Product details
Overview
LMC7215IMX/NOPB from Texas Instruments is a micro-power, rail-to-rail CMOS comparator with push-pull output, 0.7 μA typical supply current, 2 V to 8 V supply range, and input common-mode voltage extending beyond both rails. It delivers 45 mA output drive at 5 V and features 25 μs propagation delay (10 mV overdrive), enabling ultra-low-power battery monitoring and threshold detection in portable instrumentation.
For engineers reviewing the LMC7215IMX/NOPB datasheet, LMC7215IMX/NOPB pinout, LMC7215IMX/NOPB application, or LMC7215IMX/NOPB equivalent, this page provides verified technical context, SOIC-8 package mapping, real-world timing and drive capability data, and validated alternative options for low-power comparator selection.
Technical Context
The LMC7215IMX/NOPB implements a high-gain CMOS comparator core (140 dB voltage gain) with rail-to-rail input stage capable of accepting signals up to 0.3 V beyond V+ and V−. Its push-pull output eliminates external pull-up resistors, reducing system power and simplifying interface to logic or discrete loads.
It operates across −40°C to +85°C with guaranteed performance from 2.7 V to 5 V, supports capacitive loads up to 10,000 pF with minimal delay impact, and exhibits latch-up resistance exceeding 300 mA - critical for robust operation in noisy or fault-prone environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 0.7 μA typical - enables multi-year operation on coin-cell batteries in always-on sensing nodes. |
| Supply Voltage Range | 2 V to 8 V - supports single-cell Li-ion (3.0–4.2 V), dual-cell alkaline (2.4–3.2 V), and 5 V rail systems without level-shifting. |
| Input Common-Mode Range | V− − 0.2 V to V+ + 0.3 V - allows direct sensing of supply rails or current-sense resistor voltages without attenuation networks. |
| Propagation Delay | 24 μs @ 10 mV overdrive, 5 V supply - suitable for RC timers, window comparators, and slow-response alarm circuits. |
| Output Drive Capability | 45 mA sink/source @ 5 V - drives LEDs, small relays, or logic inputs directly without buffer stages. |
| Input Offset Voltage | 6 mV max - ensures reliable detection of ≥10 mV thresholds in precision threshold applications. |
| CMRR | 80 dB min - maintains accuracy in presence of supply ripple or ground noise up to 100 mVpp. |
Pinout & Package
LMC7215IMX/NOPB is housed in an 8-pin SOIC (D package), 3.91 mm × 4.90 mm footprint, 1.75 mm max height, RoHS-compliant with Sn finish and Level-1 moisture sensitivity rating.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (−) | Accepts reference or feedback signal; rail-to-rail common-mode range enables direct connection to V+ or V−. |
| 2 | Non-Inverting Input (+) | Accepts sensed signal; identical input structure and voltage range as Pin 1. |
| 3 | Output | Push-pull CMOS output - actively drives high/low; no external pull-up required; 45 mA drive at 5 V. |
| 4 | GND | Power ground reference; must be low-impedance return path for output current and internal bias. |
| 5 | NC | No connect - internally unconnected; leave floating or tie to GND per layout best practice. |
| 6 | V+ | Positive supply pin; accepts 2 V to 8 V; decoupling capacitor (0.1 μF) recommended near pin. |
| 7 | NC | No connect - internally unconnected; leave floating or tie to GND. |
| 8 | NC | No connect - internally unconnected; leave floating or tie to GND. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with beyond-rail range | Accepts inputs from −0.2 V to V+ + 0.3 V - enables direct high-side current sensing without level shifters. |
| Push-pull output stage | Eliminates need for external pull-up resistor - reduces BOM count, board area, and standby power in battery systems. |
| Ultra-low 0.7 μA supply current | Enables >10-year operation on CR2032 (220 mAh) when active <0.1% of time - ideal for IoT wake-on-event sensors. |
| High output current drive (45 mA) | Directly interfaces to LEDs, piezo buzzers, or TTL/CMOS logic without driver transistors - simplifies analog-to-digital interface. |
| Latch-up resistance >300 mA | Withstands transient overcurrent events (e.g., ESD-induced shorting) without functional failure - improves field reliability. |
Applications
| Battery Voltage Monitor | RC Timer Circuit |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMC7225IM5X/NOPB | Open-drain output, same 0.7 μA supply current and rail-to-rail input; requires external pull-up for logic-high assertion. | Used where level shifting to 15 V or wired-OR bus operation is needed; not suitable for direct LED drive. | Select when interfacing to higher-voltage logic or multiple comparators sharing one output line. |
| TLV3701CDR | 0.85 μA supply current, 36 V max supply, push-pull output, but 1.8 V min supply and 12 μs propagation delay at 10 mV overdrive. | Better suited for wide-supply industrial sensors; faster response but higher quiescent current than LMC7215IMX/NOPB. | Choose for systems requiring >8 V operation or sub-20 μs timing, accepting ~20% higher supply current. |
Compared with LMC7225IM5X/NOPB, LMC7215IMX/NOPB eliminates pull-up resistors and reduces board space in single-load drive applications; versus TLV3701CDR, it offers lower power and rail-to-rail input at the cost of slower response and narrower supply range.

FAQ
What is the maximum supply voltage for LMC7215IMX/NOPB?
The absolute maximum supply voltage (V+ − V−) for LMC7215IMX/NOPB is 10 V, but the recommended operating range is 2 V to 8 V. Operation at 8 V is fully characterized and supported across −40°C to +85°C, while 10 V may cause permanent damage per Absolute Maximum Ratings.
Does LMC7215IMX/NOPB support rail-to-rail input operation?
Yes, LMC7215IMX/NOPB supports true rail-to-rail input with common-mode range extending beyond both supply rails: down to V− − 0.2 V and up to V+ + 0.3 V at 5 V supply. This enables direct connection to supply lines or current-sense resistors without attenuation.
Can LMC7215IMX/NOPB drive an LED directly?
Yes, LMC7215IMX/NOPB can drive standard 20 mA LEDs directly: its push-pull output sources/sinks up to 45 mA at 5 V supply. For a red LED (1.8 V VF) with 5 V supply, a 150 Ω series resistor limits current to ~21 mA - well within safe operating limits.
What is the propagation delay of LMC7215IMX/NOPB at 10 mV overdrive?
LMC7215IMX/NOPB has a typical propagation delay of 24 μs for both high-to-low and low-to-high transitions at 10 mV input overdrive and 5 V supply. This value is confirmed in the AC Electrical Characteristics table and applies across the full −40°C to +85°C temperature range.
Is LMC7215IMX/NOPB pin-compatible with other comparators in the LMC72xx family?
No - LMC7215IMX/NOPB (SOIC-8) is not pin-compatible with LMC7215IM5X/NOPB (SOT-23-5) or LMC7225 variants. The SOIC-8 package has dedicated NC pins (5, 7, 8), while SOT-23-5 uses all five pins functionally. Board redesign is required when switching between packages.
