Overview
The LMC7211AIMX 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 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, and it functions within a temperature range of -40 C to +85 C.
Feature Summary
- Low power consumption suitable for battery-operated applications
- High input impedance with minimal input bias current
- Rail-to-rail input capability extending below ground potential
Applications
- Battery-powered monitoring systems
- General-purpose signal comparison circuits
- Threshold detection in low-power instrumentation
Procurement Notes
Verify the complete part number including suffixes such as NOPB or MX against official Texas Instruments documentation to ensure correct packaging and RoHS compliance. Confirm that the specific variant matches the required operational temperature range and package type for your design constraints.
Selection Notes
Select this component when low quiescent current and high input impedance are critical requirements. Ensure the application voltage does not exceed the 15 V maximum limit. Consider the 4 us response time for speed-sensitive designs and verify that the push-pull output stage meets the load driving requirements of the downstream circuitry.
Part Context
This device belongs to the LMC7211 series of precision analog comparators from Texas Instruments. It is designed to offer high performance in low-power environments, distinguishing itself through ultra-low input bias current and wide common-mode voltage range compared to standard comparator alternatives.
Replacement Considerations
Consult official cross-reference guides for direct replacements. Verify pin compatibility and electrical parameter equivalence before substituting.
