Key Features
- 10 MHz gain-bandwidth product with rail-to-rail input and output on 2.5 V to 6 V single supply, enabling high-frequency ADC driver and active filter designs
- Ultra-low 150 fA maximum input bias current and 90 dB CMRR support precision measurement of high-impedance sensors such as photodiodes and pH electrodes
- Single op-amp in SOIC-8 with voltage-feedback architecture and internal frequency compensation, requiring only bypass capacitors for stable single-supply operation
Applications
The MCP6021-I/SN is used as a precision ADC driver, active low-pass filter, and transimpedance amplifier in portable instrumentation, medical diagnostic equipment, and industrial sensor front ends operating from 3.3 V or 5 V single supplies. Its 10 MHz bandwidth supports signal conditioning for audio-range and ultrasonic sensors, while the 150 fA input bias current minimizes error when interfacing to photodiodes, ion-selective electrodes, or high-impedance temperature sensors. The SOIC-8 package suits both prototype breadboarding and volume production on standard SMT assembly lines.

Frequently Asked Questions
What gain-bandwidth product does MCP6021-I/SN offer, and at what gain is 1 MHz closed-loop bandwidth achieved?
MCP6021-I/SN has a 10 MHz gain-bandwidth product. A closed-loop bandwidth of 1 MHz is achieved at a non-inverting gain of 10 V/V (20 dB). At unity gain the amplifier is stable with bandwidth of the full 10 MHz, making it suitable as a buffer driving ADC sample-and-hold inputs at sampling rates up to several MSPS.
How does MCP6021-I/SN's 150 fA input bias current enable accurate photodiode transimpedance amplifier designs?
In a transimpedance amplifier with a 100 MΩ feedback resistor, the DC output error due to input bias current is 150 fA × 100 MΩ = 15 µV — negligible compared to the photocurrent signal. This extremely low bias current, combined with the 90 dB CMRR and rail-to-rail output, allows detection of photodiode currents as small as 1 pA on a 3.3 V single supply without saturating the output.
Can MCP6021-I/SN replace an MCP601 or MCP6001 in an existing 5 V single-supply design without PCB changes?
Yes. MCP6021-I/SN is pin-compatible with MCP601 and MCP6001 in SOIC-8, and shares the same 2.5 V to 6 V supply range. The MCP6021 increases bandwidth from 2.8 MHz (MCP6001) to 10 MHz, which benefits active filters and ADC drivers needing higher frequency headroom. No PCB layout changes are required, though the feedback network may need re-optimization for the higher gain-bandwidth product.
What supply voltage range does MCP6021-I/SN support, and how does single-supply 3.3 V operation compare to split-supply ±5 V for sensor conditioning?
MCP6021-I/SN operates from 2.5 V to 6 V single supply. In a 3.3 V single-supply configuration the rail-to-rail output swings within approximately 100 mV of both rails, recovering nearly 3.1 V of usable output range. This eliminates the need for a negative supply rail, reducing power converter complexity and quiescent current compared to a split ±5 V supply, while still providing 10 MHz bandwidth adequate for most sensor conditioning tasks up to 100 kHz signal frequencies.
