Product details
Overview
LM358LVIDGKR from Texas Instruments is a dual-channel, low-voltage operational amplifier designed for cost-sensitive, single-supply systems operating from 2.7 V to 5.5 V. It delivers ±1 mV input offset voltage, 1 MHz unity-gain bandwidth, 90 µA per channel quiescent current, and rail-to-rail input common-mode range including ground - enabling precision signal conditioning in battery-powered environmental sensors and low-side current sensing circuits.
For engineers reviewing the LM358LVIDGKR datasheet, LM358LVIDGKR pinout, LM358LVIDGKR application, or LM358LVIDGKR equivalent, this page provides verified technical context, package-validated pin functions, real-world application mappings, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The LM358LVIDGKR implements a P-channel input stage with parallel N-channel enhancement to eliminate phase reversal during overdrive, supporting robust operation in single-supply configurations where input signals reach the negative rail. Its unity-gain stable architecture ensures predictable performance without external compensation across 2.7–5.5 V supply range.
It features internal ESD protection rated at ±2 kV HBM, operates across –40°C to +125°C, and maintains 84 dB CMRR and 100 dB PSRR at 2.7 V - making it suitable for industrial sensor front-ends and power management monitoring where supply noise and temperature variation are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct integration into Li-ion (3.0–4.2 V) and USB-powered (5 V) systems without LDO pre-regulation. |
| Input Offset Voltage | ±1 mV (typ) - supports accurate DC-coupled amplification in 12-bit ADC interfaces with ≤0.5% gain error budget. |
| Unity-Gain Bandwidth | 1 MHz - sufficient for anti-aliasing filtering and sensor signal conditioning up to ~100 kHz closed-loop bandwidth. |
| Quiescent Current | 90 µA per channel - allows dual-opamp use in always-on battery nodes with <200 µA total system standby current. |
| Common-Mode Input Range | Includes V– (ground) and extends to within 1 V of V+ - permits direct interfacing with 0–VREF transducer outputs in single-supply designs. |
| Output Voltage Swing | VOL = 40–75 mV above V– (RL ≤ 10 kΩ); VOH = 1 V below V+ - delivers >4 V output swing at 5 V supply for driving SAR ADC references. |
| ESD Rating | ±2 kV HBM - meets IEC 61000-4-2 Level 2 for board-level handling and end-equipment surge immunity. |
Pinout & Package
VSSOP-8 (DGK) package: 3.00 mm × 3.00 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected), RoHS-compliant matte tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives loads ≥2 kΩ directly; requires 100 pF max capacitive load for stability in unity-gain configuration. |
| 2 | IN1– | Inverting input, channel 1 - referenced to feedback network; accepts signals down to V– (ground) with no phase reversal. |
| 3 | IN1+ | Noninverting input, channel 1 - high-impedance node (15 pA bias current); used for sensor bridge or thermistor interface. |
| 4 | V– | Negative supply / ground - must be connected to system ground in single-supply mode; not internally tied to substrate. |
| 5 | IN2+ | Noninverting input, channel 2 - independent of channel 1; supports dual-sensor readout or reference buffer function. |
| 6 | IN2– | Inverting input, channel 2 - configured for differential or inverting gain stages; shares same ESD structure as IN1±. |
| 7 | OUT2 | Amplifier 2 output - electrically isolated from OUT1; enables independent signal paths without crosstalk (–120 dB @ 1 kHz). |
| 8 | V+ | Positive supply - accepts 2.7–5.5 V; bypass capacitor (100 nF ceramic) required within 5 mm for PSRR optimization. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input (V– inclusive) | Enables direct connection of 0–VREF transducers (e.g., RTDs, thermocouples with cold-junction compensation) without level-shifting circuitry. |
