What are the key features of MCP619-I/P?
- Quad op-amp (4 amplifiers) with PNP input stage for single 2.3 V supply operation
- Ultra-low 5 nA maximum input bias current for high-impedance sensor interfaces
- 100 dB typical CMRR, 80 dB minimum for noise-rejection in differential measurements
- Rail-to-rail output for maximum dynamic range on low-voltage supplies
- 14-pin PDIP package, RoHS-compliant (Pb-free)
What is MCP619-I/P used for?
MCP619-I/P is well-suited for portable medical instruments, battery-powered data loggers, and handheld test equipment where 4 op-amp channels must operate from a 2.3 V to 6 V single supply with minimal quiescent current. The low input bias current and high CMRR make it particularly effective for interfacing pH electrodes, thermocouples, and bridge-based pressure sensors in precision measurement applications.

Frequently Asked Questions
What is the minimum supply voltage for MCP619-I/P and can it run from a single AAA battery cell?
MCP619-I/P operates from a minimum single-supply voltage of 2.3 V, which is above a single AAA alkaline cell's end-of-discharge voltage of about 1.0 V but within range for two cells in series (about 3 V nominal), making it usable in 2-cell battery instruments with careful power management.
How does MCP619-I/P's 5 nA input bias current benefit high-impedance sensor interfaces such as pH probes?
pH electrodes and similar high-impedance sensors have source impedances in the range of 100 MΩ to 1 GΩ. With a maximum input bias current of 0.005 µA (5 nA), MCP619-I/P introduces less than 0.5 mV of offset error even across a 100 MΩ source impedance, preserving measurement accuracy without buffer transistors.
What CMRR performance does MCP619-I/P deliver in a differential measurement circuit under 50 Hz/60 Hz mains noise conditions?
MCP619-I/P achieves a typical CMRR of 100 dB and a minimum of 80 dB, attenuating 50 Hz or 60 Hz common-mode mains interference by a factor of at least 10,000. This level of rejection is suitable for industrial weigh-scale front ends and thermocouple amplifiers operating near power wiring.
What lead time and package should procurement teams expect for MCP619-I/P, and is a surface-mount alternative available?
MCP619-I/P is supplied in a 14-pin PDIP package with a factory lead time of approximately 6 weeks. Procurement teams requiring SMT assembly should consider the MCP619-E/SL variant in a 14-pin SOIC package, which is pin-compatible and available in tape-and-reel format for volume orders.
