Key Features
- Operates from 1.6 V single supply with 14 kHz gain-bandwidth product, enabling ultra-low-power amplification in coin-cell and energy-harvesting battery sensor designs
- 100 fA maximum input bias current is among the lowest available in any op-amp, allowing direct connection to high-impedance sources such as pH electrodes and MEMS sensors without offset errors
- Chip-select shutdown pin reduces supply current to under 1 µA in standby mode, extending battery life in duty-cycled IoT sensor nodes and portable medical monitors
Applications
The MCP6043-I/MS is designed for ultra-low-power precision signal conditioning in portable medical devices, environmental sensors, and wearable electronics where the 1.6 V minimum supply aligns with single-cell lithium or alkaline battery voltages. Its 100 fA bias current makes it ideal for charge amplifiers connected to piezoelectric sensors, MEMS microphones, or capacitive humidity probes where source impedances exceed 100 MOhm. The chip-select feature allows the amplifier to be powered down between measurement cycles in duty-cycled glucose monitors, air quality sensors, and industrial wireless sensor nodes.

Frequently Asked Questions
What is the minimum supply voltage and gain-bandwidth product of the MCP6043-I/MS, and what does this mean for battery-powered designs?
The MCP6043-I/MS operates from a minimum of 1.6 V single supply with a 14 kHz gain-bandwidth product. At 1.6 V, it can amplify DC to audio-frequency signals from sensors powered by a single alkaline or lithium coin cell, making it suitable for wearable health monitors and wireless sensor nodes where supply voltage drops below 2 V near end-of-battery life.
How does the 100 fA maximum bias current of MCP6043-I/MS benefit high-impedance sensor interfaces compared to standard op-amps?
At only 100 fA maximum bias current, the MCP6043-I/MS introduces less than 0.1 mV offset error even with source impedances up to 1 GOhm. This is approximately 1000 times lower than general-purpose CMOS op-amps with 100 pA bias current, making it essential for pH electrode buffers, MEMS capacitive sensors, and piezoelectric charge amplifier circuits where bias-current-induced errors dominate accuracy.
What is the chip-select shutdown feature on MCP6043-I/MS and how much power does it save in duty-cycled IoT applications?
The chip-select pin disables the amplifier and reduces supply current to under 1 µA. In an IoT sensor node that takes 1 reading per second with a 10 ms active window, this cuts average current consumption by over 99% compared to leaving the op-amp always on, extending a 100 mAh coin-cell battery life from weeks to over a year in typical environmental monitoring applications.
What package does MCP6043-I/MS use and how does it compare to standard SOIC-8 for space-constrained wearable designs?
The MCP6043-I/MS is housed in an MSOP-8 package measuring approximately 3 mm x 3 mm with 0.65 mm pitch, which is roughly 50% smaller in footprint than a standard SOIC-8 package at 4.9 mm x 3.9 mm. This compact size is well-suited for wearable medical patches, hearing aid modules, and miniaturized environmental sensor boards where PCB area is limited to under 5 cm².
