What are the key features of MCP6142-I/SN?
- Dual op-amp operating from 1.6 V single supply, ideal for single-cell battery and energy-harvesting applications
- Ultra-low 0.005 µA maximum input bias current for accurate high-impedance sensor signal conditioning
- 62 dB minimum CMRR and 100 kHz gain-bandwidth product in a compact SOIC-8 package
What is MCP6142-I/SN used for?
The MCP6142-I/SN is suited for battery-powered portable instruments, wearable biosensors, and low-voltage data acquisition front-ends where signal conditioning must operate reliably from a 1.6 V single-cell supply. Its nanoamp input bias current makes it ideal for interfacing with high-impedance pH electrodes, strain gauges, and photodiode transimpedance amplifier stages. The dual-channel configuration in a single SOIC-8 package reduces BOM cost and board area in compact analog signal chains.

Frequently Asked Questions
What is the minimum supply voltage and gain-bandwidth product of the MCP6142-I/SN?
The MCP6142-I/SN operates from a minimum supply voltage of 1.6 V and has a gain-bandwidth product of 100 kHz. This combination allows it to amplify low-frequency sensor signals up to audio-band frequencies in single-cell battery designs, such as those powered by a 1.5 V alkaline or 1.8 V lithium coin cell.
How does the 0.005 µA input bias current of MCP6142-I/SN benefit high-impedance sensor interfaces?
With a maximum input bias current of only 0.005 µA (5 nA), the MCP6142-I/SN introduces negligible loading error on high-impedance sources such as pH electrodes, piezoelectric sensors, and photodiodes. This low bias current prevents significant voltage offset at the amplifier input, preserving measurement accuracy in precision sensor signal conditioning circuits operating from 1.6 V.
For a wearable ECG front-end operating at 1.8 V, what does the MCP6142-I/SN's CMRR specification offer?
The MCP6142-I/SN provides a minimum 62 dB CMRR (typical 80 dB), which effectively rejects common-mode power-line interference and motion artifacts on both ECG electrode inputs. At a 1.8 V supply, this rejection level helps maintain signal fidelity in wearable biopotential amplifiers where differential biopotential signals are only a few millivolts against large common-mode noise.
When would a designer choose MCP6142-I/SN over a rail-to-rail op-amp with higher bandwidth?
MCP6142-I/SN is the right choice when the priority is operation below 1.8 V with nanoamp bias currents rather than maximum bandwidth. In applications like low-power glucose monitors, environmental gas sensors, or thermocouple amplifiers where signals are below 10 kHz and supply is a 1.6 V to 3.6 V battery, the MCP6142-I/SN's 100 kHz GBP is sufficient and its ultra-low bias current outweighs the advantages of wider-bandwidth alternatives.
