Product details
Overview
LMV612MA/NOPB from Texas Instruments is a dual, rail-to-rail input/output, low-power operational amplifier optimized for 1.8-V to 5.5-V single-supply operation. It delivers 1.4-MHz gain-bandwidth, 100-µA per-channel quiescent current, 4-mV max input offset voltage, and output swing within 30 mV of rails under 2-kΩ load - enabling precision signal conditioning in battery-powered audio pre-amplifiers and supply current monitoring circuits.
For engineers reviewing the LMV612MA/NOPB datasheet, LMV612MA/NOPB pinout, LMV612MA/NOPB application, or LMV612MA/NOPB equivalent, key selection criteria include its guaranteed 1.8-V operation, −40°C to +125°C industrial-plus temperature range, rail-to-rail I/O capability, low-noise (60 nV/√Hz at 10 kHz), and VSSOP-8 package compatibility with space-constrained portable designs.
Technical Context
The LMV612MA/NOPB integrates two independent high-precision op-amps in a single die, each featuring complementary-input-stage architecture enabling rail-to-rail input common-mode range extending 200 mV beyond supplies and rail-to-rail output swing. Its 1.4-MHz unity-gain bandwidth and 0.35 V/µs slew rate support stable unity-gain buffer and low-frequency instrumentation configurations.
Designed for ultra-low-power systems, it draws only 103 µA per channel at 1.8 V while maintaining 75 dB minimum CMRR over 0–0.6 V and 1.4–1.8 V common-mode ranges. Input bias current remains below 15 nA, and input offset drift is limited to 5.5 µV/°C - critical for DC-coupled sensor interfaces and battery voltage monitoring.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV6002IDR | Higher 1.5-MHz GBW but 150-µA IQ; 3-mV max VOS; same VSSOP-8 package. | Better bandwidth for faster settling in data-acquisition systems; higher supply current reduces battery life. | Choose TLV6002IDR when >1.4-MHz bandwidth is required and 50-µA extra per-channel IQ is acceptable. |
| OPA2313AIDR | Lower 1.2-mV max VOS and 50-µA IQ, but 1-MHz GBW; same VSSOP-8 footprint. | Superior DC precision for high-resolution current sensing; reduced bandwidth limits AC signal fidelity. | Choose OPA2313AIDR for sub-0.1% accuracy requirements where bandwidth <1 MHz suffices. |
Compared with TLV6002IDR and OPA2313AIDR, LMV612MA/NOPB offers the optimal balance of ultra-low power (103 µA), adequate bandwidth (1.4 MHz), and robust rail-to-rail performance across 1.8–5.5 V - making it ideal for cost-sensitive, battery-constrained general-purpose analog signal conditioning.

FAQ
What supply voltage range does the LMV612MA/NOPB support?
The LMV612MA/NOPB operates from 1.8 V to 5.5 V, with full specifications guaranteed at 1.8 V, 2.7 V, and 5 V. This enables direct integration into Li-ion-powered devices, coin-cell systems, and mixed-voltage industrial controllers without external regulators or level shifters. Its ability to function reliably at 1.8 V makes LMV612MA/NOPB especially suited for ultra-low-power sensor nodes and energy-harvesting applications.
Does the LMV612MA/NOPB feature rail-to-rail input and output capability?
Yes, the LMV612MA/NOPB provides true rail-to-rail input and output operation. Its input common-mode voltage extends 200 mV beyond both supply rails (V− − 0.2 V to V+ + 0.2 V), and its output swings within 30 mV of the rails under 2-kΩ load at 1.8 V. This capability allows LMV612MA/NOPB to maximize dynamic range in single-supply systems such as battery voltage monitors and audio pre-amplifiers.
What is the maximum input offset voltage specified for the LMV612MA/NOPB?
The LMV612MA/NOPB has a maximum input offset voltage of 4 mV across temperature and process variations. This specification applies to both channels and is ensured over the full −40°C to +125°C operating range. For precision applications like current sensing or thermistor amplification, this 4-mV limit translates to predictable, bounded DC error - and LMV612MA/NOPB's 5.5 µV/°C TCVOS ensures minimal drift over temperature excursions.
How much quiescent current does the LMV612MA/NOPB draw per channel?
The LMV612MA/NOPB draws 103 µA per channel typical at 1.8 V and 25°C, with a maximum of 185 µA over temperature and process. This ultra-low quiescent current enables multi-year battery life in always-on monitoring circuits. When both channels are active, total supply current remains under 200 µA - significantly lower than most competing rail-to-rail op-amps, making LMV612MA/NOPB ideal for wearable and IoT edge sensors.
Which package options are available for the LMV612MA/NOPB?
The LMV612MA/NOPB is offered exclusively in the 8-pin VSSOP (DGK) package, measuring 3.00 mm × 3.00 mm with 0.65-mm lead pitch. This compact, thermally efficient surface-mount package supports high-density PCB layouts and automated assembly. While the broader LMV61x family includes SOIC-8 variants, the LMV612MA/NOPB part number specifically denotes the VSSOP-8 version - confirmed by TI's official orderable addendum and packaging documentation.
