What the MCP6021 does
The MCP6021/1R/2/3/4 family are rail-to-rail input and output operational amplifiers with 10 MHz bandwidth. These devices operate on a 2.5V to 5.5V supply and feature low noise of 8.7nV/√Hz at 10kHz. The single and dual variants offer low input offset voltage of ±500µV for industrial grades, while the quad version includes a Chip Select pin for power savings. The family supports Industrial and Extended temperature ranges from -40°C to +125°C. Engineers typically use these amplifiers in automotive applications, multi-pole active filters, audio processing, test equipment, and medical instrumentation. Available in various packages including SOT-23-5, PDIP, SOIC, TSSOP, and MSOP, the parts provide unity gain stability and low total harmonic distortion of 0.00053%.
