Overview
The LMC7215IM/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 µA. Key electrical specifications include a maximum input offset voltage (Vos) of 8 mV and an input bias current (Ib) of 0.05 pA. The device features rail-to-rail input capability and provides a push-pull output. It offers a common-mode rejection ratio (CMRR) of 80 dB and a power supply rejection ratio (PSRR) of 90 dB. The component 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 configuration eliminates need for external pull-up resistors
Applications
- Low voltage threshold detection circuits
- Battery-powered monitoring systems
- General-purpose signal comparison tasks
Procurement Notes
Verify the specific suffix 'IM' indicates the standard tape-and-reel packaging variant distinct from the 'IM5X' cut-tape version. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected distributor source aligns with the exact part number designation to avoid functional discrepancies related to packaging or revision levels.
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. Verify that the 8 mV maximum input offset voltage meets the precision requirements of the specific application circuit. Ensure the 8 V maximum supply voltage constraint fits within the system power budget.
Part Context
This device belongs to the LMC7215 series of low-power CMOS comparators. It shares architectural similarities with other members like the LMC7211 but differs in supply voltage ranges and specific performance metrics. The family targets portable electronics where power efficiency and small form factor are prioritized over high-speed switching capabilities.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided reference data.
