Product details
Overview
LMV612MMX/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, ±200-mV beyond-rail input common-mode range, and 30-mV output swing from rail with 2-kΩ load - enabling precision signal conditioning in space-constrained battery-powered systems such as portable audio pre-amplifiers and supply current monitors.
For engineers reviewing the LMV612MMX/NOPB datasheet, LMV612MMX/NOPB pinout, LMV612MMX/NOPB application, or LMV612MMX/NOPB equivalent, key selection criteria include its guaranteed 1.8-V operation, −40°C to +125°C temperature range, low input offset voltage (max 5.5 mV), high CMRR (min 55 dB over extended VCM), and VSSOP-8 package compatibility with area-sensitive PCB layouts.
Technical Context
The LMV612MMX/NOPB integrates two independent amplifiers sharing a common 1.8-V–5.5-V supply, each featuring complementary-input differential pairs enabling rail-to-rail input operation down to V− − 0.2 V and up to V+ + 0.2 V at 25°C. Its unity-gain-stable architecture supports closed-loop gains ≥1 with 67° phase margin and 7 dB gain margin at 1.8 V.
Each channel achieves 0.35 V/µs slew rate and 60–86 dB CMRR depending on common-mode voltage and supply, while maintaining <0.023% THD at 1 kHz into 600 Ω - confirming suitability for low-distortion analog front-ends in consumer computing and battery monitoring circuits where supply headroom is limited.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - enables direct integration into Li-ion single-cell (3.0–4.2 V) and coin-cell (1.8–3.0 V) powered systems without level-shifting. |
| Gain-Bandwidth Product | 1.4 MHz - supports stable unity-gain buffer and gain-of-10 configurations up to ~140 kHz for sensor signal amplification. |
| Quiescent Current per Channel | 103 µA typical - allows dual-channel operation under 210 µA total, critical for multi-day battery life in portable equipment. |
| Input Offset Voltage | Max 5.5 mV - ensures ≤0.55% error in 1-V full-scale measurements without trimming, suitable for supply current sensing with 2-kΩ RSENSE. |
| Output Swing (2-kΩ load) | Within 30 mV of rails at 1.8 V - preserves >96% dynamic range in low-voltage ADC driver applications. |
| Input Common-Mode Range | V− − 0.2 V to V+ + 0.2 V - permits direct interface to transducers operating below ground or above supply, e.g., shunt-based current monitors. |
| Operating Temperature | −40°C to +125°C - qualified for industrial-grade embedded control and automotive cabin electronics mounting near heat sources. |
Pinout & Package
The LMV612MMX/NOPB is packaged in an 8-pin VSSOP (DGK) with 3.00 mm × 3.00 mm body size and 0.65-mm lead pitch, optimized for automated assembly and thermal performance (RθJA = 184.5°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 8 mA sourcing / 9 mA sinking at 1.8 V; rail-to-rail swing enables full utilization of 12-bit ADC input range. |
| 2 | −IN A | Inverting input A - high-impedance node (15 nA bias current) for precision feedback networks in transimpedance or difference amplifier configurations. |
| 3 | +IN A | Noninverting input A - accepts signals from V− − 0.2 V to V+ + 0.2 V, supporting ground-referenced sensors in single-supply systems. |
| 4 | V− | Negative supply - connects to system ground in single-supply mode; must be decoupled with 0.1-µF ceramic capacitor within 5 mm. |
| 5 | +IN B | Noninverting input B - electrically isolated from Channel A; enables dual-path signal processing (e.g., simultaneous voltage and current monitoring). |
| 6 | −IN B | Inverting input B - shares same input stage topology as Pin 2; supports matched gain settings across both channels with minimal inter-channel drift. |
| 7 | OUT B | Amplifier B output - identical AC/DC performance to OUT A; amp-to-amp isolation >123 dB prevents crosstalk in stereo audio or dual-sensor interfaces. |
| 8 | V+ | Positive supply - accepts 1.8–5.5 V; PSRR >100 dB suppresses ripple from noisy DC-DC converters feeding mixed-signal subsystems. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal acquisition from 0 V to V+ without external level-shifting circuitry, reducing BOM count in portable medical sensors. |
