Overview
The LMC7211AIMX/NOPB is a single-channel analog comparator from Texas Instruments, housed in an SOIC-8 surface-mount package. It operates on a supply voltage ranging from 2.7 V to 15 V with a typical operating current of 14 uA. The device features a push-pull output and a response time of 4 us. 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
- Ultra-low power consumption suitable for battery-operated applications
- High input impedance with extremely low input bias current
- Push-pull output stage for direct interfacing with digital logic
Applications
- Battery-powered monitoring systems
- Threshold detection circuits
- General-purpose signal comparison
Procurement Notes
Verify the complete part number including suffixes such as NOPB and MX against official Texas Instruments documentation to ensure correct packaging and lead-free compliance. Confirm that the SOIC-8 package variant matches your PCB footprint requirements. Cross-reference the specific revision level if critical for long-term production stability.
Selection Notes
Select this component when low quiescent current is prioritized over high-speed performance. The 4 us response time limits suitability for high-frequency applications compared to faster comparators. Ensure the design accommodates the -200 mV common-mode voltage range if signals approach or go slightly below ground potential.
Part Context
This device belongs to the LMC7211 series of low-power CMOS comparators manufactured by Texas Instruments. It is designed to provide high input impedance and low power dissipation in a compact surface-mount format. The series is intended for general-purpose analog-to-digital interface tasks where power efficiency is a primary constraint.
Replacement Considerations
Consult official substitution guides for pin-compatible alternatives within the Texas Instruments portfolio. Verify that any substitute maintains the required 14 uA current draw and 4 us response time characteristics.
