What are the key features of MCP616-I/SN?
- Ultra-low input bias current of 5 nA maximum enables accurate high-impedance sensor signal conditioning
- 100 dB typical common-mode rejection ratio (CMRR) ensures excellent noise immunity in differential signal paths
- Single-supply voltage-feedback op-amp architecture in compact 8-pin SOIC for space-efficient analog designs
What is MCP616-I/SN used for?
The MCP616-I/SN is suited for precision sensor amplification in battery-powered instruments, photodiode transimpedance amplifiers, and high-impedance pH or electrochemical sensor interfaces where the 5 nA bias current minimizes measurement error. Its 100 dB CMRR makes it effective in differential signal conditioning for bridge sensor circuits, strain gauges, and Wheatstone bridge amplifiers requiring high common-mode noise rejection. The 8-pin SOIC package fits standard analog front-end PCB layouts in industrial and medical measurement equipment.

Frequently Asked Questions
How does the 5 nA input bias current of MCP616-I/SN benefit high-impedance sensor designs?
With a maximum input bias current of only 5 nA at 25°C, the MCP616-I/SN introduces negligible voltage error across source impedances up to 10 MΩ — less than 50 mV offset — making it ideal for pH sensors, photodiodes, and other high-impedance transducers where even modest bias current causes significant measurement inaccuracy.
In a Wheatstone bridge sensor circuit, what noise rejection does the MCP616-I/SN common-mode rejection ratio provide?
The MCP616-I/SN achieves a minimum CMRR of 80 dB and a typical CMRR of 100 dB, attenuating common-mode noise such as 50 Hz or 60 Hz power-line interference by a factor of 100,000 typical. This makes it reliable in bridge amplifier circuits for strain gauges and pressure sensors operating near noisy power supplies.
What supply voltage range does the MCP616-I/SN support for single-supply portable designs?
The MCP616-I/SN operates from a single supply of 2.5 V to 5.5 V, covering both 3.3 V and 5 V embedded systems. It also supports a split supply of ±1.25 V to ±2.75 V, giving designers flexibility to use it in battery-powered equipment with a 3 V or lower rail without additional level-shifting circuitry.
How does MCP616-I/SN compare to a standard general-purpose op-amp for a precision data acquisition front-end?
Compared to a general-purpose op-amp with typical bias currents of 100 nA or more, the MCP616-I/SN's 5 nA maximum bias current reduces input offset voltage error by a factor of 20× in high-impedance sensor channels. Combined with its 100 dB CMRR, it provides precision-grade performance suitable for 12-bit to 16-bit ADC front ends without requiring a dedicated instrumentation amplifier.
