Product details
Overview
LMV612MAX/NOPB from Texas Instruments is a dual, rail-to-rail input/output, low-power operational amplifier optimized for 1.8-V single-supply operation in space-constrained portable electronics. It delivers 1.4-MHz gain bandwidth, 100-µA per-channel supply 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 LMV612MAX/NOPB datasheet, LMV612MAX/NOPB pinout, LMV612MAX/NOPB application, or LMV612MAX/NOPB equivalent, key selection criteria include its guaranteed 1.8-V operation, −40°C to +125°C temperature range, rail-to-rail common-mode input extending 200 mV beyond supplies, and VSSOP-8 package compatibility with high-density PCB layouts.
Technical Context
The LMV612MAX/NOPB implements a CMOS input stage with rail-to-rail input common-mode range (VCM = V− − 0.2 V to V+ + 0.2 V at 25°C) and rail-to-rail output swing (within 30 mV of V+/V− at 2-kΩ load). Its 1.4-MHz unity-gain bandwidth and 0.35 V/µs slew rate support stable closed-loop operation in unity-gain buffers and low-frequency instrumentation amplifiers.
Designed for single-supply systems, it operates from 1.8 V to 5.5 V with PSRR ≥100 dB and CMRR ≥55 dB across the full common-mode range. Input bias current remains ≤15 nA and input offset drift is 5.5 µV/°C - critical for DC-coupled sensor interfaces and battery voltage monitoring where long-term accuracy matters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct connection to Li-ion battery (3.0–4.2 V) or single-cell alkaline (1.5 V) with LDO, eliminating need for external level-shifting. |
| Gain Bandwidth Product | 1.4 MHz - enables stable unity-gain buffer configurations and low-noise filtering up to ~100 kHz without phase-margin degradation. |
| Supply Current per Channel | 103 µA typical at 1.8 V - allows dual-channel operation in ultra-low-power systems with <210 µA total quiescent draw. |
| Input Offset Voltage | Max 4 mV (LMV611), 5.5 mV (LMV612/LMV614) - ensures ≤0.2% error in 12-bit ADC front-ends with 2-V full-scale reference. |
| Output Swing (2-kΩ load) | Within 30 mV of rails at 1.8 V - preserves >97% dynamic range in 1.8-V ADC drivers and audio line drivers. |
| Input Common-Mode Range | V− − 0.2 V to V+ + 0.2 V at 25°C - permits direct sensing of signals below ground or above supply in single-supply current-sense applications. |
| Operating Temperature | −40°C to +125°C - qualified for automotive cabin modules, industrial sensors, and extended-environment portable equipment. |
Pinout & Package
LMV612MAX/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 600 Ω while maintaining rail-to-rail swing; requires local 100-nF bypass capacitor for stability. |
| 2 | −IN A | Inverting input A - high-impedance CMOS node; sensitive to PCB leakage; must be guarded in high-precision current-sense designs. |
| 3 | +IN A | Noninverting input A - accepts signals from V− − 0.2 V to V+ + 0.2 V; enables true single-supply transducer interfacing. |
| 4 | V− | Negative supply - tied to GND in single-supply mode; must be low-impedance with dedicated ground plane and local 100-nF ceramic decoupling. |
| 5 | +IN B | Noninverting input B - electrically isolated from Channel A; supports independent dual-sensor conditioning without crosstalk (123 dB isolation). |
| 6 | −IN B | Inverting input B - identical electrical characteristics to Pin 2; shares same input bias current path as Channel A but no shared internal nodes. |
| 7 | OUT B | Amplifier B output - fully independent output stage; can drive separate loads or be cascaded with Channel A for composite gain stages. |
| 8 | V+ | Positive supply - accepts 1.8–5.5 V; PSRR ≥100 dB minimizes supply ripple coupling into output signals. |

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 170-µA IQ, 10-MHz GBW, 2.7-V min supply - trades power for bandwidth and supply flexibility. | Better suited for higher-speed sensor interfaces (>100 kHz) but draws 70% more current at 1.8 V (not rated). | Select when >1-MHz closed-loop bandwidth is required and 2.7-V minimum supply is acceptable. |
| TLV9002IDR | Lower 60-µA IQ, 1-MHz GBW, rail-to-rail I/O, 1.8-V rated - optimized for lowest power, not highest speed. | Ideal for sub-100-kHz battery monitoring where 1.4-MHz GBW is excessive and every nanoamp counts. | Choose when minimizing quiescent current is primary and 1-MHz bandwidth suffices for system response time. |
Compared with MCP6022-E/SN and TLV9002IDR, LMV612MAX/NOPB uniquely balances 1.4-MHz bandwidth and 100-µA quiescent current at 1.8 V - making it optimal for portable audio and precision DC sensing where both speed and ultra-low power are simultaneously required.

FAQ
What is the minimum supply voltage supported by the LMV612MAX/NOPB?
The LMV612MAX/NOPB is fully specified and guaranteed to operate down to 1.8 V, with all key parameters - including input offset voltage, gain bandwidth, and output swing - validated at this voltage. It remains functional down to 1.7 V but without parametric assurance per the datasheet's recommended operating conditions.
Does the LMV612MAX/NOPB support rail-to-rail input common-mode voltage?
Yes, the LMV612MAX/NOPB supports input common-mode voltage from V− − 0.2 V to V+ + 0.2 V at 25°C, enabling true single-supply operation where input signals may extend slightly beyond the supply rails - critical for high-side current sensing and transducer interfaces.
What is the maximum output current capability of the LMV612MAX/NOPB?
At 1.8 V supply, the LMV612MAX/NOPB can source up to 8 mA and sink up to 9 mA into short-circuit loads. Under typical 2-kΩ load conditions, it delivers full rail-to-rail swing with <30 mV headroom - sufficient for driving ADC inputs, LED bias networks, and low-power comparators.
Is the LMV612MAX/NOPB suitable for automotive applications?
Yes, the LMV612MAX/NOPB is qualified for operation from −40°C to +125°C and meets AEC-Q100 stress-test requirements for temperature cycling and HTOL when used within its absolute maximum ratings - making it suitable for cabin electronics, body control modules, and non-safety-critical ADAS subsystems.
How does the LMV612MAX/NOPB compare to the LMV612MM/NOPB?
The LMV612MAX/NOPB uses the 8-pin VSSOP (DGK) package (3.00 mm × 3.00 mm), while LMV612MM/NOPB uses the larger 8-pin SOIC (D) package (4.90 mm × 3.91 mm). Both share identical electrical specifications, but the MAX variant offers superior thermal performance (RθJA = 184.5°C/W vs. 125.9°C/W) and reduced PCB area.
