What are the key features of MCP6021-I/ST?
- 10 MHz gain-bandwidth product with rail-to-rail input and output for maximum dynamic range in 2.5 V to 5.5 V single-supply designs
- Ultra-low 0.15 nA maximum input bias current suitable for high-impedance sensor interfaces and photodiode transimpedance amplifier circuits
- 74 dB minimum common-mode rejection ratio (CMRR) with 90 dB typical, enabling precise differential signal amplification in noisy environments
What is MCP6021-I/ST used for?
The MCP6021-I/ST is used in active filter stages, sensor signal conditioning, and data acquisition front-ends where 10 MHz bandwidth and low input bias current are required at supply voltages down to 2.5 V. Its rail-to-rail output swing maximizes ADC input utilization in 5 V and 3.3 V systems, while the low quiescent current suits battery-powered instruments and wearable sensor nodes. Photodiode transimpedance amplifiers and precision integrators benefit from the 0.15 nA input bias current specification.

Frequently Asked Questions
What gain-bandwidth product does the MCP6021-I/ST offer, and how does this limit usable closed-loop bandwidth in a gain-of-10 configuration?
The MCP6021-I/ST has a 10 MHz gain-bandwidth product. At a closed-loop gain of 10 V/V (20 dB), the usable bandwidth is 10 MHz divided by 10, giving approximately 1 MHz -3 dB bandwidth. This makes it suitable for audio amplifiers, active filters up to 500 kHz, and sensor conditioning circuits where signals are below 1 MHz.
How does the MCP6021-I/ST input bias current specification affect photodiode transimpedance amplifier accuracy?
With a maximum input bias current of 0.15 nA, the MCP6021-I/ST introduces a DC output offset equal to 0.15 nA multiplied by the feedback resistor value when used as a transimpedance amplifier. For a 1 MΩ feedback resistor, this yields a worst-case DC offset of only 150 µV at the output, making it accurate enough for low-light photodiode applications without offset trim. Larger feedback resistors up to 10 MΩ keep offset below 1.5 mV.
How does the MCP6021-I/ST rail-to-rail output swing compare to standard op-amps in a 3.3 V single-supply data acquisition system?
Standard op-amps with non-rail-to-rail outputs typically limit output swing to within 1 V to 1.5 V of each rail, leaving only 0.3 V to 1.3 V usable on a 3.3 V supply. The MCP6021-I/ST output swings to within 25 mV of both supply rails, providing approximately 3.25 V of output range. This directly maximizes the input span of a 12-bit ADC connected to the op-amp output, recovering up to 37% more dynamic range compared to a non-rail-to-rail alternative.
