- Ultra-low 5 nA maximum input bias current minimizes measurement error in high-impedance sensor interface circuits
- 90 dB typical CMRR with 74 dB minimum ensures robust common-mode noise rejection in differential signal paths
Applications
The MCP6021-E/SN is designed for precision analog signal conditioning in data acquisition systems, ADC driver stages, and active filter designs where 10 MHz bandwidth, rail-to-rail output, and 5 nA bias current deliver high accuracy at low supply voltages. It suits photodiode transimpedance amplifiers, resistive bridge amplifiers, and thermocouple signal conditioning circuits benefiting from 90 dB CMRR noise rejection. The 8-pin SOIC-8 package and 2.5 V to 5.5 V supply range support both legacy 5 V industrial instrumentation and modern 3.3 V embedded sensor front ends.

Frequently Asked Questions
How does the MCP6021-E/SN's 10 MHz gain-bandwidth product compare to MCP616 for higher-speed ADC driver designs?
The MCP6021-E/SN offers a 10 MHz gain-bandwidth product, which is approximately 10× wider than the MCP616's bandwidth, enabling closed-loop gains of 10× up to 1 MHz for ADC driver and active filter applications. This makes the MCP6021 suitable for driving 12-bit to 16-bit SAR ADCs with input frequencies up to several hundred kHz, while MCP616 suits lower-frequency sub-100 kHz sensor conditioning.
For a photodiode transimpedance amplifier, why is the 5 nA bias current of MCP6021-E/SN important?
In a transimpedance amplifier with a 1 MΩ feedback resistor, the 5 nA maximum input bias current of MCP6021-E/SN contributes at most 5 mV of output offset, keeping measurement error below the LSB of a 12-bit ADC referenced to 5 V. Higher-bias amplifiers with 100 nA or more would add 100 mV or greater offset, degrading dynamic range in low-light photodetection applications.
What common-mode rejection ratio does MCP6021-E/SN guarantee, and how does it benefit industrial sensor designs?
The MCP6021-E/SN guarantees a minimum CMRR of 74 dB and achieves a typical 90 dB, rejecting common-mode interference such as 50 Hz or 60 Hz power-line coupling by a factor of at least 5,000× minimum. This ensures that Wheatstone bridge outputs and thermocouple differential signals remain accurate even when the sensor wiring runs near noisy AC power cables in industrial environments.
What supply voltage range and output swing does MCP6021-E/SN support for single-supply embedded systems?
The MCP6021-E/SN operates from a single supply of 2.5 V to 5.5 V with a rail-to-rail output stage that swings within a few millivolts of both supply rails, maximizing the usable dynamic range of the analog output. This rail-to-rail swing is critical when driving a 3.3 V ADC from a 3.3 V supply, as it avoids clipping the signal at the top and bottom of the conversion range.
