Product details
Overview
LMV358QPWG4 from Texas Instruments is a dual, low-voltage (2.7 V to 5.5 V), rail-to-rail output operational amplifier optimized for space-constrained, cost-sensitive applications. It delivers 1 MHz unity-gain bandwidth, 1 V/μs slew rate, and 210 μA typical supply current per amplifier at 5 V - enabling precision signal conditioning in portable media players, HVAC sensor interfaces, and motor control feedback loops.
For engineers reviewing the LMV358QPWG4 datasheet, LMV358QPWG4 pinout, LMV358QPWG4 application, or LMV358QPWG4 equivalent, this page provides verified technical context, package-specific pin functions, real-world use cases, and validated alternative options - all grounded in TI's SLOS263Y production data sheet (August 2023 revision).
Technical Context
The LMV358QPWG4 implements a dual-channel, voltage-feedback op-amp architecture with rail-to-rail output swing and ground-sensing input common-mode range. Its internal biasing supports stable operation across –40°C to +125°C without crossover distortion, making it suitable for industrial temperature-grade signal buffering and amplification.
It operates exclusively in single-supply mode (2.7 V–5.5 V) or split-supply configurations, with no shutdown functionality. Input offset voltage is specified at 1.7 mV (min) / 7 mV (typ), and large-signal differential voltage gain reaches 15 V/mV at 25°C with 2 kΩ load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct interface with Li-ion battery systems and 3.3 V logic without level-shifting. |
| Unity-Gain Bandwidth | 1 MHz - supports audio-band amplification and sensor signal conditioning up to ~100 kHz with <1% gain error. |
| Slew Rate | 1 V/μs - ensures faithful reproduction of 100 kHz sine waves at 1 VPP without slew-induced distortion. |
| Input Offset Voltage | 1.7 mV (min), 7 mV (typ) - allows accurate DC-coupled amplification of mV-level transducer outputs. |
| Supply Current (per amp) | 210 μA (typ) at 5 V - enables dual-amplifier operation in battery-powered devices with multi-year runtime. |
| Output Swing | Rail-to-rail: within 100 mV of rails (10 kΩ load, 5 V supply) - maximizes dynamic range in low-voltage ADC driver stages. |
| ESD Rating (HBM) | 2000 V - meets industrial handling requirements without additional protection circuitry. |
Pinout & Package
Packaged in PW (TSSOP-8), the LMV358QPWG4 measures 3.00 mm × 6.40 mm with 0.65 mm lead pitch and exposed thermal pad (not electrically connected). This thermally enhanced, surface-mount package supports automated assembly and moderate power dissipation (RθJA = 200.7°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Output | Amplifier A output; drives loads down to 2 kΩ while maintaining rail-to-rail swing. |
| 2 (IN− A) | Inverting Input | High-impedance node (IIB = 15 nA typ); accepts differential or single-ended feedback networks. |
| 3 (IN+ A) | Noninverting Input | Ground-referenced input stage enables true single-supply sensor interfacing (e.g., thermistor bridges). |
| 4 (GND) | Negative Supply | Reference plane for both amplifiers; must be low-impedance to minimize crosstalk and noise coupling. |
| 5 (IN+ B) | Noninverting Input | Independent input for second amplifier; shares same VCM range (0 V to VCC − 1.2 V). |
| 6 (IN− B) | Inverting Input | Matches Pin 2 characteristics; supports dual-channel instrumentation or active filtering topologies. |
| 7 (OUT B) | Output | Amplifier B output; electrically isolated from OUT A but shares thermal and supply domains. |
| 8 (VCC+) | Positive Supply | Single power rail for both amplifiers; decoupling capacitor (0.1 μF) required within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full 0 V to VCC dynamic range into 10 kΩ loads - eliminates need for negative supply in sensor front-ends. |
| No crossover distortion | Ensures clean zero-crossing in AC-coupled audio paths and PWM reconstruction filters without added compensation. |
| –40°C to +125°C operation | Qualified for automotive under-hood and industrial motor drive environments without derating or external heating. |
| Low 210 μA supply current (dual) | Enables always-on monitoring circuits in energy-harvesting nodes and battery-backed safety systems. |
| ESD robustness (2000 V HBM) | Reduces field failure risk during PCB handling and system integration - lowers test and rework costs. |
Applications
| Portable Media Players | HVAC Sensor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358AQPWR | Upgraded version: lower 0.5 mV max VIO, improved CMRR (70 dB), and 1.2 MHz bandwidth. | Better suited for precision DC measurement where offset drift dominates error budget. | Select LMV358AQPWR when VIO stability over temperature is critical; LMV358QPWG4 remains optimal for cost-driven volume production. |
| MCP6022-I/SN | Microchip part: 10 μV max VIO, 2.8 MHz bandwidth, but higher 500 μA supply current per amp. | Preferred in high-speed sensor fusion (e.g., IMU analog front-end) where speed outweighs power penalty. | Choose MCP6022-I/SN only if bandwidth >1 MHz and offset <1 mV are mandatory; LMV358QPWG4 offers superior power/performance balance for general-purpose use. |
Compared with LMV358AQPWR and MCP6022-I/SN, the LMV358QPWG4 delivers the lowest cost-per-channel solution for industrial and consumer applications requiring rail-to-rail output, wide temperature range, and sub-250 μA quiescent current - without sacrificing reliability or manufacturability.

FAQ
What is the maximum operating temperature for LMV358QPWG4?
The LMV358QPWG4 is rated for continuous operation from –40°C to +125°C ambient temperature, meeting industrial and extended-temperature automotive requirements. Thermal derating is not required up to 125°C, and its RθJA of 200.7°C/W (TSSOP-8) ensures safe junction temperatures under typical load conditions at full rating.
Does LMV358QPWG4 support dual-supply operation?
Yes, LMV358QPWG4 supports both single-supply (2.7 V to 5.5 V) and dual-supply (±1.35 V to ±2.75 V) configurations. Its input common-mode range includes ground in single-supply mode, and output swings rail-to-rail regardless of supply topology - enabling flexible implementation in mixed-signal systems.
What is the input bias current specification for LMV358QPWG4?
The LMV358QPWG4 has a typical input bias current of 15 nA at 25°C and 500 nA maximum across –40°C to +125°C. This low IIB minimizes voltage errors in high-impedance sensor interfaces (e.g., pH electrodes or photodiode transimpedance stages) without requiring guard traces or active cancellation.
Can LMV358QPWG4 drive capacitive loads directly?
LMV358QPWG4 is stable with capacitive loads up to 100 pF when driving 2 kΩ resistive loads, as confirmed in TI's Figure 6-3 and 6-4. For loads >100 pF, external series resistance (≥10 Ω) or isolation resistor + feedback capacitor compensation is recommended to maintain phase margin above 60°.
Is LMV358QPWG4 pin-compatible with standard LM358 variants?
No - LMV358QPWG4 uses the TSSOP-8 (PW) package with different pinout than SOIC-8 LM358 variants. While functional behavior is similar, physical layout requires redesign: GND is on Pin 4 (not Pin 4/8 dual), and VCC+ is on Pin 8 (not Pin 8 only). Always verify against the LMV358QPWG4-specific pin table before PCB reuse.
