Product details
Overview
LM358LVIDDFR 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 LM358LVIDDFR datasheet, LM358LVIDDFR pinout, LM358LVIDDFR application, or LM358LVIDDFR equivalent, this page provides verified technical context, package-specific pin functions, real-world design meaning of key specs, and two validated alternative parts for low-voltage op amp selection in industrial and consumer embedded systems.
Technical Context
The LM358LVIDDFR implements a P-channel input stage with parallel N-channel pair to eliminate phase reversal during overdrive while maintaining rail-to-rail common-mode input (V– to V+ – 1 V). Its unity-gain stable architecture supports stable operation down to 2.7 V supply with 1.5 V/µs slew rate and 75° phase margin at 5.5 V.
It features internal ESD protection rated at ±2 kV HBM, operates across –40°C to +125°C, and achieves 40 nV/√Hz input voltage noise density and 0.005% THD+N at 1 kHz - making it suitable for low-power analog front-ends where supply headroom and thermal robustness are constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct integration into Li-ion, USB-powered, and 3.3 V logic-compatible systems without level-shifting. |
| Input Offset Voltage | ±1 mV (typ) - ensures ≤10 mV error in 10× gain configurations, critical for accurate sensor signal amplification. |
| Unity-Gain Bandwidth | 1 MHz - supports stable closed-loop operation up to ~100 kHz with moderate gain, sufficient for DC–audio-band conditioning. |
| Quiescent Current | 90 µA per channel - allows dual-amplifier operation on <180 µA total, ideal for always-on battery monitoring nodes. |
| Common-Mode Input Range | V– to V+ – 1 V - permits true single-supply operation with ground-referenced inputs, eliminating need for biasing networks. |
| Output Voltage Swing | 40 mV above V–, 1 V below V+ (RL ≥ 10 kΩ) - delivers usable dynamic range in 3.3 V systems with 2.9 V output swing. |
| ESD Rating | ±2 kV HBM - meets IEC 61000-4-2 Level 2 requirements for handling robustness in manufacturing and field deployment. |
Pinout & Package
SOT-23-8 (DDF) package: 2.90 mm × 1.60 mm body, 0.65 mm pitch, surface-mount, thermally enhanced for compact PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives loads ≥2 kΩ directly; limited sourcing/sinking capability requires external buffering for >10 mA. |
| 2 | IN1– | Inverting input, channel 1 - high-impedance node (≤15 pA bias current); sensitive to layout-induced leakage and capacitive coupling. |
| 3 | IN1+ | Noninverting input, channel 1 - accepts signals from V– to V+ – 1 V; no phase reversal when driven beyond rails within safe limits. |
| 4 | V– | Negative supply or ground reference - must be low-impedance; shared with all channels; not internally connected to substrate. |
| 5 | IN2+ | Noninverting input, channel 2 - electrically isolated from channel 1; supports independent signal paths with 80 dB typical channel separation. |
| 6 | IN2– | Inverting input, channel 2 - matched to IN1– in offset and bias; enables differential or feedback configurations without cross-talk penalty. |
| 7 | OUT2 | Amplifier 2 output - identical performance to OUT1; may be paralleled only with external current-sharing resistors. |
| 8 | V+ | Positive supply - decoupling capacitor (≥100 nF ceramic) required within 5 mm for stability under transient load conditions. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input (V– inclusive) | Enables direct interface with ground-referenced transducers (e.g., thermistors, current shunts) without input biasing circuitry. |
| No phase reversal on overdrive | Eliminates output latch-up risk in comparator-like applications or fast transient detection, improving system reliability. |
| Low 40 nV/√Hz input noise | Preserves SNR in microvolt-level sensor outputs (e.g., RTDs, strain gauges), reducing need for post-amplification filtering. |
| 1.5 V/µs slew rate | Supports clean 100 kHz sine wave reproduction at 1 Vpp, suitable for active filters and buffered reference scaling. |
| –40°C to +125°C operation | Validated performance across automotive cabin, industrial control, and outdoor IoT environments without derating. |

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 |
|---|---|---|---|
| TLV2372IDR | Lower 55 µA/ch quiescent current, but higher 2.5 mV max offset and 0.55 MHz GBW. | Better for ultra-low-power sleep modes; less suitable for precision DC gain stages requiring <2 mV error. | Select TLV2372IDR only when sub-60 µA total supply current is mandatory and offset tolerance >2 mV is acceptable. |
| LM358DR | Higher 350 µA/ch IQ, wider 3–32 V supply range, but same pinout and basic functionality. | Compatible with legacy 5 V/12 V designs; unsuitable for 2.7–3.6 V battery systems due to minimum supply limit. | Choose LM358DR for backward compatibility in existing 5 V boards; avoid for new low-voltage designs targeting <3.6 V operation. |
Compared with TLV2372IDR and LM358DR, LM358LVIDDFR uniquely balances ultra-low power (90 µA/ch), precision (±1 mV VOS), and true 2.7 V operation - making it optimal for next-generation compact, battery-efficient sensor nodes where both accuracy and energy efficiency are constrained.

FAQ
What is the maximum operating temperature for LM358LVIDDFR?
The LM358LVIDDFR is specified for continuous operation from –40°C to +125°C ambient temperature. Its thermal design supports junction temperatures up to 150°C, and the SOT-23-8 (DDF) package exhibits 183.7°C/W junction-to-ambient resistance - enabling reliable use in enclosed industrial enclosures or near heat sources when properly heatsinked.
Does LM358LVIDDFR support single-supply operation with ground-referenced inputs?
Yes. The LM358LVIDDFR features a P-channel input stage that extends the common-mode input voltage range to include the negative supply rail (V–), allowing true single-supply operation with inputs referenced to ground. This eliminates the need for input biasing networks in sensor interfaces and current-sense applications.
What is the output voltage swing capability of LM358LVIDDFR at 3.3 V supply?
At VS = 3.3 V, the LM358LVIDDFR delivers a minimum output swing of 40 mV above V– and 1 V below V+, yielding a usable range of 0.04 V to 2.3 V (2.26 V total). This provides adequate headroom for driving 12-bit SAR ADCs or interfacing with 3.3 V logic comparators without external level-shifting.
Is LM358LVIDDFR pin-compatible with standard LM358 packages?
No. LM358LVIDDFR uses the SOT-23-8 (DDF) package, which is physically and electrically distinct from the industry-standard SOIC-8 (D) or PDIP-8 footprints. While pin functions match the LM358 family (e.g., Pin 1 = OUT1, Pin 2 = IN1–), the DDF package requires dedicated PCB layout and reflow profile optimization.
How does the ESD protection of LM358LVIDDFR compare to legacy LM358 variants?
The LM358LVIDDFR features enhanced ±2 kV HBM ESD protection - double the rating of most legacy LM358 variants (typically ±1 kV). This improvement stems from TI's optimized input-stage clamping diodes and internal absorption cell, significantly increasing robustness during automated assembly and field handling without external TVS components.
