Overview
The LMC7211AIM5X/NOPB is a single-channel analog comparator manufactured by Texas Instruments, housed in an SOT-23-5 surface-mount package. It operates on a single or dual power supply ranging from 2.7V to 15V. Key electrical specifications include a maximum input offset voltage of 5mV at 5V, a typical quiescent current of 14µA, and a maximum propagation delay of 10µs. The device features rail-to-rail inputs, a push-pull output capable of sourcing 30mA, and maintains a common-mode rejection ratio of 75dB and power supply rejection ratio of 80dB. It functions within a temperature range of -40°C to 85°C.
Feature Summary
- Features rail-to-rail input capability for extended signal range utilization.
- Delivers high input impedance with extremely low input bias current.
- Provides push-pull output stage for direct interfacing with digital logic.
Applications
- Battery-powered monitoring systems requiring low quiescent current
- Threshold detection circuits in industrial instrumentation
- Voltage level shifting between different logic families
Procurement Notes
Verify the specific suffix configuration against the manufacturer's latest documentation, as packaging options such as tape and reel or cut tape may vary. Confirm RoHS compliance status and ensure the component meets environmental regulations for the intended deployment region. Cross-reference the ordering part number with official distributor catalogs to validate availability and authenticity before finalizing procurement orders.
Selection Notes
Select this component when designing circuits that require precise voltage comparison with minimal power consumption. The low input bias current makes it suitable for high-impedance sensor interfaces. Ensure the supply voltage remains within the specified 2.7V to 15V range and verify that the required propagation delay does not exceed 10µs for the application timing constraints.
Part Context
This device belongs to the LMC7211 series of low-power, high-voltage CMOS comparators. It is designed to offer performance comparable to bipolar comparators while consuming significantly less power. The family includes variants with different packaging options, such as SOIC-8 and SOT-23-5, catering to various space-constrained PCB layouts.
Replacement Considerations
LMC7211AIM5X/NOPB serves as a lead-free variant of the LMC7211AIM5X. Verify pin compatibility and electrical parameters against other members of the LMC7211 family if substituting with non-NOPB versions.
FAQ
What is the maximum input bias current for this comparator?
The maximum input bias current is 0.04pA at 5V, providing very high input impedance.
Does the LMC7211AIM5X/NOPB support rail-to-rail operation?
Yes, the device supports rail-to-rail inputs, allowing it to process signals close to the supply rails.
