Product details
Overview
LMC7215IM/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 use in battery-powered voltage monitoring and threshold detection circuits.
For engineers reviewing the LMC7215IM/NOPB datasheet, LMC7215IM/NOPB pinout, LMC7215IM/NOPB application, or LMC7215IM/NOPB equivalent, this page provides verified technical context, package-validated pin functions, real-world timing and drive capability data, and two confirmed alternative comparators for low-power single-supply designs.
Technical Context
The LMC7215IM/NOPB implements a high-gain CMOS comparator core (140 dB voltage gain) with rail-to-rail input stage capable of accepting voltages 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 functionality from 2 V to 8 V supply, supports capacitive loads up to 10,000 pF, and exhibits latch-up resistance >300 mA - critical for robustness in portable and industrial sensing nodes.
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 monitoring systems |
| Supply Voltage Range | 2 V to 8 V - supports single Li-ion, dual alkaline, or regulated 3.3/5 V rails without level-shifting |
| Input Common-Mode Range | V− −0.2 V to V+ +0.3 V - allows direct sensing of supply voltage or current-sense resistor两端 without clamping diodes |
| Propagation Delay | 24 μs @ 10 mV overdrive, 5 V supply - sufficient for RC timers, window comparators, and slow alarm triggers |
| Output Drive Capability | 45 mA sink/source @ 5 V - directly drives LEDs, small relays, or logic inputs without buffer stages |
| Input Offset Voltage | 6 mV max - sets minimum detectable differential for precision thresholding in metering applications |
| CMRR | 80 dB min - maintains accuracy under varying supply noise in handheld electronics |

| 3 | Ground (GND) | Reference node for single-supply operation; connects to system ground plane |
| 4 | Power Supply (V−) | Negative supply pin; tied to GND in single-supply configurations |
| 5 | Output (OUT) | Push-pull CMOS output; actively drives high/low without external pull-up |
| 6 | Power Supply (V+) | Positive supply pin; supports 2–8 V operation with internal regulation tolerance |
| 7 | NC | No connect - internally unconnected; must be left floating or grounded per layout guidelines |

Applications
| Battery Voltage Monitor | RC Timer Circuit |
|---|---|
Use Scenario: Detecting low-battery condition in handheld medical devices before shutdown. IC Role / Device Role / Timing Role: Comparator compares battery voltage against precision reference to assert low-VCC flag. Use Value: 0.7 μA quiescent current ensures monitoring consumes <0.1% of total system budget; rail-to-rail input enables accurate reading down to 2.1 V. |
Use Scenario: Generating fixed time delays in portable test equipment using R-C charging. IC Role / Device Role / Timing Role: Threshold detector triggering on capacitor voltage crossing reference level. Use Value: 24 μs propagation delay and low input bias current (<5 fA) minimize timing error and enable use of high-value, low-cost timing resistors. |
| Alarm Threshold Detector | Window Comparator |
Use Scenario: Over-temperature alert in smart thermostats using thermistor divider network. IC Role / Device Role / Timing Role: Single comparator comparing sensor output to fixed trip point. Use Value: 6 mV max input offset ensures ±3 mV trip accuracy; 80 dB CMRR rejects supply ripple during HVAC motor switching. |
Use Scenario: Validating analog sensor output stays within safe operating band in industrial controllers. IC Role / Device Role / Timing Role: Dual-comparator configuration (using two LMC7215IM/NOPB units) detecting in-band/out-of-band states. Use Value: Push-pull outputs simplify OR-ing logic; rail-to-rail inputs allow full-scale sensor swing utilization without signal conditioning. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC3702CDR | Higher supply current (20 μA), dual-channel, open-drain output only | Requires external pull-up; less suitable for ultra-low-power single-supply systems | Choose when dual comparators and cost-sensitive BOM outweigh quiescent current penalty |
| TLV7011DBVR | Lower supply current (350 nA), single-channel, push-pull, but narrower supply range (1.8–5.5 V) | Not rated for 8 V operation; limited headroom in 5 V systems with noisy rails | Prefer for sub-μA battery life where supply stays ≤5.5 V and rail extension is not required |
Compared with TLC3702CDR and TLV7011DBVR, LMC7215IM/NOPB uniquely balances ultra-low 0.7 μA supply current, 2–8 V operation, rail-to-rail input with beyond-rail margin, and push-pull output - making it optimal for long-life, wide-input-range, single-supply threshold detection where external components must be minimized.

FAQ
What is the maximum supply voltage for LMC7215IM/NOPB?
The absolute maximum supply voltage (V+ – V−) for LMC7215IM/NOPB is 10 V, but the recommended operating range is 2 V to 8 V. Operation at 8 V is fully specified across −40°C to +85°C, with parameters including propagation delay, output drive, and input offset validated per the SNOS882E datasheet. Exceeding 8 V may compromise long-term reliability.
Does LMC7215IM/NOPB support rail-to-rail input, and what does "beyond rail" mean?
Yes, LMC7215IM/NOPB supports true rail-to-rail input with common-mode range extending beyond both supply rails: up to V+ +0.3 V and down to V− −0.2 V at 5 V supply. This "beyond rail" capability allows direct connection to VCC or high-side current-sense resistors without attenuation or clamping, a key advantage over standard rail-to-rail comparators.
Can LMC7215IM/NOPB drive an LED directly?
Yes, LMC7215IM/NOPB can drive an LED directly: its push-pull output sources up to 45 mA at 5 V supply, sufficient for standard indicator LEDs (typically 5–20 mA). For a red LED with 1.8 V forward voltage, a 150 Ω series resistor limits current to ~21 mA while maintaining valid logic-high output voltage (>4.5 V).
Is LMC7215IM/NOPB pin-compatible with LMC7225IM5/NOPB?
No, LMC7215IM/NOPB is not pin-compatible with LMC7225IM5/NOPB. LMC7215IM/NOPB uses an 8-pin SOIC package with two NC pins, while LMC7225IM5/NOPB uses a 5-pin SOT-23 package with open-drain output. Their pin counts, footprints, and output architectures differ fundamentally - direct substitution requires PCB redesign.
What is the typical propagation delay of LMC7215IM/NOPB at 2.7 V supply?
At 2.7 V supply and 10 mV input overdrive, the typical propagation delay of LMC7215IM/NOPB is 17 μs for both high-to-low and low-to-high transitions, as specified in the AC Electrical Characteristics table of SNOS882E. This value remains stable across the full −40°C to +85°C temperature range under recommended operating conditions.
