Applications
The MCP606-I/SN is optimized for always-on sensor nodes and IoT edge devices where total system current budget may be under 100 µA and supply voltage may drop to 2.5 V at end-of-battery life. Its 80 pA maximum bias current makes it a natural fit for buffering resistive bridge, thermistor, and pH electrode outputs without loading the sensor element. Active low-pass filter stages in heart-rate monitors, environmental loggers, and 4–20 mA loop transmitters also benefit from its combination of low power and high CMRR.

Frequently Asked Questions
How does the 25 µA supply current of the MCP606-I/SN extend battery life in a coin-cell IoT sensor node?
Drawing only 25 µA from a 3 V CR2032 coin cell (capacity approximately 220 mAh), the MCP606-I/SN op-amp alone would run for over 8,800 hours — more than a year of continuous operation — before the battery is depleted. In practice, duty-cycled sensor nodes that are active 1% of the time effectively reduce the quiescent contribution to sub-µA equivalent average current, making the MCP606-I/SN an excellent front-end choice for 5-year-lifetime wireless sensor designs.
Can the MCP606-I/SN accurately buffer a 10 kΩ resistive bridge output at 3 V supply for a 12-bit ADC?
Yes. With a maximum input bias current of 80 pA across a 10 kΩ source impedance, the MCP606-I/SN introduces only 0.8 µV of bias-current-induced offset — negligible relative to the LSB size of 730 µV for a 12-bit ADC on a 3 V reference. The 91 dB typical CMRR also suppresses supply-rail ripple below 3 µV referred to input, ensuring the ADC conversion error remains dominated by quantization noise rather than amplifier errors.
How does the MCP606-I/SN SOIC-8 package compare with SOT-23-5 alternatives when routing a low-pass filter with external resistors?
The SOIC-8 package provides 8 pins with 1.27 mm lead pitch, giving 3 spare pins for connecting passive filter components (R and C) without requiring vias or jumper wires that would be necessary with a 5-pin SOT-23-5. This simplifies PCB layout for a 2nd-order Sallen-Key filter using resistors of 10 kΩ and capacitors of 10 nF, reducing the risk of layout-induced noise pickup. The SOIC footprint also makes hand soldering and visual inspection easier during prototyping compared to 0.95 mm-pitch SOT-23-5 alternatives.
