Product details
Overview
LMV358Q1MM/NOPB from Texas Instruments is a dual, rail-to-rail output operational amplifier designed for low-voltage (2.7 V to 5.5 V), single-supply industrial and automotive applications. It delivers 1 MHz gain-bandwidth product, 1 V/µs slew rate, 210 µA supply current per amplifier, −40°C to +125°C operating temperature, and rail-to-rail output swing (V+ −10 mV / V− +65 mV at 10 kΩ).
For engineers reviewing the LMV358Q1MM/NOPB datasheet, LMV358Q1MM/NOPB pinout, LMV358Q1MM/NOPB application, or LMV358Q1MM/NOPB equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, input common-mode range extending to ground (−0.2 V), no crossover distortion, and verified 2.7-V/5-V DC/AC performance across temperature.
Technical Context
The LMV358Q1MM/NOPB implements a bipolar-input, bipolar-output stage architecture optimized for noise performance and output drive capability in low-voltage operation. Its rail-to-rail output stage enables full dynamic range utilization near supply rails, while the input common-mode voltage range includes ground-critical for single-supply sensor interfacing and signal conditioning.
It operates reliably across 2.7 V to 5.5 V supply and −40°C to +125°C ambient, with guaranteed 1 MHz GBWP and 1 V/µs slew rate under 5 V conditions. Input offset voltage is specified at 1.7–7 mV (typ), with 5 µV/°C drift, and CMRR ≥50 dB over 0 V ≤ VCM ≤ 4 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports battery-powered and 3.3 V/5 V system rails without level shifting |
| Gain-Bandwidth Product | 1 MHz - enables stable unity-gain buffer and low-frequency active filter designs up to ~100 kHz |
| Slew Rate | 1 V/µs - sufficient for 100 kHz full-scale sine output at 1 Vpp without distortion |
| Supply Current (per amp) | 210 µA - enables dual-channel amplification in space-constrained, low-power portable systems |
| Rail-to-Rail Output Swing | V+ −10 mV / V− +65 mV @ 10 kΩ - maximizes signal headroom in 3.3 V systems (e.g., 0–3.29 V output range) |
| Input Common-Mode Range | −0.2 V to V+ − 0.8 V - allows direct sensing of signals referenced to ground in single-supply configurations |
| AEC-Q100 Grade | Grade 1 (−40°C to +125°C) - qualified for under-hood automotive electronics and industrial control environments |
Pinout & Package
LMV358Q1MM/NOPB is packaged in an 8-pin VSSOP (DGK) with nominal body size 3.00 mm × 3.00 mm, optimized for high-density PCB layouts and thermal performance (RθJA = 235°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load directly; rail-to-rail capable |
| 2 | IN− A | Inverting input for channel A - accepts feedback network for closed-loop gain configuration |
| 3 | IN+ A | Noninverting input for channel A - connects to sensor or reference signal; includes ground in common-mode range |
| 4 | V− | Negative supply terminal - tied to GND in single-supply operation; must be decoupled locally |
| 5 | IN+ B | Noninverting input for channel B - independent signal path; identical electrical specs to channel A |
| 6 | IN− B | Inverting input for channel B - supports separate feedback loop for second amplifier stage |
| 7 | OUT B | Amplifier B output - fully independent output; no crosstalk impact on channel A per typical characteristics |
| 8 | V+ | Positive supply terminal - accepts 2.7–5.5 V; requires local 0.1 µF ceramic decoupling to GND |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358M/NOPB | Commercial-grade (−40°C to +125°C), same electrical specs, SOIC-8 package (4.90 mm × 3.91 mm) | Lacks AEC-Q100 qualification; not approved for automotive safety-critical subsystems | Select when automotive qualification is unnecessary and board space permits larger SOIC footprint |
| MCP6022-E/SN | Higher GBWP (10 MHz), higher supply current (250 µA), wider VCM (to V+), but no AEC-Q100 Grade 1 rating | Better for higher-speed signal chains (e.g., ultrasonic sensing); unsuitable for automotive under-hood use | Choose only if bandwidth >1 MHz is required and automotive qualification is not mandated |
Compared with LMV358M/NOPB and MCP6022-E/SN, LMV358Q1MM/NOPB uniquely combines AEC-Q100 Grade 1 qualification, VSSOP space efficiency, and proven 1 MHz performance at 210 µA - making it the optimal choice for compact, automotive-grade dual op-amp functions where reliability and footprint are co-prioritized.

FAQ
What is the maximum capacitive load the LMV358Q1MM/NOPB can drive stably in unity-gain configuration?
The LMV358Q1MM/NOPB is characterized for stable unity-gain operation with up to 200 pF capacitive load, as verified in the datasheet's Figure 7-23 (Gain and Phase vs Capacitive Load). Driving heavier loads requires isolation resistors (e.g., 620 Ω) or compensation networks per Figure 8-3 to maintain phase margin above 60° and prevent oscillation.
Does the LMV358Q1MM/NOPB support true single-supply operation with input signals at ground potential?
Yes. The LMV358Q1MM/NOPB features an input common-mode voltage range extending to −0.2 V (below ground) and up to V+ − 0.8 V, enabling direct interface with ground-referenced sources like thermistors, current shunts, and bridge sensors - a key advantage over older op-amps that require input biasing above ground.
What is the guaranteed input offset voltage specification for LMV358Q1MM/NOPB over temperature?
The LMV358Q1MM/NOPB has a maximum input offset voltage of 9 mV over the full −40°C to +125°C operating range, per Section 7.9 (5-V DC Electrical Characteristics). At 25°C and 5 V supply, the typical value is 7 mV with a maximum of 7 mV - ensuring predictable DC accuracy in precision sensor interfaces.
Is LMV358Q1MM/NOPB pin-compatible with standard LM358 packages?
No. LMV358Q1MM/NOPB uses the 8-pin VSSOP (DGK) package (3.00 mm × 3.00 mm), whereas standard LM358 variants commonly use SOIC-8 (4.90 mm × 3.91 mm) or PDIP-8. Pin functions are identical (dual op-amp topology), but PCB layout and thermal design must accommodate the smaller VSSOP footprint and different pad geometry.
How does the LMV358Q1MM/NOPB eliminate crossover distortion compared to LM358?
The LMV358Q1MM/NOPB uses an improved bipolar output stage architecture that eliminates the dead zone around zero crossing - a known limitation of the LM358's class-AB output. This is confirmed by side-by-side scope waveforms in Figure 8-1 (LMV324) vs Figure 8-2 (LM324) in the datasheet, showing clean zero-crossing behavior in voltage-follower configurations.
