What are the key features of MCP602-I/SN?
- Ultra-low 60 fA maximum input bias current minimizes leakage error in high-impedance sensor and transimpedance amplifier front-ends
- 90 dB typical common-mode rejection ratio enables accurate differential signal recovery in noisy single-supply data acquisition systems
- Rail-to-rail output swing in RoHS-compliant SOIC-8 maximizes dynamic range in 3.3 V and 5 V single-supply precision measurement circuits
What is MCP602-I/SN used for?
The MCP602-I/SN targets single-supply precision signal conditioning in battery-powered sensor nodes, photodetector transimpedance amplifiers, and medical biosensor front-ends where 60 fA bias current is essential for accurate measurement of high-source-impedance signals. Its 90 dB CMRR and rail-to-rail output make it effective in instrumentation amplifier stages for thermocouple and bridge sensor conditioning operating from 2.7 V to 6 V single-rail supplies. Industrial data acquisition modules and portable analytical instruments use its dual-channel integration in SOIC-8 to reduce BOM component count while maintaining sub-millivolt precision.

Frequently Asked Questions
How does the MCP602-I/SN's 60 fA bias current compare to standard BJT op-amps in a pH electrode measurement circuit?
The MCP602-I/SN's maximum input bias current of 60 fA (0.00006 µA) is over 1000x lower than typical BJT op-amps at 100 nA, which translates to less than 60 µV of offset error across a 1 GΩ glass pH electrode source impedance. This makes the MCP602 suitable for direct pH meter front-end amplification without a buffer stage, while BJT-input op-amps would introduce over 100 mV systematic error in the same circuit.
What supply voltage range does the MCP602-I/SN support, and how does it fit into a 3.3 V microcontroller-based design?
The MCP602-I/SN operates from a single supply of 2.7 V to 6 V, making it directly compatible with 3.3 V and 5 V microcontroller power rails without a separate analog supply. Its rail-to-rail output stage swings within a few millivolts of both supply rails, allowing the full ADC input range of a 12-bit, 3.3 V microcontroller to be utilized without signal headroom loss.
What CMRR does the MCP602-I/SN achieve, and how does this benefit a Wheatstone bridge strain gauge amplifier?
With 75 dB minimum and 90 dB typical CMRR, the MCP602-I/SN rejects common-mode noise on a Wheatstone bridge output to below 30 µV referred to input, suppressing 50 Hz mains interference induced on both bridge legs equally. For a 350 Ω full-bridge strain gauge with 2 mV/V sensitivity at 5 V excitation, this CMRR level maintains measurement accuracy better than 0.1% full scale without additional shielding.
Is the MCP602-I/SN recommended for new PCB designs, and what is its package lead finish?
The MCP602-I/SN carries a Pb-free code of Yes and a YTEOL of 8, indicating it is in active production with approximately 8 or more years of estimated remaining supply life, making it suitable for new designs. It uses a RoHS-compliant lead-free finish in the SOIC-8 package (JESD-30 R-PDSO-G8) with 1.27 mm lead pitch, compatible with standard 260°C peak reflow assembly processes.
