Overview
The LMC7221BIM5/NOPB is a single-channel analog comparator manufactured by 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 an open-drain output type and a general-purpose classification. Key electrical parameters include a response time of 24 us, an input bias current (Ib) of 50 fA, and an input offset voltage (Vos) of 6 mV. It functions within a temperature range of -40 C to +125 C.
Feature Summary
- Ultra-low power consumption suitable for battery-operated applications
- Rail-to-rail input capability for maximum dynamic range
- Open-drain output configuration allowing flexible logic interfacing
Applications
- Battery-powered monitoring systems
- Threshold detection circuits
- Low-power signal conditioning
Procurement Notes
Verify the specific suffix 'M5' corresponds to the SOT-23-5 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the open-drain output requirement matches the target circuit design specifications.
Selection Notes
Select this component for designs requiring minimal quiescent current and rail-to-rail input compatibility. The open-drain output necessitates an external pull-up resistor; verify the required voltage level and resistance value for the specific application logic interface. Consider the 24 us propagation delay for timing-sensitive applications.
Part Context
This part belongs to the LMC722x series of low-power comparators from Texas Instruments. It shares architectural similarities with other members like the LMC7211 but differs in output stage configuration and specific package availability. The series is designed for high-impedance sensing applications where power efficiency is critical.
Replacement Considerations
LMC7221IM5/NOPB: Pin-compatible alternative with potentially different initial offset voltage specifications.
