Overview
The LMC7211AIM/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 operating supply current of 14 µA. The device features a push-pull output and a response time of 4 µs. Key electrical specifications include an input offset voltage (Vos) of 5 mV, an input bias current (Ib) of 0.4 pA, a common-mode rejection ratio (CMRR) of 75 dB, and a power supply rejection ratio (PSRR) of 80 dB. The common-mode voltage extends to -200 mV below ground. It functions within a temperature range of -40°C to +85°C.
Feature Summary
- Low power consumption with ultra-low input bias current
- High voltage operation capability up to 15 V
- Push-pull output stage for direct interfacing
Applications
- General purpose analog signal comparison
- Battery-powered low power systems
- Threshold detection circuits
Procurement Notes
Verify the specific suffix 'N' indicates lead-free status and RoHS compliance as per manufacturer documentation. Confirm the 'IM' designation corresponds to the industrial temperature range (-40°C to +85°C) and SOIC-8 package variant. Ensure ordering details match the exact part number LMC7211AIM/NOPB to avoid confusion with other pinouts or performance grades within the LMC7211 family.
Selection Notes
Select this component when a general-purpose comparator requires low quiescent current and high-voltage tolerance. The push-pull output eliminates the need for external pull-up resistors compared to open-drain alternatives. Consider the 4 µs propagation delay for timing-sensitive applications. Verify that the 5 mV offset voltage meets the precision requirements of the specific circuit design.
Part Context
This part belongs to the LMC7211 series of low-power, high-voltage comparators from Texas Instruments. It is designed for applications requiring minimal power consumption while maintaining compatibility with standard logic levels through its push-pull output. The series offers a balance between speed and power efficiency suitable for portable and battery-operated devices.
Replacement Considerations
Consult official substitution guides for equivalent parts within the same family or cross-reference with other manufacturers offering similar low-power, high-voltage comparator specifications.
