What are the key features of MCP6042-E/MS?
- Dual rail-to-rail input and output amplifier enabling signal processing across the full supply range from 1.8 V to 6 V
- Ultra-low input bias current of 5 nA maximum allowing accurate interfacing with high-impedance sensors and resistive bridges
- 80 dB typical CMRR (62 dB minimum) rejecting common-mode noise in differential sensor signal chains
- 8-pin MSOP package with 0.65 mm pitch minimizing PCB footprint in portable and space-constrained analog designs
- Single-supply operation from 1.8 V to 6 V supporting both 3.3 V and 5 V mixed-signal system power architectures
What is MCP6042-E/MS used for?
The MCP6042-E/MS is suited for portable, battery-powered instruments where its 1.8 V to 6 V single-supply operation and rail-to-rail output maximize dynamic range in low-voltage designs such as handheld multimeters and wearable health monitors. It is also used in precision sensor signal conditioning for pressure transducers, thermocouples, and photodiodes, where the 5 nA maximum input bias current and 80 dB CMRR minimize offset errors. Active filter and comparator stages in audio accessories and IoT sensor nodes benefit from its dual-channel MSOP-8 package.

Frequently Asked Questions
What supply voltage range does the MCP6042-E/MS support and how does rail-to-rail output benefit low-voltage systems?
The MCP6042-E/MS operates from 1.8 V to 6 V supply, and its rail-to-rail output swings within a few millivolts of both supply rails, maximizing usable output voltage swing in 3.3 V and 5 V single-supply systems for precision analog signal chains.
How low is the input bias current of the MCP6042-E/MS and which sensor types benefit most from this specification?
The MCP6042-E/MS has a maximum input bias current of 5 nA (0.005 µA), making it ideal for interfacing with high-impedance electrochemical sensors, pH electrodes, photodiodes in transimpedance configurations, and resistive bridge sensors where any larger bias current would introduce significant offset voltage errors.
What CMRR does the MCP6042-E/MS achieve and why does that matter for differential sensor measurements?
The MCP6042-E/MS provides a typical CMRR of 80 dB and a minimum of 62 dB, rejecting common-mode noise and 50 Hz or 60 Hz power-line interference by at least 4 orders of magnitude, which is critical for accurate differential measurements from Wheatstone bridges and instrumentation amplifier front ends.
How many amplifier channels are in the MCP6042-E/MS and what package does it use for space-constrained designs?
The MCP6042-E/MS contains 2 independent op-amp channels in an 8-pin MSOP package with a 0.65 mm pin pitch and a body of approximately 3 mm × 3 mm, enabling dual-channel signal conditioning in a footprint smaller than a standard SOIC-8.
