- Rail-to-rail input and output swing maximizes dynamic range on low supply voltages from 1.4 V to 6 V
- Ultra-low quiescent current enabling long battery life in portable and IoT sensing applications
- Dual op-amp configuration in a single 8-pin SOIC package reduces board area and BOM cost
- 60 dB minimum CMRR for accurate differential signal processing and noise rejection
Applications
The MCP6442-E/SN is designed for low-power sensor signal conditioning in portable medical devices, IoT nodes, and battery-operated data loggers where supply current must be minimized. Its rail-to-rail swing makes it well-suited for amplifying small signals from thermistors, photodiodes, and bridge sensors on 1.8 V or 3.3 V supplies. The dual configuration simplifies two-channel amplifier designs in a single compact package.

Frequently Asked Questions
What is the gain-bandwidth product of the MCP6442-E/SN and how does this affect its use in audio or sensing circuits?
The MCP6442-E/SN has a gain-bandwidth product of 9 kHz, making it optimized for DC and very low-frequency signal conditioning rather than audio or high-frequency applications. It is well-suited for amplifying slow-changing signals from temperature sensors, pressure transducers, and electrochemical cells on 1.4 V to 6 V supplies.
What supply voltage range does the MCP6442-E/SN support and which battery chemistries are compatible?
The MCP6442-E/SN operates from a supply voltage range of 1.4 V to 6 V, covering single-cell alkaline batteries at 1.5 V, coin cells at 3 V, and two-cell alkaline or NiMH packs up to 3 V. This broad range makes it suitable for ultra-low-power IoT sensors, wearables, and environmental monitoring devices.
What is the CMRR specification of the MCP6442-E/SN and why does it matter in differential measurements?
The MCP6442-E/SN specifies a minimum common-mode rejection ratio (CMRR) of 60 dB, with a nominal value of 76 dB. Higher CMRR means the op-amp rejects supply noise and interference common to both inputs, which is critical for accurate bridge sensor readout and differential temperature measurements in noisy environments.
How many amplifier channels does the MCP6442-E/SN provide and what is its package configuration?
The MCP6442-E/SN integrates 2 independent operational amplifiers in a single 8-pin SOIC package, allowing two analog signal channels to be conditioned with one IC. This dual configuration reduces board space and simplifies routing compared to using two discrete single op-amp packages in portable sensor applications.
In what low-power embedded designs is the MCP6442-E/SN preferred over higher-bandwidth alternatives?
The MCP6442-E/SN is preferred in ultra-low-power designs such as coin-cell-powered environmental sensors, medical patches, and sub-threshold ADC front-ends where bandwidth below 9 kHz is sufficient and minimizing quiescent current is the primary design constraint. Its 1.4 V minimum supply enables direct use with discharged alkaline batteries.