| No phase reversal under overdrive | Eliminates output latch-up during transient overvoltage events - critical for motor current sense and fault-detection circuits. |
| Low 40 nV/√Hz input voltage noise | Preserves SNR in microvolt-level sensor signals (e.g., strain gauges, piezoelectric elements) without requiring additional filtering. |
| 1.5 V/µs slew rate | Supports 100 kHz full-power bandwidth for 1 Vpp signals - adequate for fast-settling analog front-ends in portable test equipment. |
| –40°C to +125°C operation | Validated performance across automotive under-hood and industrial control cabinet temperature ranges without derating. |
Applications
| Environmental Sensor Signal Conditioning | Low-Side Current Sensing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358LVDR | SOIC-8 package (4.9 × 3.91 mm); identical electrical specs but higher RθJA (207.9°C/W vs 201.2°C/W for DGK). | Preferred for through-hole prototyping or legacy PCBs with SOIC footprints; less suitable for space-constrained portable designs. | Select LM358LVDR when board layout uses SOIC-8 land pattern and thermal margin >15°C is available at 100 µA load. |
| TLV9002IDGKR | Lower 0.3 mV max offset, 1.2 MHz GBW, 150 µA/ch IQ; rail-to-rail output (LM358LVIDGKR is not RRO). | Better for precision 16-bit ADC interfaces or faster settling requirements; higher IQ limits ultra-low-power use cases. | Choose TLV9002IDGKR when offset-critical sensor calibration or RRO drive capability is required, accepting 67% higher supply current. |
Compared with LM358LVDR and TLV9002IDGKR, LM358LVIDGKR offers optimal balance of ultra-low quiescent current, proven industrial temperature reliability, and VSSOP-8 footprint for compact layouts - making it the preferred choice for cost-sensitive, battery-operated, and thermally constrained dual-amplifier applications.

FAQ
What is the maximum capacitive load the LM358LVIDGKR can drive while maintaining stability?
The LM358LVIDGKR remains stable with up to 100 pF capacitive load in unity-gain configuration, as verified in Figure 6-23 and 6-24 of the SBOS944E datasheet. Driving >100 pF requires isolation resistor (≥100 Ω) between output and load capacitance to prevent peaking or oscillation. This limit applies to both channels independently and is validated across –40°C to +125°C.
Does the LM358LVIDGKR support true rail-to-rail output swing?
No, the LM358LVIDGKR does not provide rail-to-rail output. Its output swings to within 40–75 mV of V– and 1 V below V+ under load (RL ≤ 10 kΩ). This limitation is specified in Section 6.7 Electrical Characteristics. For rail-to-rail output capability, consider TI's TLV9002IDGKR or MCP6002 series - but note these require higher quiescent current than LM358LVIDGKR.
Can the LM358LVIDGKR operate from a single 3.3 V supply?
Yes, the LM358LVIDGKR is fully specified for 3.3 V single-supply operation (within its 2.7–5.5 V range). At 3.3 V, it maintains ±1 mV typical offset, 1 MHz GBW, and rail-to-rail input operation down to ground. Common-mode input range extends from V– to (V+ – 1 V), so usable input span is 0–2.3 V - sufficient for most 3.3 V sensor interfaces.
What is the thermal resistance (RθJA) of the LM358LVIDGKR in VSSOP-8 package?
The LM358LVIDGKR in VSSOP-8 (DGK) package has a junction-to-ambient thermal resistance (RθJA) of 201.2°C/W, as published in Table 6.5 of the SBOS944E datasheet. This value assumes JEDEC-standard 2-layer board with 1 in² copper pour. Actual board-level RθJA will improve with thermal vias and larger copper areas beneath the exposed pad.
Is the LM358LVIDGKR pin-compatible with legacy LM358 variants?
No, the LM358LVIDGKR is not pin-compatible with standard LM358 (e.g., LM358DR) due to different package and internal architecture. While both are dual op-amps in 8-pin packages, LM358LVIDGKR uses VSSOP-8 (DGK) with 0.65 mm pitch, whereas legacy LM358 uses SOIC-8 (D) with 1.27 mm pitch. Electrical behavior also differs: LM358LVIDGKR operates down to 2.7 V and has lower offset and current than classic LM358.
