Overview
The LMC7225IM5X/NOPB is a single-channel analog comparator from Texas Instruments, housed in an SOT-23-5 surface-mount package. It operates within a supply voltage range of 2 V to 8 V and draws a typical operating supply current of 1 µA. Key electrical specifications include a maximum input offset voltage (Vos) of 6 mV and an input bias current (Ib) of 50 fA. The device features an open-drain output type and supports general-purpose applications across a temperature range of -40°C to +85°C.
Feature Summary
- Ultra-low power consumption with 1 µA operating supply current
- High precision performance characterized by 6 mV maximum input offset voltage
- Extremely low input bias current of 50 fA for minimal circuit loading
- Open-drain output configuration suitable for various logic interfacing
Applications
- Battery-powered portable instrumentation
- Low-voltage signal conditioning circuits
- Threshold detection systems requiring minimal quiescent current
- Precision sensor interface applications
Procurement Notes
Verify the specific suffix 'X' indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure the open-drain output requirement matches the target application's pull-up resistor design. Validate that the 2 V minimum supply voltage aligns with the system's power rails.
Selection Notes
Select this component when ultra-low quiescent current is critical compared to standard comparators. The open-drain output requires external pull-up components, unlike push-pull alternatives. Consider the 6 mV Vos limit for high-precision threshold applications. The SOT-23-5 package offers space efficiency for compact designs.
Part Context
This part belongs to the LMC7225 series of micropower comparators. It shares the family's focus on low voltage operation and tiny footprint. Unlike the LMC7215 which features push-pull outputs, this variant provides open-drain functionality. It serves as a specialized solution for battery-operated devices where power conservation is paramount.
FAQ
What is the output configuration of the LMC7225IM5X/NOPB?
The device features an open-drain output, requiring an external pull-up resistor to define the high logic level.
Does the LMC7225 support shutdown mode?
No, the LMC7225 does not include a shutdown pin or feature; it operates continuously when powered.
