What are the key features of MCP608-I/ST?
- Ultra-low 25 µA supply current enabling long battery life in portable sensing designs
- 91 dB typical CMRR with voltage-feedback architecture for precision signal conditioning
- 2.5 V minimum supply voltage in compact 8-pin TSSOP package for space-constrained layouts
What is MCP608-I/ST used for?
The MCP608-I/ST is designed for battery-powered instrumentation, portable medical monitors, and low-power sensor front ends where supply current must remain below 25 µA. Its 2.5 V minimum supply makes it compatible with single-cell lithium or alkaline battery systems. Engineers also use it in precision data acquisition stages and active filter circuits that require high CMRR with minimal quiescent power draw.

Frequently Asked Questions
How low is the quiescent current of the MCP608-I/ST, and why does it matter for battery-powered designs?
The MCP608-I/ST draws only 25 µA of supply current, which is critical for extending runtime in battery-powered equipment. At this current level, a 200 mAh coin cell can sustain the op-amp alone for over 8000 hours, making it suitable for always-on sensor nodes and wearable health monitors that must operate for months between charges.
What CMRR performance does the MCP608-I/ST provide for precision measurement circuits?
The MCP608-I/ST achieves a typical CMRR of 91 dB with a minimum guaranteed value of 75 dB. This level of common-mode rejection suppresses noise and ground offsets effectively in differential sensing applications such as bridge amplifiers, strain-gauge conditioners, and thermocouple interfaces where even small common-mode voltages can corrupt the output reading.
Can the MCP608-I/ST operate from a single 2.5 V rail in a compact TSSOP-8 footprint?
Yes. The MCP608-I/ST supports single-supply operation starting at 2.5 V, which is compatible with 3 V lithium coin cells and regulated outputs from low-dropout regulators. Its 8-pin TSSOP-8 package measures approximately 3 mm x 4.4 mm, occupying minimal PCB area in handheld or wearable products where board space is at a premium.
When is the MCP608-I/ST preferable to a standard general-purpose op-amp in an IoT sensing front end?
The MCP608-I/ST is preferable when the design budget for the amplifier stage is below 25 µA and the supply rail is as low as 2.5 V. Standard general-purpose op-amps often draw 0.5 mA to 2 mA, which can consume 20x to 80x more current. For IoT nodes that wake and sleep on a duty cycle with a 6-week lead time in production, the MCP608-I/ST reduces both board current budget and BOM complexity.
