Overview
The LMC7211BIM5/NOPB is a single-channel, general-purpose analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 15 V and consumes a typical operating supply current of 14 µA. The device features rail-to-rail input capability with an input offset voltage of 15 mV and an input bias current of 0.4 pA. It utilizes a push-pull output configuration and is housed in a SOT-23-5 package. Key electrical parameters include a response time of 4 µs, a common-mode rejection ratio (CMRR) of 75 dB, and a power supply rejection ratio (PSRR) of 80 dB. The component functions reliably across an extended temperature range from -40°C to +85°C.
Feature Summary
- Rail-to-rail input stage enables operation with input signals extending to the supply rails.
Applications
- General purpose signal comparison
- Threshold detection circuits
Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status through the latest datasheet revision. Ensure the SOT-23-5 package marking matches the intended design requirements. Validate that the operating temperature range meets the environmental specifications of the target application.
Selection Notes
Select this component for applications requiring low power consumption and wide supply voltage flexibility. The rail-to-rail input feature makes it suitable for single-supply systems where signal levels approach ground or VCC. Consider the 14 µA quiescent current for battery-operated designs. Verify that the 4 µs response time aligns with the required switching speed of the system.
Part Context
This part belongs to the LMC7211 series of tiny CMOS comparators. It is designed as a cost-effective solution for space-constrained applications. The device integrates a single comparator channel into a compact five-pin surface-mount package. It serves as a standalone alternative to operational amplifiers used in comparator mode, offering optimized performance for threshold detection tasks.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Verify pin compatibility and electrical parameter equivalence before replacing the component.
