Frequently Asked Questions

What bandwidth does the MCP618-I/SN support, and is it sufficient for audio-frequency signal conditioning?

The MCP618-I/SN has a gain-bandwidth product of 190 kHz. This is adequate for audio-range conditioning up to about 10 kHz at moderate gains, though high-fidelity audio or ultrasonic sensing applications above 100 kHz may require an op-amp with a higher GBW product.

How does the rail-to-rail output capability of MCP618-I/SN benefit single-supply 3.3 V sensor designs?

With rail-to-rail input and output, the MCP618-I/SN can swing close to both the 0 V ground and the 3.3 V rail, maximizing the usable dynamic range on a single-supply system. This prevents signal clipping and improves ADC utilization in sensor nodes operating from 2.3 V to 5.5 V.

When should a designer choose MCP618-I/SN over a higher-speed op-amp for a low-power portable instrument?

MCP618-I/SN is the right choice when the signal bandwidth is within 190 kHz and minimizing supply current matters more than speed. Its 0.005 µA max bias current and 2.3 V to 5.5 V supply range extend battery life in portable instruments, whereas higher-speed op-amps typically draw significantly more quiescent current.
