It replaces 6-pin, 1-inch square op amps of the API 2520 and Jensen 990 type found in microphone preamps, lunchbox modules, compressors, EQs, and mixing consoles.\u003c\/p\u003e\n\u003cp\u003eThe design is fully discrete, with modern high-performance transistors, two-pole compensation, and 165 dB of open-loop gain at 100 Hz. This delivers an amplifier that is sonically transparent - \"a piece of wire with gain\" - with fast transients, low distortion, and a Class A output current of ±32 mA.\u003c\/p\u003e\n\u003cp\u003eMany op amps in this class were built in the 1970s using the technology of the time. SS2590 is a modern replacement that is also unity-gain stable and can drive 75-ohm loads at full output.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNOTE!
