What are the key features of MCP608-I/SN?
- Ultra-low 25 µA quiescent current with 2.5 V minimum supply enables long battery life in portable and energy-harvesting designs
- 91 dB typical CMRR and 0.00008 µA maximum bias current ensure high accuracy in precision signal conditioning circuits
- Integrated chip select (CS) feature allows power gating the op-amp in multi-stage analog signal chains
What is MCP608-I/SN used for?
The MCP608-I/SN is designed for battery-powered sensor front-ends, portable medical devices, and IoT node analog stages where minimizing quiescent current is critical. Its 2.5 V minimum supply and 25 µA operating current make it compatible with single-cell lithium and alkaline battery systems. The high 91 dB CMRR suits differential sensor amplification in noisy industrial and consumer environments.

Frequently Asked Questions
What is the quiescent current of the MCP608-I/SN, and how does it compare to standard op-amps in battery applications?
The MCP608-I/SN draws only 25 µA of quiescent current at a 2.5 V supply, which is significantly lower than standard general-purpose op-amps that typically consume 0.5 mA to 5 mA. This makes it ideal for battery-powered sensors, wearable devices, and IoT nodes where extending battery life from months to years is a design priority.
Which precision sensor amplification designs benefit from the MCP608-I/SN's 91 dB CMRR and 0.00008 µA bias current?
Bridge sensor amplifiers, thermocouple interfaces, and electrochemical sensor front-ends benefit most from the 91 dB typical CMRR and 0.00008 µA maximum bias current. These specifications reject power supply and common-mode noise while minimizing offset errors from source impedance interaction, enabling sub-millivolt measurement accuracy in temperature, pressure, and chemical sensing circuits.
How does the chip select (CS) feature of MCP608-I/SN benefit multi-stage analog signal chain designs?
The CS input allows the MCP608-I/SN to be powered down when not actively sampling, reducing average system current below 25 µA in duty-cycled sensor designs. In multi-stage pipelines with 2 or more op-amp stages, selectively disabling inactive stages via CS saves meaningful energy over thousands of sample cycles in SOIC-8 compact board designs.
