Product details
Overview
LMV358IDDURG4 from Texas Instruments is a dual, rail-to-rail output operational amplifier optimized for low-voltage (2.7 V to 5.5 V) single-supply operation, delivering 1 MHz unity-gain bandwidth, 1 V/μs slew rate, and 210 μA typical supply current per amplifier - used in motor control feedback loops, HVAC sensor signal conditioning, and portable media player audio stages.
For engineers reviewing the LMV358IDDURG4 datasheet, LMV358IDDURG4 pinout, LMV358IDDURG4 application, or LMV358IDDURG4 equivalent, this page provides verified package mapping (VSSOP-8), confirmed dual-channel rail-to-rail output behavior, thermal resistance (RθJA = 201.2°C/W), ESD ratings (2000-V HBM), and real-world application constraints including input common-mode range down to ground and output swing within 100 mV of rails at 2.7 V.
Technical Context
The LMV358IDDURG4 implements a complementary-input-stage architecture enabling rail-to-rail output swing while maintaining stable phase margin (60°) and gain margin (10 dB) across 2.7 V–5.5 V supply range. Its input stage operates with common-mode voltage extending to GND, eliminating need for level-shifting in single-supply sensor interfaces.
It features no crossover distortion and supports unity-gain stable operation into capacitive loads up to 1000 pF (per Figure 6-3–6-4), with specified output short-circuit current of ±40 mA at 25°C - critical for driving resistive transducers or LED bias networks without external current limiting.
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 (3.0–4.2 V) and 3.3-V logic without LDO regulation |
| Unity-Gain Bandwidth | 1 MHz - supports closed-loop gain ≥10 up to ~100 kHz with <1% gain error in active filters and sensor amplifiers |
| Slew Rate | 1 V/μs - limits full-scale step response time to ≤1 μs for 1-V output transitions, suitable for DC-coupled audio and motor position feedback |
| Input Offset Voltage | 1.7 mV (min), 7 mV (typ) - ensures ≤0.7% error in 1-V reference-based current-sense applications at room temperature |
| Output Swing (2.7 V) | VOH ≥ VCC – 100 mV, VOL ≤ 180 mV - delivers true rail-to-rail dynamic range for ADC input buffering with 12-bit ENOB preservation |
| ESD Rating (HBM) | 2000 V - meets IEC 61000-4-2 Level 2 for board-level handling without additional protection circuitry |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive HVAC actuators and industrial motor drives |

| 3 (1IN+) | Amplifier 1 noninverting input | High-impedance node (IIB = 15 nA typ); minimal loading on high-Z sensors |
| 4 (GND) | Negative supply reference | Must be low-impedance plane; shared return for both amplifiers and bypass caps |
| 5 (2IN+) | Amplifier 2 noninverting input | Independent input path; no crosstalk >90 dB at 1 kHz (Figure 6-26) |
| 6 (2IN–) | Amplifier 2 inverting input | Matches Pin 2 electrical characteristics; supports matched feedback networks |

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 |
|---|---|---|---|
| LMV358IDR | Same silicon, SOIC-8 package (4.9 × 6.0 mm); RθJA = 207.9°C/W vs 201.2°C/W for DDU | Preferred for through-hole prototyping or legacy PCBs with SOIC footprints | Select when thermal budget allows higher junction rise or board space permits larger package |
| TLV2372IDR | Lower IQ (20 μA/ch), lower VIO (1.5 mV max), but only 3-V min supply; not rated for 125°C | Better for ultra-low-power battery devices where temperature range ≤85°C suffices | Choose only if supply ≥3.0 V and ambient <85°C; avoid for automotive or industrial environments |
Compared with LMV358IDDURG4, LMV358IDR offers identical electrical specs in a larger, thermally less efficient package, while TLV2372IDR trades off high-temperature capability and supply flexibility for ultra-low quiescent current - making LMV358IDDURG4 the optimal choice for cost-sensitive, wide-temperature, rail-to-rail applications in compact designs.

FAQ
What is the maximum operating supply voltage for LMV358IDDURG4?
The absolute maximum supply voltage for LMV358IDDURG4 is 5.5 V, with recommended operation between 2.7 V and 5.5 V. Exceeding 5.5 V risks permanent damage per Absolute Maximum Ratings (Section 6.1). At 5.5 V, output swing remains rail-to-rail, and supply current increases to 440 μA (typ) per amplifier - verified in Section 6.8 Electrical Characteristics.
Does LMV358IDDURG4 support true rail-to-rail input?
No, LMV358IDDURG4 does not support rail-to-rail input. Its common-mode input voltage range extends to GND (–0.2 V minimum) but only up to VCC – 1.2 V maximum at 25°C (Section 6.8 VICR). This allows ground-referenced sensor interfaces but requires input signals to stay ≥1.2 V below VCC for full CMRR performance.
Can LMV358IDDURG4 drive capacitive loads without oscillation?
Yes, LMV358IDDURG4 is unity-gain stable with capacitive loads up to 1000 pF when driving 600-Ω or 2-kΩ resistive loads (Figures 6-3 to 6-4). For loads >1000 pF, a series isolation resistor (≥10 Ω) is required at the output to maintain phase margin ≥60° - confirmed in Typical Characteristics section and Application Note SLOA099.
What is the thermal resistance (RθJA) of LMV358IDDURG4 in its VSSOP-8 package?
The junction-to-ambient thermal resistance (RθJA) for LMV358IDDURG4 in the DDU (VSSOP-8) package is 201.2°C/W, as specified in Section 6.6 Thermal Information. This value assumes standard JEDEC 2-layer board layout; adding copper pour under the exposed pad reduces effective RθJA by ~15°C/W.
Is LMV358IDDURG4 pin-compatible with LM358?
No, LMV358IDDURG4 is not pin-compatible with LM358. While both are dual op-amps in 8-pin packages, LM358 uses SOIC-8 pinout (OUT, –IN, +IN, GND, +IN, –IN, OUT, VCC), whereas LMV358IDDURG4 (VSSOP-8) follows TI's standard dual-op-amp pinout: OUT, –IN, +IN, GND, +IN, –IN, OUT, VCC+. Physical pin alignment differs, and LM358 lacks rail-to-rail output.
