Frequently Asked Questions
How low is the quiescent current of the MCP609-I/SL, and how does that benefit portable designs?
Each of the 4 amplifier channels in the MCP609-I/SL draws only 25 µA of quiescent current, totaling around 100 µA for all 4 channels, which allows battery-powered sensor systems and data loggers to run for extended periods on a small Li-ion or alkaline cell.
What is the minimum supply voltage for the MCP609-I/SL, and which low-voltage rails does it support?
The MCP609-I/SL operates from a minimum single supply of 2.5 V, making it compatible with low-dropout regulators and Li-ion battery cells. It can also work with dual supplies, giving designers flexibility for both single-supply and split-rail analog signal processing circuits.
How does the MCP609-I/SL's 91 dB CMRR performance compare to general-purpose op-amps for sensor amplification?
The MCP609-I/SL achieves a typical CMRR of 91 dB and a minimum of 75 dB, which is superior to many general-purpose op-amps and allows it to effectively reject power-line and ground noise when amplifying small differential signals from bridge sensors or thermocouples.
Is the MCP609-I/SL a suitable choice for replacing a dual op-amp package when 4 channels are needed on a single chip?
Yes. Using the MCP609-I/SL consolidates 4 amplifier channels into a single 14-pin SOIC package, reducing component count, board area, and BOM cost compared to using 2 separate dual op-amp packages while maintaining the same 25 µA per-channel power budget.
