Product details
Overview
LM358ST from STMicroelectronics is a low-power dual operational amplifier in MiniSO8 package, rated for 0 °C to 70 °C operation, with 1.1 MHz unity-gain bandwidth, 100 dB large-signal voltage gain, and rail-to-rail output swing (0 V to VCC − 1.5 V) - widely deployed in sensor signal conditioning and industrial DC amplification circuits.
For engineers reviewing the LM358ST datasheet, LM358ST pinout, LM358ST application, or LM358ST equivalent, key selection criteria include input offset voltage (2 mV max), supply current per channel (≤1.2 mA at 5 V), common-mode input range extending to negative rail, and compatibility with single-supply 3–30 V systems without level-shifting circuitry.
Technical Context
This dual op-amp integrates two independent, internally frequency-compensated high-gain amplifiers optimized for single-supply operation. Its input stage uses PNP transistors enabling common-mode voltage range down to ground, while the output stage delivers 40 mA source/20 mA sink capability with 0.6 V/µs typical slew rate.
It features temperature-compensated biasing (20 nA max input bias current, 2 nA max input offset current) and robust ESD protection (300 V HBM). The device operates across 3–30 V supply with supply current essentially independent of voltage magnitude - critical for battery-powered and logic-compatible 5 V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 30 V - supports direct interface with 5 V logic rails and higher-voltage industrial supplies without regulation. |
| Unity-Gain Bandwidth | 1.1 MHz - enables stable AC-coupled amplification up to audio frequencies with minimal phase shift. |
| Large-Signal Voltage Gain | 100 dB - provides ≥100,000× open-loop gain for precise DC gain blocks and transducer amplification. |
| Input Offset Voltage | 2 mV (max) - ensures ≤2 mV baseline error in precision DC amplifiers without external trimming. |
| Output Voltage Swing | 0 V to (VCC − 1.5 V) - allows near-ground-level output in single-supply configurations, simplifying level-referenced sensing. |
| Supply Current (per channel) | 1.2 mA (max at 25 °C, 5 V) - enables low-power operation in always-on sensor nodes and portable instrumentation. |
| Input Common-Mode Range | Includes negative rail (GND) - permits direct connection of grounded sensors (e.g., thermocouples, strain gauges) without bias resistors. |
Pinout & Package
LM358ST is housed in an 8-pin MiniSO8 package (3.0 mm × 3.0 mm, 0.65 mm pitch), optimized for space-constrained PCB layouts while maintaining thermal performance (RthJA = 190 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Amplifier A output - drives loads up to 40 mA source / 20 mA sink; swings 0 V to VCC − 1.5 V. |
| 2 | Inverting Input A | High-impedance (≥200 kΩ) differential input node for A amplifier; accepts signals down to GND. |
| 3 | Non-Inverting Input A | High-impedance input for A amplifier; supports rail-to-rail common-mode range including GND. |
| 4 | GND | Power and signal reference ground - must be low-impedance return path for both amplifiers and load currents. |
| 5 | Non-Inverting Input B | Independent input for B amplifier; electrically isolated from A section with >120 dB channel separation. |
| 6 | Inverting Input B | Differential input for B amplifier; shares same bias and offset specs as Pin 2. |
| 7 | Output B | Second independent output - identical drive capability and swing range as Pin 1. |
| 8 | VCC | Positive supply rail - accepts 3–30 V; supply current draw is voltage-independent for stable power budgeting. |
Key Features
| Feature | Design Value |
|---|---|
| Internally frequency-compensated | Guarantees unity-gain stability without external compensation components - reduces BOM count and layout complexity. |
| Rail-to-rail input common-mode range | Accepts inputs from GND to VCC − 2 V across full temperature range - eliminates need for input bias networks in single-supply designs. |
| Low input bias current (20 nA) | Minimizes voltage error across high-impedance sources (e.g., pH electrodes, photodiode transimpedance feedback) without active guarding. |
| Temperature-compensated offset & drift | 2 mV max offset and 7–15 µV/°C drift ensure stable DC accuracy over 0–70 °C ambient - suitable for uncalibrated industrial sensors. |
| Single-supply optimized architecture | Operates from 3–30 V with no dual-rail requirement - directly interfaces with microcontroller ADCs, DACs, and logic I/O at 5 V or 3.3 V. |
Applications
| Transducer Signal Conditioning | DC Gain Block for Industrial Sensors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DT | Same electrical specs but SO8 package (larger footprint, lower thermal resistance: 125 °C/W vs. 190 °C/W). | Preferred for higher-power or thermally constrained designs where board area is not limiting. | Select LM358DT when thermal dissipation >150 mW is expected or legacy SO8 layout reuse is required. |
| LM2904DT | Automotive-grade variant (−40 °C to +105 °C), identical pinout and core specs, enhanced ESD (2 kV HBM). | Required for automotive body electronics, ADAS sensor interfaces, or industrial equipment requiring extended temperature qualification. | Choose LM2904DT for AEC-Q100 compliance, higher reliability screening, or operation beyond 70 °C ambient. |
Compared with LM358ST, LM358DT offers better thermal performance in larger packages but occupies more PCB area, while LM2904DT adds automotive qualification and ESD robustness at no functional trade-off - making LM358ST optimal for cost-sensitive, space-constrained commercial-grade 0–70 °C applications.

FAQ
Is LM358ST pin-compatible with other LM358 variants like LM358DT or LM358PT?
Yes - LM358ST (MiniSO8), LM358DT (SO8), and LM358PT (TSSOP8) share identical pin numbering and electrical functionality. Mechanical differences affect PCB footprint and thermal performance only; no schematic or layout changes are needed when substituting between these packages.
Can LM358ST operate from a 3.3 V supply, and what is its output swing at that voltage?
Yes, LM358ST is fully specified down to 3 V supply. At 3.3 V, the output swings from 0 V to approximately 1.8 V (VCC − 1.5 V), supporting direct interfacing with 3.3 V ADC references. Output drive remains functional, though source/sink current decreases slightly versus 5 V operation.
Does LM358ST require external frequency compensation components?
No - LM358ST incorporates internal frequency compensation optimized for unity-gain stability. No external capacitors or resistors are needed for stable operation in standard inverting/non-inverting configurations, reducing bill-of-materials and layout sensitivity.
What is the maximum capacitive load LM358ST can drive without oscillation?
LM358ST maintains stability with ≤100 pF capacitive loads under typical conditions. For heavier loads (e.g., >200 pF), a series resistor (10–100 Ω) between output and load is recommended to isolate capacitance and preserve phase margin - verified in Figure 18 of the datasheet.
