Inside NE5532

Two low-noise bipolar input stages and compensated output paths.

Two Bipolar-input amplifier channels inside a compact NE5532 IC. A: positive 3, negative 2, output 1. B: positive 5, negative 6, output 7. Shared supplies 8 and 4.
Functional cutaway; internal compensation is included. External feedback sets the gain.

Input stages

The bipolar differential inputs offer low voltage noise, but draw bias current. The resulting error depends on source resistance and the feedback network.

Gain and compensation

Each channel has an internal voltage-gain path and frequency compensation.

Output drivers

Separate output drivers serve the two channels. Output swing depends on load and rail headroom; short-circuit protection is not a continuous-load rating.
