What are the key features of MCP6561RT-E/OT?

  • Single comparator with 1.8V minimum supply voltage and only 5 nA maximum bias current, ideal for ultra-low-power battery-operated applications
  • Push-pull output stage enabling direct logic-level interfacing with microcontrollers without an external pull-up resistor
  • Compact 5-pin SOT-23 package occupying minimal PCB area for space-constrained wearable and IoT sensor designs

What is MCP6561RT-E/OT used for?

The MCP6561RT-E/OT is designed for threshold detection, zero-crossing sensing, and window comparator circuits in portable medical devices, wearables, and IoT sensors where supply current must remain in the nanoamp range. Its 1.8V minimum supply and push-pull output make it a direct-fit solution for battery-powered systems powered by a single Li-ion cell or two AAA alkaline batteries.

Frequently Asked Questions

What is the minimum supply voltage for the MCP6561RT-E/OT, and does it support single-cell Li-ion systems?

The MCP6561RT-E/OT operates from as low as 1.8V, which is well within the discharge curve of a single Li-ion cell (typically 3V to 4.2V fully charged), making it suitable for single-cell battery applications without a boost converter.

How low is the bias current of the MCP6561RT-E/OT, and why is that critical for battery-powered comparator designs?

The maximum input bias current is 0.005 µA (5 nA), which contributes negligible quiescent drain in always-on monitoring circuits, extending battery life significantly compared to comparators with microamp-level bias currents.

Does the MCP6561RT-E/OT require a pull-up resistor at its output when connected to a 3.3V microcontroller GPIO?

No, the MCP6561RT-E/OT has a push-pull output that actively drives both high and low states, eliminating the need for an external pull-up resistor and simplifying PCB routing when interfacing with 3.3V microcontroller input pins.

What input offset voltage does the MCP6561RT-E/OT specify, and how does that affect precision threshold detection?

The maximum input offset voltage is 10,000 µV (10 mV), which defines the minimum detectable voltage difference at the comparator inputs; for applications requiring tighter thresholds below 10 mV, a lower-offset comparator should be considered instead.
