Applications
The MCP601-I/SN is a versatile single op amp optimized for low-power sensor signal conditioning in portable and battery-operated instruments where input leakage current must remain in the sub-nanoamp range. Its 75 dB CMRR makes it effective in rejecting supply ripple and electromagnetic interference in active low-pass filter stages ahead of ADCs. Medical monitoring equipment, environmental sensing modules, and consumer handheld meters also rely on this device for stable, low-noise amplification across the industrial temperature range.

Frequently Asked Questions
How does the 0.00006 µA input bias current of the MCP601-I/SN enable picoamp-level sensor interface designs?
At a maximum input bias current of 0.00006 µA, the MCP601-I/SN draws only 60 pA from the signal source under worst-case conditions. For a 10 MΩ source resistance such as a glass pH electrode or electrochemical sensor, this translates to a maximum bias-induced offset error of just 0.6 mV, allowing highly accurate readings without requiring a dedicated buffer stage.
What CMRR does the MCP601-I/SN achieve, and how does this protect a differential sensor reading from power supply noise?
The MCP601-I/SN achieves 75 dB minimum and 90 dB typical common-mode rejection ratio. At 90 dB typical CMRR, a 100 mV power supply ripple appears as only 3.2 µV of differential error at the output, ensuring that 12-bit or 16-bit ADC readings from bridge sensors or thermocouples are not corrupted by switching regulator noise present on the supply rail.
For a single-supply low-power data logger, how does the MCP601-I/SN in SOIC-8 compare to a dual-supply alternative for BOM simplicity?
Deploying the MCP601-I/SN on a single 2.7 V to 5.5 V supply eliminates the negative rail generator that dual-supply op amps require, removing at least one DC-DC converter and its associated passives from the BOM. The standard SOIC-8 footprint is also universally supported by PCB assembly houses, reducing sourcing risk compared to proprietary single-supply packages that may have limited second-source availability.
