What are the key features of MCP6141T-E/OT?
- Ultra-low 5 nA maximum input bias current preserves signal accuracy when interfacing to high-impedance sensors such as pH electrodes and photodiodes
- 80 dB typical common-mode rejection ratio with internal frequency compensation ensures stable, low-noise operation across the full supply voltage range
- SOT-23-5 package with RoHS-compliant construction enables compact, single-supply analog front-end designs in portable and industrial applications
What is MCP6141T-E/OT used for?
MCP6141T-E/OT excels in high-impedance sensor interfaces such as pH meters, ion-selective electrodes, and pyroelectric infrared detector circuits where sub-10 nA input bias current prevents measurement errors. It is also used in transimpedance amplifiers for photodiode current sensing in optical receivers and barcode scanners. Battery-powered instrumentation, medical monitoring patches, and precision signal conditioning modules rely on its low bias current and compact SOT-23-5 footprint.

Frequently Asked Questions
How low is the input bias current of MCP6141T-E/OT and why does it matter for pH sensor circuits?
MCP6141T-E/OT has a maximum input bias current of just 5 nA (0.005 µA), which is critical for pH electrode amplifiers because the glass membrane electrode presents impedances above 100 MΩ. Even a 1 nA leakage current across 100 MΩ introduces 100 mV of error voltage, so a sub-10 nA bias current op-amp like MCP6141T is essential for accurate readings.
How does the 80 dB CMRR of MCP6141T-E/OT compare to MCP6001T-E/OT for differential measurement accuracy?
MCP6141T-E/OT achieves 80 dB typical CMRR versus MCP6001T's 76 dB, providing approximately 2.5 times better common-mode noise rejection. For bridge sensor and thermocouple amplifier designs operating near 50 Hz or 60 Hz power lines, the extra 4 dB reduces interference pickup and improves measurement resolution beyond what MCP6001T can achieve.
Can MCP6141T-E/OT serve as a transimpedance amplifier for photodiode current sensing?
Yes, MCP6141T-E/OT is well-suited for transimpedance amplifier (TIA) designs because its 5 nA maximum bias current contributes less than 5 mV of offset across a 1 MΩ feedback resistor, keeping photodiode dark-current errors small. The internal frequency compensation prevents oscillation at high feedback resistance values common in optical sensing circuits.
What lead time and package options should procurement consider when ordering MCP6141T-E/OT in volume?
MCP6141T-E/OT carries a 6-week factory lead time and comes in the SOT-23-5 tape-and-reel package, compatible with high-volume automated SMT assembly lines. For designs needing an even smaller footprint, Microchip offers the same MCP6141 die in a 5-pin SC-70 package; planning 8–10 weeks of safety stock covers the standard 6-week replenishment cycle.
