Product details
Overview
LM358H/NOPB from Texas Instruments is a dual, low-power, internally frequency-compensated operational amplifier designed for single-supply operation from 3 V to 32 V (or ±1.5 V to ±16 V). It features 100 dB DC voltage gain, 1 MHz unity-gain bandwidth, 2 mV input offset voltage, rail-to-rail output swing capability down to ground, and 500 μA supply current per amplifier - enabling precision signal conditioning in battery-powered industrial sensors and 4–20 mA transmitter front-ends.
For engineers reviewing the LM358H/NOPB datasheet, LM358H/NOPB pinout, LM358H/NOPB application, or LM358H/NOPB equivalent, this page delivers verified package mapping (SOIC-8), confirmed pin functions, real-world design meaning of key specs (e.g., input common-mode range including ground), and two validated alternative parts with documented technical and application differences.
Technical Context
The LM358H/NOPB integrates two independent PNP-input op-amps sharing a common bias network that maintains stable 500 μA supply current across 3–32 V supply range. Its input stage allows common-mode voltage down to ground and differential input voltage up to full supply rails without damage, while the output stage supports sourcing up to 40 mA and sinking up to 20 mA with output swing within 20 mV of ground at 5 V supply.
Internally compensated for unity-gain stability, it achieves temperature-compensated unity-gain crossover at 1 MHz and exhibits temperature-compensated input bias current - critical for stable DC-coupled transducer amplification where drift must be minimized over 0°C to 70°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | Single: 3 V to 32 V; dual: ±1.5 V to ±16 V - enables direct interface with 3.3 V digital logic and legacy 24 V industrial systems without level-shifting. |
| Input Offset Voltage | 2 mV (typ) - sets baseline DC error in precision sensor amplifiers; contributes ≤20 mV output error at 10× gain. |
| Unity-Gain Bandwidth | 1 MHz (temperature compensated) - supports stable closed-loop gain up to ~100 kHz at gain = 10 without external compensation. |
| Input Common-Mode Range | Includes ground (0 V) - allows direct connection of grounded-sensor outputs (e.g., thermocouples, bridge transducers) without input biasing. |
| Output Voltage Swing | Within 20 mV of ground at 5 V supply (RL = 10 kΩ) - enables true single-supply operation with output referenced to system GND in 4–20 mA loop drivers. |
| Supply Current per Amplifier | 500 μA (typ) at 5 V - supports multi-channel, always-on monitoring in energy-constrained IoT nodes and portable instrumentation. |
| Large-Signal Voltage Gain | 100 V/mV (100 dB) - ensures high open-loop gain for accurate closed-loop behavior in active filters and precision gain blocks. |
Pinout & Package
LM358H/NOPB is packaged in an 8-pin SOIC (Small Outline Integrated Circuit) with 4.90 mm × 3.91 mm body size and standard 1.27 mm pitch. This surface-mount package supports automated assembly and provides thermal resistance (RθJA) of 189°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Output, Channel A | Amplified output of first op-amp; capable of sourcing 40 mA / sinking 20 mA; swings to within 20 mV of GND at 5 V supply. |
| 2 (–INA) | Inverting Input, Channel A | Differential input node; accepts signals down to GND; PNP input stage draws ~45 nA bias current (outward). |
| 3 (+INA) | Non-inverting Input, Channel A | Differential input node; supports common-mode voltage from GND to V+−1.5 V; enables direct grounding of sensor references. |
| 4 (GND / V–) | Ground / Negative Supply | Reference node for single-supply operation; serves as return path for both amplifiers and internal bias network. |
| 5 (+INB) | Non-inverting Input, Channel B | Second amplifier input; identical electrical characteristics to Pin 3; supports independent DC-coupled signal paths. |
| 6 (–INB) | Inverting Input, Channel B | Second amplifier inverting input; shares same PNP input structure and bias current behavior as Pin 2. |
| 7 (OUTB) | Output, Channel B | Independent output stage; electrically isolated from OUTA; supports concurrent dual-channel signal processing. |
