Inside MCP6002

Two CMOS input paths, compensated gain and low-power output stages.

Two CMOS-input amplifier channels inside a compact MCP6002 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 CMOS inputs have very low typical bias current at room temperature. Leakage increases with temperature, and board contamination or high source impedance can dominate the error.

Gain and compensation

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

Output drivers

Each amplifier has a rail-to-rail output stage. Output swing is not exactly equal to the rails, especially as output current rises.