| 100-µA per-channel quiescent current | Permits continuous dual-channel monitoring in always-on battery applications (e.g., wearable health trackers) with sub-1-µA sleep-mode leakage. |
| Guaranteed 1.8-V operation | Supports direct connection to ultra-low-voltage microcontrollers (e.g., MSP430FRxx) and energy-harvesting PMUs without voltage boosting. |
| −40°C to +125°C temperature range | Validates functionality in automotive engine-control modules and industrial motor drives where ambient temperatures exceed 105°C. |
| Low input offset drift (5.5 µV/°C) | Minimizes calibration frequency in precision thermistor or RTD measurement bridges exposed to wide ambient swings. |

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 |
|---|---|---|---|
| MCP6022-E/SN | Higher supply current (125 µA/channel), wider GBW (10 MHz), no guaranteed 1.8-V operation - requires ≥2.7-V minimum supply. | Better suited for higher-speed active filters but incompatible with 1.8-V microcontroller I/O domains without level shifters. | Select MCP6022-E/SN only when bandwidth >1 MHz is required and supply ≥2.7 V is available; LMV612MMX/NOPB remains optimal for true 1.8-V systems. |
| TLV2462IDR | Lower quiescent current (23 µA/channel), lower GBW (6.4 MHz), rail-to-rail output only (not input); VOS max = 3.5 mV. | Superior battery life in ultra-low-power wake-on-event sensors, but input cannot accept signals below V− - limiting shunt monitor flexibility. | Choose TLV2462IDR for longest battery life where input common-mode range is constrained to V− to V+, otherwise LMV612MMX/NOPB provides broader signal handling. |
Compared with MCP6022-E/SN and TLV2462IDR, the LMV612MMX/NOPB uniquely balances guaranteed 1.8-V operation, rail-to-rail input/output, and 1.4-MHz bandwidth - making it the only dual op-amp in this group fully compatible with modern ultra-low-voltage SoCs while maintaining sufficient speed for precision analog sensing.

FAQ
What is the minimum supply voltage supported by the LMV612MMX/NOPB?
The LMV612MMX/NOPB is fully specified and guaranteed to operate down to 1.8 V, with electrical characteristics validated at 1.8 V, 2.7 V, and 5 V. This makes it suitable for direct integration with 1.8-V logic families and single-cell Li-ion or alkaline battery systems without voltage regulation overhead. Operation below 1.8 V is not characterized or recommended.
Does the LMV612MMX/NOPB support rail-to-rail input operation?
Yes, the LMV612MMX/NOPB supports rail-to-rail input operation with a common-mode voltage range extending 200 mV beyond both supply rails (V− − 0.2 V to V+ + 0.2 V at 25°C). This enables direct interfacing with transducers and sensors whose outputs fall outside the supply domain - a key advantage over amplifiers with restricted input ranges.
What is the maximum output current capability of the LMV612MMX/NOPB?
At 1.8 V supply, the LMV612MMX/NOPB can source up to 8 mA and sink up to 9 mA while maintaining specified output swing and linearity. At 5 V, sourcing increases to 100 mA and sinking to 65 mA. These values are measured under short-circuit conditions and define safe continuous drive limits into moderate-impedance loads like RC filters or ADC input networks.
Is the LMV612MMX/NOPB suitable for automotive applications?
Yes, the LMV612MMX/NOPB is qualified for operation from −40°C to +125°C and meets AEC-Q100 stress test requirements for temperature cycling and HBM ESD (±2000 V). Its guaranteed 1.8-V performance and rail-to-rail input make it appropriate for cabin electronics, battery management subsystems, and ADAS sensor interfaces where extended temperature and low-voltage resilience are mandatory.
How does the LMV612MMX/NOPB compare to the single-channel LMV611 in terms of footprint and thermal performance?
The LMV612MMX/NOPB uses an 8-pin VSSOP package (3.0 mm × 3.0 mm), whereas the LMV611 occupies a 5-pin SC70 (2.0 mm × 1.25 mm). While the LMV611 offers smaller area, the LMV612MMX/NOPB provides dual-channel functionality in only 2.25× the silicon area - with superior thermal resistance (RθJA = 184.5°C/W vs. 285.9°C/W for SC70), enabling higher sustained output current in compact layouts.
