Frequently Asked Questions
What supply voltage range does the MCP6231UT-E/OTVAO support, and can it work in 1.8 V microcontroller systems?
The MCP6231UT-E/OTVAO operates from a supply voltage as low as 1.8 V up to 5.5 V, making it directly compatible with 1.8 V and 3.3 V microcontroller systems without additional level shifting or power conversion stages.
How does the 300 kHz gain-bandwidth product of the MCP6231UT-E/OTVAO limit its use in audio or higher-frequency filter designs?
With a gain-bandwidth product of 300 kHz, the MCP6231UT-E/OTVAO is best suited for DC and low-frequency signal conditioning up to a few tens of kilohertz at unity gain. At higher closed-loop gains, the usable bandwidth decreases proportionally, so audio applications above 20 kHz at gains above 10 may require a higher-bandwidth alternative op-amp.
Which automotive sensor applications are best matched to the MCP6231UT-E/OTVAO given its 75 dB CMRR and E temperature grade?
The 75 dB typical CMRR and extended E temperature rating covering -40°C to +125°C make the MCP6231UT-E/OTVAO well suited for amplifying differential signals from pressure sensors, temperature sensors, and Hall-effect transducers in automotive body control modules and HVAC systems.
