Overview
The LMC7221BIM/NOPB 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 2.7 V to 15 V with a typical quiescent current of 14 µA. The device features rail-to-rail input capability and an open-drain output configuration. Key electrical specifications include a response time of 4 µs, an input offset voltage (Vos) of 5 mV, and an input bias current (Ib) of 0.4 pA. Additional parameters include a common-mode rejection ratio (CMRR) of 75 dB and a power supply rejection ratio (PSRR) of 80 dB. It functions within a temperature range of -40°C to +85°C.
Feature Summary
- Low-power CMOS architecture designed for battery-operated applications
- Rail-to-rail input stage allows operation near ground and positive supply rails
- Open-drain output facilitates direct interfacing with digital logic families
Applications
- Battery-powered monitoring systems
- Threshold detection circuits
- General-purpose signal comparison
Procurement Notes
Verify the specific suffix 'BIM' against the manufacturer's official documentation to confirm pinout and electrical tolerances match design requirements. Ensure the SOIC-8 package dimensions align with PCB footprint constraints. Confirm RoHS compliance status through the latest datasheet revision notes before finalizing procurement orders.
Selection Notes
Select this component when low supply current is critical and rail-to-rail input compatibility is required. The open-drain output necessitates an external pull-up resistor; ensure the selected resistor value supports the target logic voltage levels. Compare performance against push-pull output alternatives if drive strength without external components is necessary.
Part Context
This part belongs to the LMC7221 series of low-power high-voltage comparators from Texas Instruments. It shares architectural similarities with other members of the family but differs in specific output configurations and packaging options. The series is designed to replace older bipolar comparator technologies in modern low-power designs.
Replacement Considerations
LMC7221AIMX/NOPB: Similar general-purpose comparator with identical electrical characteristics but potentially different manufacturing lot or minor parameter variations.
