Key Features
- Rail-to-rail input and output swing on a 6 V maximum supply enabling full signal range utilization without headroom loss in single-supply sensor interfaces
- 75 dB typical common-mode rejection ratio minimizing noise pickup in differential sensor amplifier and bridge measurement circuits
- Voltage-feedback architecture with internal frequency compensation in a 5-pin SOT-23 package simplifying stable gain-of-1 and higher closed-loop designs
Applications
The MCP6231RT-E/OT is used in battery-powered sensor signal conditioning, such as amplifying outputs from temperature sensors, pressure transducers, and photodiodes operating from a single 3.3 V or 5 V supply. Its rail-to-rail input and output capability maximizes dynamic range in low-voltage portable instruments and IoT sensor nodes where signal headroom is limited. The compact SOT-23-5 footprint and 6-week lead time support rapid prototyping and volume production of analog front-end circuits.

Frequently Asked Questions
What supply voltage range does the MCP6231RT-E/OT support, and does it work from a single-cell Li-ion battery?
The MCP6231RT-E/OT operates from a maximum supply of 6 V and is compatible with single-supply rails as low as 1.8 V in many configurations. A single-cell Li-ion battery delivers 3.0 V to 4.2 V, which falls well within this range, making the MCP6231RT-E/OT suitable for portable instruments, wearables, and IoT nodes powered directly from a single cell without a boost converter.
How does the 61 dB minimum CMRR of the MCP6231RT-E/OT affect performance in a differential sensor amplifier circuit?
A minimum common-mode rejection ratio of 61 dB means that a 1 V common-mode interference signal at the inputs appears as no more than 0.89 mV at the output, referenced to unity gain. In bridge sensor amplifiers operating in electrically noisy industrial environments, this level of CMRR helps suppress 50 Hz or 60 Hz power-line interference, reducing the need for additional filtering while maintaining measurement accuracy.
For a compact 3.3 V ADC input buffer, why is the rail-to-rail output of the MCP6231RT-E/OT important?
Rail-to-rail output on the MCP6231RT-E/OT ensures the op-amp can drive its output to within a few millivolts of both the 0 V and 3.3 V supply rails, utilizing the full ADC input range. Without rail-to-rail output, a conventional op-amp would clip the signal 0.5 V to 1 V from each supply, wasting 30% or more of a 16-bit ADC's dynamic range and reducing effective resolution in precision measurement applications.
