Overview
The LMC7225IM5 is a single-channel analog comparator from Texas Instruments, housed in an SOT-23-5 surface-mount package. It operates on a supply voltage range of 2 V to 8 V with a typical operating supply current of 1 uA. The device features rail-to-rail input capability and an open-drain output type. Key electrical specifications include an input offset voltage (Vos) of 6 mV, an input bias current (Ib) of 50 fA, and a response time of 24 us. Common-mode rejection ratio (CMRR) is 80 dB, while power-supply rejection ratio (PSRR) is 90 dB. It functions within a temperature range of -40°C to +85°C.
Feature Summary
- Ultra-low power consumption suitable for battery-operated applications
- Rail-to-rail input stage allows operation near supply rails
- Open-drain output configuration provides flexibility in logic interfacing
Applications
- Battery-powered monitoring systems
- Threshold detection circuits
- Low-voltage signal conditioning
Procurement Notes
Verify the specific suffix against the manufacturer's official documentation to confirm pinout and electrical characteristics match the required design specifications. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability. Check for RoHS compliance status as indicated in the latest datasheet revision.
Selection Notes
Select this component when low quiescent current is critical and rail-to-rail input compatibility is required. The open-drain output necessitates an external pull-up resistor; ensure the chosen resistor value aligns with the desired switching speed and load requirements. Verify that the 24 us response time meets the application's timing constraints.
Part Context
This part belongs to the LMC72xx series of low-power comparators designed for portable electronics. It shares the SOT-23-5 footprint with other devices in the family but differs in output stage configuration. Unlike push-pull variants, this model offers open-drain output, requiring different circuit design considerations for interfacing with downstream logic levels.
FAQ
What is the output configuration of the LMC7225IM5?
The LMC7225IM5 features an open-drain output, which requires an external pull-up resistor to function correctly.
Does the LMC7225IM5 support rail-to-rail inputs?
Yes, the device supports rail-to-rail input operation, allowing it to detect signals close to the positive and negative supply rails.