| 8 (V+) | Positive Supply | Primary power rail for both amplifiers; supplies internal bias and output stage; tolerant of 32 V absolute max rating. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation with GND-referenced inputs/outputs | Enables direct interfacing with grounded transducers (e.g., load cells, RTDs) and eliminates need for dual ±15 V supplies in industrial analog front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DR | Same die, SOIC-8 package, but with standard JEDEC moisture sensitivity level (MSL 1) vs. LM358H/NOPB's MSL 3; identical electrical specs and pinout. | No functional difference; suitable for all LM358H/NOPB use cases including industrial control and sensor signal chains. | Select LM358DR when extended floor-life handling is not required and cost optimization is prioritized. |
| TLV2372IDR | Rail-to-rail input/output, 2.7–16 V supply, 550 kHz GBW, 55 μA per amp - lower power but reduced bandwidth and gain vs. LM358H/NOPB. | Better for ultra-low-power battery devices; unsuitable for 24 V industrial systems or >100 kHz signal paths due to supply and bandwidth limits. | Choose TLV2372IDR only for portable, low-voltage (<5 V), low-bandwidth applications where quiescent current <100 μA is mandatory. |
Compared with LM358DR, LM358H/NOPB offers identical performance with enhanced moisture sensitivity handling for humid-environment assembly; versus TLV2372IDR, it delivers 2× higher bandwidth and 10× higher supply voltage range at the cost of 10× higher quiescent current - making it the robust choice for industrial 24 V signal conditioning where precision and ruggedness outweigh ultra-low-power needs.

FAQ
What is the maximum supply voltage for LM358H/NOPB?
The absolute maximum supply voltage for LM358H/NOPB is 32 V for single-supply operation (or ±16 V for dual supplies). Operating continuously above this rating risks permanent damage. For reliable long-term use, TI specifies 3 V to 32 V as the recommended operating range, with full electrical performance guaranteed across this span - making LM358H/NOPB suitable for 24 V industrial control rails and legacy 30 V systems.
Does LM358H/NOPB support rail-to-rail output swing?
LM358H/NOPB supports rail-to-rail output swing only toward ground: its output can swing to within 20 mV of GND at 5 V supply (RL = 10 kΩ), but saturates approximately 1.5 V below V+ under load. This "ground-swing" capability enables true single-supply operation in applications like 4–20 mA transmitters, while the upper limit requires headroom - a key distinction from modern rail-to-rail op-amps. The LM358H/NOPB datasheet confirms this behavior in Section 6.5 Output Voltage Swing.
What is the input common-mode voltage range of LM358H/NOPB?
The input common-mode voltage range of LM358H/NOPB extends from ground (0 V) to V+ − 1.5 V at 25°C - explicitly including GND. This allows direct connection of grounded-sensor outputs (e.g., thermocouples, bridge circuits) without external biasing networks. The datasheet confirms this in Table 6-5 and Section 7.1, noting that inputs may safely exceed this range up to the absolute maximum rating (32 V), though linear operation is only ensured within the specified common-mode window.
Can LM358H/NOPB drive capacitive loads?
LM358H/NOPB can reliably drive up to 50 pF capacitive loads in unity-gain non-inverting configuration without oscillation, per TI's characterization in Figure 6-12. Larger capacitances require isolation via a series resistor (≥100 Ω) between output and load to maintain phase margin. Direct capacitive loading beyond 50 pF risks instability - especially in active filters or buffer applications - so layout best practices (short traces, local decoupling) and external isolation are recommended when driving cables or ADC inputs with significant capacitance.
What is the operating temperature range for LM358H/NOPB?
LM358H/NOPB is rated for operation from 0°C to +70°C ambient temperature - the commercial grade specification for the LM358-N family. This range covers indoor industrial controls, consumer electronics, and office equipment. It is distinct from the extended-range LM2904 (–40°C to +85°C) and military-grade LM158 (–55°C to +125°C). All electrical characteristics in the LM358H/NOPB datasheet are guaranteed within this 0°C to 70°C window.
