Overview
The LMC7225IM5X is a single-channel analog comparator from Texas Instruments, housed in an SOT-23-5 surface-mount package. It operates on a supply voltage ranging from 2 V to 8 V with a typical operating supply current of 1 uA. The device features rail-to-rail input capability and a push-pull output stage. Key electrical specifications include an input offset voltage (Vos) of 6 mV, an input bias current (Ib) of 50 fA, a response time of 24 us, a common-mode rejection ratio (CMRR) of 80 dB, and a power supply rejection ratio (PSRR) of 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
- Push-pull output provides strong drive capability without external pull-up resistors
Applications
- Battery-powered sensing systems
- Threshold detection circuits
- Low-voltage signal conditioning
Procurement Notes
Verify the specific suffix 'X' indicates reel packaging when ordering. Confirm the component matches the LMC7225 family specifications regarding the 50 fA bias current and 6 mV offset voltage. Ensure the SOT-23-5 footprint aligns with the target PCB design. Check RoHS compliance status through official manufacturer documentation before integration.
Selection Notes
Select this component when low quiescent current is critical alongside rail-to-rail input requirements. The push-pull output simplifies interface design compared to open-drain alternatives. Consider the 24 us response time for speed-sensitive applications. Verify that the 2 V minimum supply voltage meets the system's lowest operating condition.
Part Context
This part belongs to the LMC72xx series of micro-power CMOS comparators. It shares the SOT-23-5 form factor with other devices in the family but differs in output configuration and specific electrical parameters. The LMC7225 variant specifically offers a push-pull output, distinguishing it from open-drain counterparts like the LMC7224.
FAQ
Does the LMC7225IM5X have a shutdown pin?
No, the LMC7225 does not feature a shutdown control pin.
What is the input bias current specification?
The input bias current is specified at 50 fA.
