What are the key features of MCP619-I/SL?
- Single-supply operation from 2.3 V to 5.5 V with rail-to-rail output swing enabling use in battery-powered and 3.3 V systems
- Ultra-low input bias current of 5 nA maximum allowing high-impedance sensor interfacing without loading errors
- 100 dB typical CMRR and 80 dB minimum ensuring excellent noise rejection in sensor bridge and instrumentation amplifier circuits
- Quad op-amp in a 14-pin SOIC package reducing per-channel cost and board area compared to four single-channel devices
What is MCP619-I/SL used for?
The MCP619-I/SL is used in single-supply sensor signal conditioning circuits for pH electrodes, photodiodes, and resistive bridge sensors where sub-microamp input bias currents are essential. Its rail-to-rail output swing maximizes dynamic range in 3.3 V portable measurement instruments and data loggers. Active filter stages, transimpedance amplifiers, and summing amplifiers in industrial process control equipment also benefit from its wide supply range and high CMRR.

Frequently Asked Questions
What input bias current spec makes the MCP619-I/SL suitable for high-impedance sensor interfaces?
The MCP619-I/SL specifies a maximum input bias current of 5 nA at 25°C, which causes less than 5 µV of offset error even with a 1 kohm source impedance. This makes it appropriate for pH electrode buffers, photodiode transimpedance stages, and resistive humidity sensor front-ends where source impedances reach 100 kohm to 10 Mohm.
How does the 2.3 V to 5.5 V supply range of the MCP619-I/SL benefit a dual-supply 3.3 V design?
Running from a single 3.3 V rail within the 2.3 V to 5.5 V specified range, the MCP619 eliminates the need for a negative supply in most sensor conditioning circuits. The rail-to-rail output swings within approximately 20 mV of each rail at light loads, preserving nearly the full 3.3 V dynamic range for downstream 12-bit ADC inputs.
What CMRR performance does the MCP619-I/SL deliver in a differential measurement application?
The MCP619-I/SL achieves a typical CMRR of 100 dB with a guaranteed minimum of 80 dB, attenuating common-mode noise by a factor of 100,000. In a Wheatstone bridge measurement with 50 mV full-scale differential signal riding on a 1.65 V common-mode level, 80 dB CMRR limits the common-mode error contribution to under 0.5 µV referred to input.
For a 4-channel active low-pass filter design, how does the MCP619-I/SL SOIC-14 compare to using four single op-amps?
The quad MCP619-I/SL in a 14-pin SOIC occupies roughly 8.65 mm x 3.9 mm for all 4 channels, versus four separate SOT-23-5 single op-amps occupying approximately 4 times 2.9 mm x 1.6 mm plus routing clearance. The single-package solution typically reduces board area by 40% to 50% and cuts hand-placement time in low-volume assembly.
