Overview
The LMC7215IM is a single-channel analog comparator manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It operates on a supply voltage range of 2 V to 8 V with a typical operating supply current of 1 µA. The device features a push-pull output capable of sourcing or sinking up to 30 mA per channel. Key electrical specifications include a response time of 24 µs, an input offset voltage (Vos) of 6 mV, and an input bias current (Ib) of 0.05 pA.
Feature Summary
- Ultra-low power consumption suitable for battery-operated applications
- Push-pull output stage providing high drive capability
- High input impedance with minimal bias current
Applications
- General purpose signal comparison
- Threshold detection circuits
- Low-power monitoring systems
Procurement Notes
Verify the specific suffix 'NOPB' when ordering, as it indicates lead-free compliance and RoHS adherence. Confirm the package type is SOIC-8 and ensure the manufacturer is Texas Instruments. Cross-reference the full part number LMC7215IM/NOPB with official distributor catalogs to ensure correct component identification before procurement.
Selection Notes
Select this component when low quiescent current is critical alongside moderate speed requirements. The push-pull output eliminates the need for external pull-up resistors compared to open-drain alternatives. Ensure the application voltage stays within the 2 V to 8 V range and that the 24 µs response time meets the system timing constraints.
Part Context
This device belongs to the LMC72xx series of ultra-low power comparators from Texas Instruments. It shares similar performance characteristics with other members like the LMC7225 but differs in output configuration. The series is designed for applications requiring minimal power draw while maintaining functional accuracy in portable and battery-powered electronic devices.
Replacement Considerations
The LMC7225IM5-NOPB is a related alternative offering open-drain output instead of push-pull. Verify if the circuit design can accommodate the required pull-up resistor for the open-drain variant. Both devices share similar power and speed specifications.
