Sparkos Labs DIP8 Discrete Opamps

Sparkos Labs has created a family of discrete opamps in an DIP8 package optimized for high-performance audio applications. These devices are drop-in replacements for many common, chip opamps and are uniquely compensated for trouble-free swapping into virtually any circuit.

Class-A biasing and high-current capability coupled with a proprietary compensation scheme requiring multiple NPO dielectric capacitors make these discrete opamps impossible to fabricate as a monolithic IC. These devices utilize matched transistor pairs encapsulated within a single device package for the input stage and internal current mirrors for excellent matching between devices.  Each device is fully specified, and is available as a single or dual discrete opamp.
