Applications
The MCP616-I/P is designed for low-power sensor signal conditioning, precision integrators, and active low-frequency filters in battery-operated instruments and IoT sensor nodes powered by 3.3 V or 5 V supplies. Its ultra-low quiescent current and rail-to-rail output make it well-suited for weigh-scale front-ends, pH electrode amplifiers, and other high-impedance transducer interfaces where minimizing power draw is critical.

Frequently Asked Questions
What DC precision does MCP616-I/P offer for a pH electrode amplifier that needs sub-millivolt offset accuracy?
The MCP616-I/P provides a maximum input offset voltage of 2 mV and a typical common-mode rejection ratio of 100 dB, making it suitable for pH electrode front-ends where electrode outputs range from 0 to 500 mV. The 5 nA input bias current causes negligible offset error across the high-impedance glass electrode source impedance.
How does MCP616-I/P's 190 kHz gain-bandwidth product limit the maximum useful gain for audio-frequency sensor circuits?
With a 190 kHz gain-bandwidth product, the MCP616-I/P supports closed-loop gains of 10 up to about 19 kHz and gains of 100 up to about 1.9 kHz. This suits low-frequency audio, thermocouple amplification, and strain-gauge readout stages below 10 kHz, but is insufficient for high-bandwidth audio or RF signal conditioning.
For a wearable ECG monitor on a 3 V coin cell, how does MCP616-I/P's supply range and quiescent current affect device runtime?
The MCP616-I/P operates from 2.5 V to 5.5 V, covering the usable 3 V CR2032 discharge range. Its very low quiescent current — typically 26 µA — means a 225 mAh CR2032 can supply the amplifier alone for roughly 8600 hours, making it practical for long-lifetime wearable sensor front-ends.
When would a designer switch from MCP616-I/P in PDIP-8 to a surface-mount package for production?
Designers move from PDIP-8 to SMT packages when PCB real estate is limited or automated pick-and-place is preferred for volume production. Microchip offers the MCP616T-I/SN in SOIC-8 (4.9 mm × 3.9 mm body) and the MCP616T-I/ST in TSSOP-8 (4.4 mm × 3.0 mm body) as direct pin-compatible SMT alternatives.
