- 80 dB minimum / 100 dB typical CMRR rejects supply and common-mode noise in differential signal paths
- Dual op-amp in compact 8-pin MSOP package saves board space and simplifies two-channel active filter and amplifier designs
- Pb-free, RoHS-compliant construction with voltage-feedback architecture suits cost-sensitive consumer and industrial low-power applications
Applications
MCP617-I/MS is suited for portable battery-powered instruments, medical monitoring devices, and IoT sensor nodes where two precision amplifier channels are needed in a minimum footprint. Its 5 nA input bias current makes it a reliable front end for resistive bridge sensors, photodiodes, and electrochemical cells where source impedances exceed 1 MΩ. Active filter stages, precision voltage followers, and instrumentation amplifier gain stages in data acquisition systems also benefit from the dual configuration and high CMRR.

Frequently Asked Questions
How does the MCP617-I/MS input bias current of 5 nA affect accuracy when interfacing a 10 MΩ pH electrode?
With a 10 MΩ source impedance and 5 nA maximum input bias current, the MCP617-I/MS introduces up to 50 mV of bias-current-induced offset voltage at the input. For pH measurements where 1 pH unit corresponds to approximately 59 mV, this represents nearly 1 pH unit of error. Keeping source impedance below 1 MΩ or using a guarding technique limits this offset to 5 mV or less, preserving pH measurement accuracy to better than 0.1 pH.
What is the CMRR of the MCP617-I/MS, and how does it benefit a Wheatstone bridge measurement circuit?
The MCP617-I/MS achieves a minimum CMRR of 80 dB and a typical value of 100 dB. In a Wheatstone bridge excited at 5 V, a common-mode voltage of 2.5 V is rejected to well below 25 µV at the output with 100 dB CMRR, allowing millivolt-level differential bridge signals from strain gauges or RTDs to be amplified cleanly without interference from supply or substrate noise.
Which package does the MCP617-I/MS use, and how does it compare to a standard SOIC-8 footprint in area?
The MCP617-I/MS ships in an 8-pin MSOP (Mini Small Outline Package) with a body size of approximately 3x3 mm and 0.65 mm pin pitch, roughly 60% smaller in area than a standard SOIC-8 package at 5x4 mm. This size advantage is significant in portable designs where two op-amp channels must fit alongside passive components on a small PCB, such as a wearable sensor patch or handheld meter.
For a 2-channel active low-pass filter at 1 kHz, can a single MCP617-I/MS replace two discrete op-amps?
Yes. The MCP617-I/MS integrates 2 independent op-amps in a single MSOP-8 package, directly replacing two single op-amp devices. Each channel is a full voltage-feedback amplifier capable of forming a Sallen-Key or multiple-feedback low-pass filter with external resistors and capacitors. Using a single MCP617-I/MS reduces BOM by at least 1 device and eliminates one PCB footprint, simplifying layout for dual-channel anti-aliasing or signal conditioning filters operating below the amplifier's gain-bandwidth product.
