Key Features
- Rail-to-rail output swing enabling full dynamic range in single-supply systems down to 2.5 V
- Ultra-low input bias current of 80 pA maximum, ideal for high-impedance sensor interfaces and charge amplifiers
- Guaranteed 75 dB minimum CMRR (91 dB typical) for accurate differential signal processing in noisy environments
Applications
The MCP606-I/P is suitable for battery-powered sensor signal conditioning where low supply current and rail-to-rail output swing maximize dynamic range. It is commonly used in pH meter front ends, weigh scale amplifiers, and general-purpose active filter stages operating from single-supply voltages as low as 2.5 V. The through-hole PDIP-8 package also makes it convenient for prototyping and breadboard development of analog circuits.

Frequently Asked Questions
How does the MCP606-I/P achieve rail-to-rail output in single-supply designs running at 3.3 V?
The MCP606-I/P uses an output stage designed to swing within a few millivolts of both supply rails, allowing its output to reach nearly 0 V and nearly 3.3 V in a single-supply 3.3 V system. This maximizes the usable dynamic range for ADC driving and signal conditioning without requiring dual supplies, with a 155 kHz gain-bandwidth product maintained across the output swing range.
For a high-impedance pH or electrochemical sensor interface, why is the 80 pA bias current of the MCP606-I/P significant?
Electrochemical sensors typically have source impedances above 10 MΩ. With a maximum input bias current of 80 pA, the voltage error introduced at a 10 MΩ source impedance is only 0.8 mV, which is negligible for most measurement applications. This makes the MCP606-I/P a practical choice without requiring expensive FET-input op-amps for moderate-precision pH measurements.
How does the MCP606-I/P PDIP-8 package compare to SOIC-8 variants for prototyping versus production use?
The PDIP-8 package uses 2.54 mm pin pitch and fits standard DIP sockets, making it ideal for breadboard and stripboard prototyping. In contrast, SOIC-8 variants share the same die but use a 1.27 mm pitch SMD footprint that is smaller at approximately 4.9 mm x 3.9 mm, preferred in production PCBs where board space is limited.
What active filter topologies can the MCP606-I/P support given its 155 kHz gain-bandwidth product?
The 155 kHz gain-bandwidth product allows the MCP606-I/P to implement low-pass and band-pass active filters with cutoff frequencies up to approximately 10 kHz at a closed-loop gain of 10, or up to 50 kHz at unity gain. It is well matched to audio-frequency and sensor signal conditioning Sallen-Key and multiple-feedback filter stages with supply voltages from 2.5 V to 5.5 V.
