Product details
Overview
LMC7211AIM5X/NOPB from Texas Instruments is a micropower CMOS comparator in SOT-23-5 package, featuring rail-to-rail input voltage range beyond V− and V+, push-pull output capable of sourcing/sinking ≥4.8V/0.4V at 5V supply with 5mA load, 7μA typical supply current at 5V, and 420ns propagation delay (low-to-high) under 100mV overdrive. It serves as a precision signal-level decision device in battery-powered sensor interface circuits.
For engineers reviewing the LMC7211AIM5X/NOPB datasheet, LMC7211AIM5X/NOPB pinout, LMC7211AIM5X/NOPB application, or LMC7211AIM5X/NOPB equivalent, key selection criteria include ultra-low quiescent current, rail-to-rail input operation down to 2.7V, push-pull output drive capability without external pull-up, and validated performance across −40°C to +85°C for portable electronics design.
Technical Context
The LMC7211AIM5X/NOPB implements a CMOS input stage enabling input common-mode voltage range extending 0.3V beyond both supply rails, supporting direct sensing of signals near V+ or ground in single-supply systems. Its push-pull output stage delivers logic-compatible high/low levels without external components, eliminating need for pull-up resistors in digital interfacing.
Specified across 2.7V, 5V, and 15V supplies, it maintains 5mV (NAI grade) or 15mV (NBI grade) input offset voltage with <1.0μV/°C drift at 5V, and achieves 75–82dB common-mode rejection ratio depending on supply voltage-critical for noise-immune analog threshold detection in mixed-signal environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 15V - supports operation across depleted battery voltages and standard logic rails without level-shifting. |
| Input Offset Voltage (NAI) | 5mV max - enables accurate threshold detection with ≤10mV hysteresis design margin in low-voltage sensor comparators. |
| Supply Current (Typ) | 7μA at 5V - extends battery life in always-on monitoring circuits; reduces thermal load in dense PCB layouts. |
| Propagation Delay (tPLH) | 420ns at 5V, 100mV overdrive - sufficient for slow-to-moderate speed control loops and status change detection. |
| Output Drive (VOH/VOL) | 4.8V/0.2V min/max at 5V, 5mA - directly interfaces with TTL/CMOS inputs without external pull-up or level translation. |
| Input Common-Mode Range | V− −0.3V to V+ +0.3V - allows direct connection to sensors operating at supply rails (e.g., battery voltage monitors). |
| ESD Tolerance | 2kV HBM - meets basic handling requirements for assembly in non-ESD-controlled environments. |

SOT-23-5 surface-mount package (3.05mm × 3.00mm × 1.43mm), RoHS-compliant, NIPDAU/SN lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Push-pull output | Active high/low digital output; sinks up to 45mA, sources up to 30mA; no external pull-up required. |
| 2 (−IN) | Inverting input | High-impedance CMOS node (0.04pA typical bias current); accepts signals beyond supply rails. |
| 3 (V−) | Negative supply / ground | Reference for single-supply operation; supports true ground-referenced inputs and outputs. |
| 4 (+IN) | Non-inverting input | High-impedance CMOS node; identical electrical characteristics to −IN; enables flexible threshold configuration. |
| 5 (V+) | Positive supply | Accepts 2.7V–15V; powers internal circuitry and defines output swing limits. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input range beyond supplies | Enables direct sensing of battery voltage, current-sense resistor drops, or optical sensor outputs without front-end amplifiers or dividers. |
| Push-pull output stage | Eliminates need for external pull-up resistors in microcontroller interrupt or LED driver applications, reducing BOM count and board area. |
| 7μA typical supply current | Supports >1-year operation on coin-cell batteries in wake-on-event sensor nodes; lowers self-heating in thermally constrained enclosures. |
| 2.7V minimum supply voltage | Ensures reliable operation through full discharge cycle of 3V lithium primary cells or two alkaline cells in series. |
| 5mV max input offset (NAI grade) | Permits precise window-comparator designs with ≤10mV hysteresis using only passive feedback, avoiding trimming components. |
Applications
| Battery Voltage Monitor | Optical Sensor Threshold Detector |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMC7221AIM5X/NOPB | Open-drain output; identical SOT-23-5 package and input specs; requires external pull-up for high-level output. | Used where output must interface with higher-voltage logic (e.g., 5V MCU while comparator runs at 3.3V). | Select when mixed-voltage interfacing is required; avoid if push-pull drive or reduced component count is critical. |
| TLV3701IDBVR | 360ns tPLH at 5V; 550nA supply current; rail-to-rail input; open-drain output; same SOT-23-5 package. | Ultra-low power applications where 7μA is excessive but open-drain is acceptable (e.g., energy-harvesting sensors). | Choose for sub-1μA systems; verify compatibility with downstream logic input requirements due to open-drain limitation. |
Compared with LMC7211AIM5X/NOPB, LMC7221AIM5X/NOPB trades push-pull drive for voltage-level flexibility, while TLV3701IDBVR sacrifices output drive strength to achieve 99% lower supply current-making each suitable for distinct low-power architecture trade-offs.

FAQ
What is the maximum supply voltage rating for the LMC7211AIM5X/NOPB?
The LMC7211AIM5X/NOPB has an absolute maximum supply voltage (V+ − V−) of 16V. Continuous operation is specified from 2.7V to 15V per the Electrical Characteristics tables. Exceeding 16V risks permanent damage to the device, and operation above 15V voids guaranteed performance specifications.
Does the LMC7211AIM5X/NOPB support true rail-to-rail input operation?
Yes, the LMC7211AIM5X/NOPB supports input common-mode voltage range from V− −0.3V to V+ +0.3V, verified across 2.7V, 5V, and 15V supplies. This allows direct connection of sensors producing signals at or slightly beyond the supply rails-such as battery voltage monitoring or current-sense amplifier outputs-without attenuation or level-shifting circuitry.
What is the output configuration of the LMC7211AIM5X/NOPB and how does it differ from open-drain comparators?
The LMC7211AIM5X/NOPB features a push-pull output stage capable of actively driving both high and low logic states. Unlike open-drain comparators (e.g., LMC7221), it requires no external pull-up resistor, simplifying PCB layout and reducing component count. It delivers VOH ≥4.8V and VOL ≤0.2V at 5V/5mA, enabling direct interface with standard CMOS/TTL inputs.
Can the LMC7211AIM5X/NOPB operate from a single 2.7V supply?
Yes, the LMC7211AIM5X/NOPB is fully characterized and functional at 2.7V supply, with specified parameters including 420ns tPLH propagation delay, 5mV max input offset (NAI grade), and rail-to-rail input range extending 200mV below ground. This makes it suitable for applications powered by partially discharged lithium or alkaline cells.
What package type and marking code identify the LMC7211AIM5X/NOPB?
The LMC7211AIM5X/NOPB is supplied in a 5-pin SOT-23 (DBV) package with dimensions 3.05mm × 3.00mm × 1.43mm. Its top-side marking is "C00A", confirmed in TI's Packaging Information Addendum. The "/NOPB" suffix indicates lead-free (RoHS-compliant) finish with NIPDAU/SN plating and MSL Level-1 rating.
