Inside MCP6022

Two CMOS input stages, compensated voltage gain and rail-to-rail output drivers.

Two CMOS-input amplifier channels inside a compact MCP6022 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

Complementary CMOS input paths cover the common-mode range near both supply rails. Their offset and bias behavior still varies with common-mode voltage and temperature; rail-to-rail does not remove input protection limits.

Gain and compensation

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

Output drivers

Each channel drives a compatible load close to its rails. The remaining headroom depends on load and current direction. The short-circuit current is a fault characteristic, not a normal drive-current promise.
