Key Features
- Ultra-low 60 nA quiescent current with rail-to-rail input and output swing, enabling years of operation from small coin-cell batteries at 1.4 V to 6 V
- 0.0001 µA (0.1 pA) maximum input bias current minimizes errors in high-impedance sensor interfaces such as pH electrodes and photodiodes
- 80 dB typical CMRR with internal frequency compensation in a standard SOIC-8 package for easy drop-in signal-conditioning designs
Applications
The MCP6041-I/SN is ideal for energy-harvesting nodes, medical-grade biosensors, and long-life wireless sensor transmitters where average supply current must remain below 1 µA. Its near-zero 0.1 pA bias current suits high-impedance electrochemical and optical sensors that cannot tolerate input loading. The 1.4 V minimum supply allows direct operation from a single thin-film or alkaline cell in IoT edge devices.

Frequently Asked Questions
How does the 60 nA quiescent current of the MCP6041-I/SN extend battery life in always-on sensor nodes?
At 60 nA quiescent current, a 200 mAh coin cell would theoretically power the MCP6041-I/SN alone for over 3,000 hours continuously. In duty-cycled IoT sensor nodes that sleep most of the time, this nano-power draw makes the op-amp effectively transparent in the overall power budget, extending field replacement intervals to several years.
What input bias current spec makes the MCP6041-I/SN suitable for pH and electrochemical sensors?
The MCP6041-I/SN specifies a maximum input bias current of 0.0001 µA (100 fA effective), which is essential for pH electrodes and ion-selective sensors with source impedances in the gigaohm range. Drawing even a few picoamps from such sensors would create millivolt-level errors that render the measurement useless.
Can the MCP6041-I/SN operate from a 1.5 V alkaline cell and still maintain rail-to-rail output swing?
Yes, the MCP6041-I/SN is specified to operate from a minimum supply of 1.4 V, so a fresh 1.5 V alkaline cell provides adequate headroom. The rail-to-rail output swings to within a few millivolts of both supply rails at light loads, maximising the usable output range when the supply sags to 1.1 V near end of battery life.
How does the MCP6041-I/SN compare to the MCP6001 for a low-power photodiode transimpedance amplifier?
The MCP6041-I/SN draws roughly 60 nA versus the MCP6001's typical 100 µA, making it approximately 1,700 times lower in quiescent current. For a photodiode TIA application requiring gain above 10 MΩ, the MCP6041's 0.1 pA bias current also produces far less dark-current offset than the MCP6001, improving signal fidelity at low light levels.
