What are the key features of MCP606-I/ST?
- Ultra-low 25 µA maximum supply current for extended battery life
- 2.5 V minimum supply voltage for single-cell and dual-cell battery operation
- 91 dB typical common-mode rejection ratio for accurate differential measurements
- Internal frequency compensation for unconditional stability
- Compact 8-pin TSSOP package for space-constrained portable designs
What is MCP606-I/ST used for?
The MCP606-I/ST is optimized for battery-powered applications such as handheld meters, portable medical devices, and wireless sensor nodes where minimizing quiescent current is critical to extending battery life. Its 25 µA supply current and 2.5 V minimum operating voltage allow operation from a single lithium coin cell or two AA batteries without a boost converter. The high common-mode rejection ratio of 91 dB makes it effective for amplifying small differential signals from bridge sensors, thermocouples, and photodetectors in the presence of common-mode noise.

Frequently Asked Questions
How does the MCP606-I/ST achieve such low power consumption, and what battery configurations is it compatible with?
The MCP606-I/ST consumes only 25 µA of supply current, achieved through a CMOS voltage-feedback amplifier architecture with internal compensation that minimizes bias currents. The 2.5 V minimum supply voltage allows operation from two AA alkaline batteries (approximately 3 V nominal), a single lithium-ion cell at end-of-discharge, or a CR2032 coin cell. This makes it practical for sensor nodes and meters that must operate for months or years without battery replacement.
What common-mode rejection ratio does the MCP606-I/ST provide, and how does it benefit bridge sensor measurements?
The MCP606-I/ST achieves a typical common-mode rejection ratio of 91 dB, with a guaranteed minimum of 75 dB. This high CMRR suppresses common-mode noise that appears equally on both amplifier inputs, such as 50 Hz or 60 Hz power-line interference coupled into Wheatstone bridge sensor cables. In strain gauge or pressure sensor amplifier circuits, the 91 dB CMRR ensures that only the differential bridge imbalance signal is amplified, improving measurement accuracy significantly.
For an 8-pin TSSOP footprint constraint, how does MCP606-I/ST compare to larger op-amp packages in a portable design?
The MCP606-I/ST in 8-pin TSSOP occupies approximately 3 mm x 4.4 mm of board area, roughly 40% smaller than an equivalent 8-pin SOIC package which measures about 4 mm x 5 mm. This smaller footprint frees up valuable PCB space in compact portable instruments while maintaining the same 25 µA low-power performance. The TSSOP package also supports fine-pitch automated assembly at high production volumes, reducing manufacturing cost per unit.
