Key Features
- Dual comparator in a single SOIC-8 package with open-drain outputs for flexible logic-level interfacing and wired-OR configurations
- Rail-to-rail input/output (RRIO) operation across the full 9V supply range enables accurate comparisons near supply rails
- Ultralow input bias current of 0.1 nA (max) minimizes loading on high-impedance sensor sources
- RoHS-compliant (JESD-609 e3) Pb-free construction with a 7-week factory lead time and broad distributor stock
Applications
The MCP6547-I/SN is ideal for battery-powered and portable systems where low quiescent current and wide supply range are critical, such as threshold detection in sensors and battery management circuits. Its open-drain outputs allow direct interfacing with different logic voltage domains, making it suitable for level translation and interrupt generation in microcontroller-based designs. The dual-channel configuration also supports window comparator implementations for overvoltage and undervoltage monitoring.

Frequently Asked Questions
What supply voltage range does the MCP6547-I/SN support?
The MCP6547-I/SN operates over a wide supply voltage range up to 9V, making it compatible with 3.3V, 5V, and higher supply rails commonly used in industrial and consumer electronics designs.
What is the input bias current and offset voltage of the MCP6547-I/SN?
The device specifies a maximum average input bias current (IIB) of 0.1 nA (100 pA), which is extremely low, and a maximum input offset voltage of 7000 µV (7 mV), ensuring reliable threshold detection in precision analog applications.
What does the open-drain output mean for the MCP6547-I/SN?
Open-drain outputs require an external pull-up resistor to the desired logic voltage, allowing the MCP6547-I/SN to interface with multiple logic levels (e.g., 1.8V, 3.3V, 5V) and support wired-OR bus configurations in embedded systems.
What package is the MCP6547-I/SN available in and is it lead-free?
It comes in a standard SOIC-8 package (JESD-30 code R-PDSO-G8). The JESD-609 code e3 confirms it is lead-free and RoHS compliant, with the Pb-free code indicating it meets environmental regulations for global distribution.
What are typical use cases for the MCP6547-I/SN dual comparator?
Common applications include voltage threshold detection, window comparators for overvoltage/undervoltage protection, zero-crossing detectors, sensor signal conditioning, and battery charge-level monitoring in IoT, industrial, and portable consumer devices.
