Overview
The LMC7211BIMX/NOPB is a single-channel analog comparator from 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 operating current of 14 µA. The device features a push-pull output capable of sourcing or sinking 45 mA. Key electrical parameters include a maximum response time of 4 µs, an input offset voltage (Vos) of 5 mV, and an input bias current (Ib) of 0.4 pA. Common-mode rejection ratio (CMRR) is specified at 75 dB, while power supply rejection ratio (PSRR) is 80 dB. It functions within a temperature range of -40°C to +85°C.
Feature Summary
- Low-power CMOS architecture designed for minimal energy consumption
- High-voltage operation capability supporting wide supply ranges
- Push-pull output stage providing robust drive strength
Applications
- General-purpose signal comparison circuits
- Battery-powered systems requiring low quiescent current
- Threshold detection applications
Procurement Notes
Verify the specific suffix 'BIMX/NOPB' against the manufacturer's datasheet to confirm the SOIC-8 package and lead-free status. Ensure the ordering quantity aligns with available packaging options such as cut tape or reel. Confirm that the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the Mouser number 926-LMC7211BIMX/NOPB for accurate distributor identification.
Selection Notes
Select this component when a general-purpose comparator with ultra-low input bias current is required. The 14 µA supply current makes it suitable for battery-operated devices where power efficiency is critical. The push-pull output eliminates the need for external pull-up resistors in many configurations. Consider the 4 µs propagation delay for timing-sensitive applications.
Part Context
This part belongs to the LMC7211 series of low-power high-voltage comparators manufactured by Texas Instruments. It is part of the broader family of linear integrated circuits designed for precision analog signal processing. The device serves as a standalone solution for voltage threshold monitoring without requiring complex external circuitry.
Replacement Considerations
The LMC7211BIM/NOPB is listed as a similar product with tube packaging instead of reel/cut tape. Verify pin compatibility and electrical specifications before substitution.
