What are the key features of MCP6271RT-E/OT?
- Rail-to-rail input and output swing on a single supply up to 5.5 V, maximizing dynamic range in low-voltage sensor and signal conditioning circuits
- Ultra-low maximum bias current of 5 nA enabling accurate high-impedance source measurement with minimal loading error
- 65 dB minimum common-mode rejection ratio (85 dB typical) ensuring strong noise rejection in single-supply instrumentation amplifier stages
What is MCP6271RT-E/OT used for?
The MCP6271RT-E/OT is used in battery-powered sensor interfaces, portable medical monitors, and IoT node analog front-ends where a single-supply rail-to-rail op-amp in a compact SOT-23-5 package is needed. Its low 5 nA bias current and high CMRR make it well suited for precision transducer amplification, active filter stages, and voltage follower circuits in space-constrained, power-sensitive designs.

Frequently Asked Questions
What is the maximum bias current and CMRR of the MCP6271RT-E/OT, and why do these matter for sensor interfaces?
The MCP6271RT-E/OT has a maximum average bias current of 5 nA and a minimum CMRR of 65 dB (85 dB nominal), which together ensure minimal loading of high-impedance sensors and strong rejection of common-mode interference, critical for accurate signal conditioning in pH probes, thermocouples, and strain gauge bridges.
How does the rail-to-rail input/output architecture of the MCP6271RT-E/OT benefit single-supply 3.3 V or 5 V designs?
The rail-to-rail input and output capability allows the MCP6271RT-E/OT to handle signals from 0 V to the 5.5 V supply rail without signal clipping, maximizing the usable output voltage swing and analog dynamic range in single-supply 3.3 V or 5 V embedded sensor systems where dual supply rails are not available.
Which compact PCB layouts benefit from the MCP6271RT-E/OT in its SOT-23-5 package versus larger op-amp housings?
Wearable medical devices, miniature IoT sensors, and compact industrial transmitters benefit most from the MCP6271RT-E/OT in its 5-pin SOT-23-5 package, as its tiny footprint allows multiple amplifier stages to fit in the same area that a single SOIC-8 op-amp would occupy, with equivalent electrical performance up to 5.5 V supply.
What lead time and product lifecycle horizon should buyers plan for when procuring the MCP6271RT-E/OT in volume?
The MCP6271RT-E/OT has an 8-week factory lead time and a 9-year estimated end-of-life horizon, meaning volume buyers should establish safety stock and submit long-range purchase orders to avoid supply gaps, particularly for medical or industrial products with multi-year production runs that depend on this specific 5-pin SOT-23 op-amp.
