Product details
Overview
LMV7275MG/NOPB from Texas Instruments is a single-channel, rail-to-rail input, low-power comparator with open-drain output, designed for 1.8-V to 5.5-V operation. It delivers 9 µA supply current per channel, 4 mV max input offset voltage, and 880 ns propagation delay (20-mV overdrive at 1.8 V), enabling precise voltage monitoring in ultra-low-power battery systems.
For engineers reviewing the LMV7275MG/NOPB datasheet, LMV7275MG/NOPB pinout, LMV7275MG/NOPB application, or LMV7275MG/NOPB equivalent, key selection criteria include open-drain level-shifting capability up to 5.5 V, −0.1 V to V+ + 0.1 V input common-mode range, and guaranteed operation from −40°C to +85°C in space-constrained SC70-5 packaging.
Technical Context
The LMV7275MG/NOPB uses a BiCMOS process with paralleled PNP/NPN input stages to achieve rail-to-rail input operation extending 0.1 V beyond both supply rails. Its bipolar input stage ensures low noise and stable 10 nA input bias current across temperature.
Unlike the push-pull-output LMV7271/LMV7272, the LMV7275MG/NOPB omits the internal PMOS pull-up device, resulting in an open-drain output that requires an external pull-up resistor - enabling wired-OR logic, I²C-compatible bus interfacing, and level translation between disparate supply domains (e.g., 1.8-V core logic driving a 3.3-V or 5-V interface rail).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct connection to Li-ion, coin-cell, and multi-rail embedded systems without LDO pre-regulation. |
| Supply Current (TYP) | 9 µA at 1.8 V - enables >10-year battery life in always-on sensor wake-up circuits with periodic threshold detection. |
| Input Offset Voltage (MAX) | 4 mV - ensures reliable 10-mV-level signal discrimination in precision battery voltage monitors and low-voltage brownout detectors. |
| Propagation Delay (TYP) | 880 ns at 20-mV overdrive, 1.8 V - provides sub-microsecond response for fast fault detection in power sequencing and overvoltage lockout. |
| Input Common-Mode Range | −0.1 V to V+ + 0.1 V - allows direct sensing of signals at ground or above VCC, critical for supply rail monitoring and zero-crossing detection. |
| Output Leakage (TYP) | 2 pA at VO = 5 V - minimizes pull-up current error in high-impedance level-shifted interfaces, preserving accuracy in µA-range bias networks. |
| ESD Rating (HBM) | ±2000 V - meets IEC 61000-4-2 Level 2 requirements for handheld and wearable end-equipment handling robustness. |
Pinout & Package
LMV7275MG/NOPB is housed in a 5-pin SC70 package (1.25 mm × 2.00 mm), optimized for high-density portable PCB layouts. The package supports reflow soldering per JEDEC J-STD-020 and features moisture sensitivity level 1 (MSL 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | Noninverting Input | High-impedance analog input accepting signals from −0.1 V to V+ + 0.1 V; connects to sensed node in threshold-detection circuits. |
| GND | Negative Supply | Reference return path for supply and input signals; must be low-impedance and decoupled near device. |
| −IN | Inverting Input | Differential input terminal; used with +IN to configure window, zero-crossing, or reference-comparison topologies. |
| VOUT | Open-Drain Output | Active-low output requiring external pull-up; enables bidirectional bus sharing, level shifting, and OR'ed interrupt lines. |
| V+ | Positive Supply | Primary power rail (1.8–5.5 V); supplies internal bias and output stage; bypass with 0.1 µF ceramic capacitor. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7211IDBVR | Push-pull output, 11 µA supply current, 1.5-V min supply, 150-ns propagation delay | Lacks open-drain flexibility; unsuitable for wired-OR or level-shifting; better for high-speed digital interfacing | Select TLV7211IDBVR only when fast edge rates and minimal external components outweigh need for bus sharing. |
| MAX9021AUT+T | Open-drain output, 1 µA supply current, 1.6-V min supply, but 5.5-µs propagation delay and ±15-mV offset | Optimized for nano-power wake-up, not precision thresholding; slower response limits use in real-time fault detection | Choose MAX9021AUT+T for multi-year battery life where speed is secondary to ultra-low IQ; avoid for <1-ms response requirements. |
Compared with TLV7211IDBVR and MAX9021AUT+T, LMV7275MG/NOPB uniquely balances open-drain versatility, sub-1-µs speed, and microamp-level IQ - making it the optimal choice for space-constrained, multi-rail systems requiring both precision and interface flexibility.

FAQ
What is the maximum allowable output pull-up voltage for LMV7275MG/NOPB?
The LMV7275MG/NOPB open-drain output supports external pull-up voltages up to 5.5 V, independent of its own supply voltage (1.8 V to 5.5 V). This enables level-shifting between disparate voltage domains - for example, a 1.8-V-powered LMV7275MG/NOPB can drive a 3.3-V or 5-V logic bus. Exceeding 5.5 V risks damage to the output transistor's drain junction.
Does LMV7275MG/NOPB require hysteresis for stable operation with slow-moving input signals?
Yes - LMV7275MG/NOPB has high gain (>100 dB) and can oscillate when input differential voltage is near zero and subject to noise or slow slew rates. Hysteresis (via positive feedback) is recommended for non-inverting configurations or zero-crossing detection. Typical hysteresis bands of 5–50 mV suppress chatter while maintaining accurate threshold detection in LMV7275MG/NOPB applications.
Can LMV7275MG/NOPB operate from a single 1.8-V supply while sensing signals below ground?
No - LMV7275MG/NOPB supports an input common-mode range from −0.1 V to V+ + 0.1 V. With V+ = 1.8 V and V− = GND (0 V), the lowest valid input is −0.1 V. Inputs below −0.1 V violate absolute maximum ratings and may cause latch-up or parametric shift. For true sub-ground sensing, a negative supply or level-shifting front-end is required.
What is the typical output leakage current of LMV7275MG/NOPB when VOUT is pulled to 5 V?
The typical output leakage current of LMV7275MG/NOPB is 2 pA when VOUT = 5 V, as specified in the 5-V Electrical Characteristics table. This ultra-low leakage ensures minimal error in high-impedance pull-up networks (e.g., 10 MΩ), preserving accuracy in precision level-shifting and battery-monitoring circuits using LMV7275MG/NOPB.
Is LMV7275MG/NOPB pin-compatible with LMV7271MG/NOPB?
Yes - LMV7275MG/NOPB and LMV7271MG/NOPB share identical SC70-5 pinout (pin 1: +IN, pin 2: GND, pin 3: −IN, pin 4: VOUT, pin 5: V+), same footprint, and identical thermal characteristics. The sole functional difference is output topology: LMV7271MG/NOPB has push-pull output, while LMV7275MG/NOPB has open-drain. Board reuse is possible with minor schematic changes to the output network.
