOA's
• For input transformers with a ratio of 1:4 and more
• 100% Class A with RL ≥ 600 Ω
• Low noise, high gain, low offset
• Very good stability
• Wide supply voltage range from +/-15V to +/-24V
• Rich quiescent current
• Short circuit protected output
• Available assembled or as a full kit (everything included)

What's in the kit?

Everything!

You bring the solder (use good quality solder, 1mm diameter max).

Difficulty level

The SK25 kit is not a kit for beginners because of the high density of components. It is recommended to people with some soldering experience.

Product Options

Assembled Product: If you prefer not to DIY, choose an Assembled product. It comes fully assembled, ready to use.
