What are the key features of MCP6143T-E/CH?
- Ultra-low supply voltage operation from 1.6 V to 5.5 V suits single-cell battery designs with minimal dropout
- 5 pA maximum input bias current enables high-impedance sensor interfaces without loading error
- 100 kHz gain-bandwidth product with 62 dB minimum CMRR in compact SOT-23-6 package saving PCB space
What is MCP6143T-E/CH used for?
MCP6143T-E/CH is used in wearable health monitors and portable sensors where supply voltages as low as 1.6 V must be supported and quiescent current must be minimized. Its 5 pA input bias current makes it suitable for high-impedance pH probe amplifiers and photodiode transimpedance stages without introducing measurement error. The SOT-23-6 package is well-suited for space-constrained IoT node designs.

Frequently Asked Questions
What is the input bias current of MCP6143T-E/CH, and why does it matter for high-impedance sensor interfaces?
MCP6143T-E/CH specifies a maximum input bias current of 0.005 µA (5 pA), which produces less than 5 mV of error across a 1 GΩ source impedance. This makes it suitable for pH electrode amplifiers, photodiode transimpedance circuits, and capacitive humidity sensors where source impedances exceed 10 MΩ and error budgets are tight in battery-powered systems.
How does the 1.6 V minimum supply of MCP6143T-E/CH enable single-cell energy harvesting designs?
Operating from as low as 1.6 V, MCP6143T-E/CH functions directly from a single alkaline or NiMH cell through its full discharge cycle, which typically ends near 1.0 V to 1.2 V. This allows the op-amp to remain active in energy-harvesting IoT nodes powered by piezoelectric or thermoelectric generators that produce 1.6 V to 3.3 V, avoiding a boost converter and extending battery life by reducing quiescent current overhead.
How does MCP6143T-E/CH CMRR compare to standard general-purpose op-amps for bridge sensor measurements?
MCP6143T-E/CH achieves 80 dB typical CMRR (62 dB minimum), which is on par with general-purpose amplifiers like LM358 but in a much smaller SOT-23-6 package footprint. For a Wheatstone bridge application running from a 3.3 V supply, this CMRR rejects common-mode noise by a factor of 10,000 at DC, enabling millivolt-level bridge differential signals to be amplified accurately without external resistor matching networks.
