Key Features
- Dual op-amp channels operating from a minimum supply of 1.6 V for single-cell and energy-harvesting designs
- Ultra-low input bias current of 0.1 nA (max) minimizes errors in high-impedance sensor signal paths
- 14 kHz gain-bandwidth product with internal frequency compensation for stable low-power filter and amplifier stages
- CMRR of 62 dB minimum / 80 dB typical ensures reliable common-mode noise rejection in differential sensor inputs
- 8-pin MSOP package (MSOP-8) balances small footprint with dual-channel functionality for portable PCB designs
Applications
The MCP6042-I/MS is commonly used in battery-powered sensor interfaces, photodiode transimpedance amplifiers, and ultra-low-power active filters where minimizing supply current is the primary design constraint. It also finds application in medical wearables, agricultural monitoring nodes, and portable instrumentation that require dual op-amp channels from a single 1.6 V to 5.5 V supply rail.

Frequently Asked Questions
How does the 0.1 nA input bias current of MCP6042-I/MS affect high-impedance sensor interface designs?
With a maximum input bias current of 0.1 nA, MCP6042-I/MS introduces negligible error voltage when interfacing with high-impedance sources such as pH electrodes, photodiodes, or piezoelectric sensors with source impedances in the megaohm range, allowing accurate signal acquisition without large offset compensation networks.
Can MCP6042-I/MS operate directly from a single 1.6 V lithium coin cell for always-on monitoring?
Yes. MCP6042-I/MS is specified to operate from a supply voltage as low as 1.6 V, making it compatible with discharged CR2032 coin cells and fully discharged AAA batteries. Its micropower quiescent current ensures years of continuous operation in duty-cycled sensor nodes that budget only a few microamps of average current.
What CMRR performance does MCP6042-I/MS guarantee, and why does it matter for bridge sensor circuits?
MCP6042-I/MS guarantees a minimum CMRR of 62 dB and a typical CMRR of 80 dB at the 14 kHz gain-bandwidth limit. In Wheatstone bridge or differential thermocouple amplifier circuits, higher CMRR reduces common-mode interference from power supply ripple and electromagnetic noise, improving measurement accuracy in millivolt-level output bridge sensors.
