What are the key features of MCP6031-E/SN?
- 93 dB typical CMRR with 72 dB minimum specification ensures excellent common-mode noise rejection in precision amplifier circuits
- 0.0001 µA input bias current at 25°C minimises offset errors in high-impedance sensor interfaces and charge amplifiers
- Single-channel voltage-feedback op-amp in compact SOIC-8 simplifies board layout for precision analog signal chains
What is MCP6031-E/SN used for?
The MCP6031-E/SN is designed for precision low-power signal conditioning in temperature sensors, pressure transducers, and strain gauge bridges where input bias current below 0.1 nA is critical to accuracy. Its 93 dB typical CMRR suppresses power-line interference in industrial sensor front-ends and medical measurement equipment. The SOIC-8 package provides straightforward PCB placement alongside ADC inputs in data acquisition modules and portable instrumentation.

Frequently Asked Questions
How low is the input bias current of the MCP6031-E/SN at room temperature, and why does it matter for sensor interfaces?
At 25°C the MCP6031-E/SN input bias current is just 0.0001 µA, and remains below 0.005 µA across the full temperature range. For a sensor with 10 MΩ source impedance, this produces less than 1 mV of offset error, enabling accurate measurements from glass electrodes, photodiodes, and resistive humidity sensors.
What CMRR does the MCP6031-E/SN achieve and how does it reduce interference in differential sensor measurements?
The MCP6031-E/SN delivers 93 dB typical and 72 dB minimum CMRR, rejecting common-mode voltages such as 50 Hz or 60 Hz mains pickup by a factor of over 4000:1 typical. This is critical in industrial thermocouple amplifiers and wheatstone bridge circuits where long cable runs pick up significant common-mode noise.
When is the single-channel MCP6031-E/SN preferable to a dual or quad op-amp for a precision measurement front-end?
The MCP6031-E/SN is preferred when only one high-precision channel is needed and crosstalk between channels must be completely eliminated. A dual-package shares silicon, which can introduce channel-to-channel crosstalk of several microvolts at low frequencies, whereas the single MCP6031 in SOIC-8 provides full channel isolation for the most demanding low-noise measurements.
