Product details
Overview
LMV358QPWRG4Q1 from Texas Instruments is an automotive-grade dual rail-to-rail output operational amplifier optimized for 2.7-V to 5.5-V single-supply operation. It delivers 1-MHz unity-gain bandwidth, 1-V/µs slew rate, 210-µA typical supply current per amplifier, rail-to-rail output swing (within 10 mV of rails at 10-kΩ load), and operates across −40°C to 125°C. It serves as a low-power signal conditioning front-end in automotive sensor interfaces and body control modules.
For engineers reviewing the LMV358QPWRG4Q1 datasheet, LMV358QPWRG4Q1 pinout, LMV358QPWRG4Q1 application, or LMV358QPWRG4Q1 equivalent, key selection criteria include its AEC-Q100 qualification, rail-to-rail output capability at low voltage, input common-mode range extending to ground, and TSSOP-8 package compatibility with space-constrained automotive PCB layouts.
Technical Context
The LMV358QPWRG4Q1 integrates two independent high-precision op-amps in a single monolithic die, each featuring p-channel input differential pairs enabling rail-to-rail output swing and ground-sensing input capability. Its internal biasing supports stable operation down to 2.7 V while maintaining 60° phase margin and 10 dB gain margin under 2-kΩ load conditions.
Designed specifically for automotive environments, it incorporates ESD protection exceeding 2-kV HBM, operates over full −40°C to 125°C junction temperature range, and meets AEC-Q100 Grade 1 requirements. The device exhibits no crossover distortion and maintains CMRR ≥50 dB and PSRR ≥50 dB across its operating voltage and temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct interface with 3.3-V and 5-V automotive microcontrollers without level-shifting. |
| Unity-Gain Bandwidth | 1 MHz - supports medium-speed signal conditioning such as throttle position or cabin temperature sensor amplification. |
| Slew Rate | 1 V/µs - sufficient for <100-kHz small-signal applications without distortion in battery monitoring or LIN transceiver biasing. |
| Input Offset Voltage | 7 mV max (typical 1.7 mV) - ensures ≤0.7% error in 1-V full-scale sensor outputs without trimming. |
| Supply Current per Amplifier | 210 µA typical - allows dual-amplifier operation within 420 µA total, critical for always-on vehicle subsystems. |
| Output Swing (RL = 10 kΩ) | VCC − 10 mV (high), 60 mV above GND (low) - delivers true rail-to-rail dynamic range for ADC input driving. |
| Operating Temperature | −40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications. |
Pinout & Package
TSSOP-8 (PW) package: 3.0 mm × 4.4 mm, 0.65 mm pitch, thermally enhanced layout with exposed pad (not electrically connected), RoHS-compliant green finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives downstream circuitry; rail-to-rail swing supports full ADC input utilization. |
| 2 | IN− A | Inverting input of Amplifier A - accepts feedback network or differential sensor signals. |
| 3 | IN+ A | Non-inverting input of Amplifier A - connects to reference voltage or sensor high-side signal. |
| 4 | GND | Analog ground reference - must be tied to system ground plane with low-impedance connection. |
| 5 | IN+ B | Non-inverting input of Amplifier B - enables dual-channel sensing (e.g., temperature + humidity). |
| 6 | IN− B | Inverting input of Amplifier B - used for precision gain-setting or comparator hysteresis. |
| 7 | OUT B | Amplifier B output - independent channel for auxiliary signal path or redundancy. |
| 8 | VCC+ | Positive supply - decoupling capacitor (0.1 µF) required within 5 mm of this pin for stability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358QDRQ1 | SOIC-8 package (4.9 mm × 3.9 mm), higher θJA (97°C/W), same electrical specs. | Better suited for manual assembly or legacy board designs with SOIC footprints. | Select when board layout uses SOIC-8 land pattern or requires easier reworkability. |
| TSV912IQDT | Higher GBW (8 MHz), lower input offset (1.5 mV typ), but higher ICC (820 µA), not AEC-Q100 qualified. | Applicable in non-automotive industrial systems requiring higher speed or precision. | Choose only for non-automotive applications where AEC-Q100 compliance is unnecessary and speed outweighs power budget. |
Compared with LMV358QDRQ1 and TSV912IQDT, the LMV358QPWRG4Q1 uniquely balances AEC-Q100 Grade 1 qualification, TSSOP-8 space efficiency, and ultra-low 420-µA dual-channel quiescent current-making it optimal for modern compact automotive ECUs where thermal density and qualification rigor are mandatory.

FAQ
What is the maximum operating junction temperature for LMV358QPWRG4Q1?
The LMV358QPWRG4Q1 has a maximum operating virtual junction temperature (TJ) of 150°C, as specified in its absolute maximum ratings. This limit ensures reliable operation under worst-case automotive thermal conditions, including simultaneous high ambient temperature and internal power dissipation. Designers must verify actual TJ using θJA = 149°C/W (TSSOP-8) and measured power dissipation to remain within this bound.
Does LMV358QPWRG4Q1 support single-supply operation below 3.3 V?
Yes, LMV358QPWRG4Q1 supports single-supply operation from 2.7 V to 5.5 V. At 2.7 V, it maintains 1-MHz unity-gain bandwidth, 1-V/µs slew rate, and rail-to-rail output swing (within 100 mV of rails at 2-kΩ load). Its input common-mode range extends to ground, enabling direct interfacing with low-voltage sensors and microcontrollers.
Is LMV358QPWRG4Q1 pin-compatible with standard LM358 devices?
No, LMV358QPWRG4Q1 is not pin-compatible with legacy LM358. While both are dual op-amps in 8-pin packages, LMV358QPWRG4Q1 uses TSSOP-8 (PW) with pin 1 = OUT A, whereas LM358 uses DIP/SOIC-8 with pin 1 = NC or COMP. Electrical differences-including rail-to-rail output, lower supply voltage range, and AEC-Q100 qualification-further preclude drop-in replacement without schematic and layout revision.
What is the input bias current specification for LMV358QPWRG4Q1 at 125°C?
At the full operating temperature range (−40°C to +125°C), the input bias current for LMV358QPWRG4Q1 is specified at 500 nA maximum. This value reflects worst-case leakage across process, voltage, and temperature extremes. At 25°C and 5 V supply, typical input bias current is 15 nA, rising predictably with temperature due to p-channel input stage characteristics.
Can LMV358QPWRG4Q1 drive capacitive loads directly?
LMV358QPWRG4Q1 can drive moderate capacitive loads (≤100 pF) stably with 2-kΩ series resistance at the output. For larger loads (e.g., >500 pF), external isolation (e.g., 10-Ω series resistor) is required to maintain ≥60° phase margin, as confirmed by stability curves in Figures 3–4 of the datasheet. Uncompensated direct driving of >1-nF loads risks oscillation.
