Frequently Asked Questions
What is the minimum supply voltage for the MCP617-I/SN and how does it suit battery-powered circuits?
The MCP617-I/SN operates from a minimum supply voltage of 2.3 V, making it compatible with a single lithium coin cell or two alkaline AA cells in series. This low supply threshold allows the amplifier to remain functional as the battery discharges, extending the usable life of portable instruments and wearable sensors.
How does the 100 dB typical CMRR of the MCP617-I/SN benefit differential signal measurement designs?
A 100 dB typical CMRR means the MCP617-I/SN rejects common-mode interference by a factor of 100,000, which is critical for measuring small differential signals from Wheatstone bridge sensors or thermocouple pairs in noisy industrial environments. The 80 dB minimum CMRR is maintained across the operating temperature range.
When would a designer choose the MCP617-I/SN over a standard CMOS op-amp for a 2-channel sensor front end?
A designer would prefer the MCP617-I/SN when source impedances exceed 10 MΩ, since its 5 nA maximum bias current keeps DC offset below 50 mV even at those impedances. For standard CMOS op-amps with bias currents in the microampere range, the resulting error at 10 MΩ source impedance would be 10 V, making the MCP617 the correct choice for high-impedance electrochemical or pH sensors.
