Product details
Overview
LM358S-13 from Diodes Incorporated is a low-power dual operational amplifier in SOP-8L package, designed for single-supply operation from 3V to 32V, featuring 1 MHz unity-gain bandwidth, 100 dB large-signal voltage gain, and rail-to-ground input common-mode range including 0 V. It enables transducer amplification, DC gain blocks, and sensor interface circuits in battery-powered and industrial control systems.
For engineers reviewing the LM358S-13 datasheet, LM358S-13 pinout, LM358S-13 application, or LM358S-13 equivalent, key selection criteria include input offset voltage (2 mV typ), supply current (500 μA typ), output swing (0 V to V+ – 1.5 V), and single-supply compatibility down to 3 V - critical for embedded analog front-ends and cost-sensitive signal conditioning.
Technical Context
The LM358S-13 integrates two independent, internally frequency-compensated op amps with PNP input stages enabling true ground-sensing capability and differential input voltage tolerance up to ±32 V. Its bias network delivers supply-current stability across 3–30 V, and temperature-compensated unity-gain bandwidth ensures consistent small-signal response.
Input common-mode range extends from ground to V+ – 1.5 V at 25°C, while output can sink to 0 V and source up to V+ – 1.5 V into 2 kΩ, supporting rail-referenced sensing and unipolar signal processing without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | Single supply: 3 V to 32 V - supports direct interfacing with 5 V digital logic and 24 V industrial rails without regulation. |
| Unity-Gain Bandwidth | 1 MHz (temperature compensated) - enables stable AC-coupled amplification up to ~100 kHz at moderate closed-loop gains. |
| Large-Signal Voltage Gain | 100 dB (25–100 V/mV) - provides ≥100× open-loop gain for precision DC amplification with <0.01% gain error at G = 10. |
| Input Offset Voltage | 2 mV (typ), 7 mV (max) - sets baseline DC error floor for sensor amplifiers; requires trimming only in sub-mV accuracy applications. |
| Supply Current per Amplifier | 500 μA (typ), 1.2 mA (max at 5 V) - enables multi-channel analog signal chains in power-constrained systems (e.g., portable instrumentation). |
| Output Voltage Swing | 0 V to V+ – 1.5 V (RL = 2 kΩ) - allows full-scale output near ground for single-supply ADC drivers and comparator reference buffers. |
| Input Common-Mode Range | 0 V to V+ – 1.5 V - permits direct connection of grounded sensors (e.g., thermistors, strain gauges) without input biasing resistors. |
Pinout & Package
SOP-8L (Small Outline Package, 8-pin, lead-free, RoHS-compliant) with standard JEDEC MS-012AC footprint and 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTPUT 1 | Channel 1 analog output node; capable of sourcing 20 mA / sinking 70 μA (at V+ = 5 V) with rail-to-ground swing. |
| 2 | INVERTING INPUT 1 | Inverting input of Channel 1; accepts signals from 0 V to V+ – 1.5 V; input bias current 45 nA (typ) flows out of pin. |
| 3 | NON-INVERTING INPUT 1 | Non-inverting input of Channel 1; identical voltage range and bias current behavior as Pin 2. |
| 4 | GND | Analog ground reference for both amplifiers; must be low-impedance return path for input/output currents and supply decoupling. |
| 5 | NON-INVERTING INPUT 2 | Non-inverting input of Channel 2; electrically isolated from Channel 1 but shares same GND and V+ supply domains. |
| 6 | INVERTING INPUT 2 | Inverting input of Channel 2; matches Pin 2 electrical characteristics and layout sensitivity. |
| 7 | OUTPUT 2 | Channel 2 analog output node; functionally identical to Pin 1 with independent loading and thermal behavior. |
| 8 | V+ | Positive supply rail for both amplifiers; accepts 3–32 V DC; internal bias network draws current independent of V+ magnitude. |
Key Features
| Feature | Design Value |
|---|---|
| Internally frequency compensated | Stable unity-gain operation without external compensation components - reduces BOM count and layout sensitivity. |
| Input common-mode range includes ground | Enables direct interface with 0 V-referenced sensors (e.g., current-sense shunts, RTDs) without input bias networks or level shifters. |
| Output swing to 0 V | Supports single-supply ADC input buffering and comparator reference generation where negative rail is unavailable. |
| Low supply current (500 μA typ) | Permits integration of dual op amp functionality in always-on monitoring nodes with <1 mW quiescent power at 5 V. |
| Wide supply range (3–32 V) | Eliminates need for dedicated analog regulators in mixed-voltage systems - operates directly from 5 V logic rails or 24 V industrial buses. |

FAQ
Can LM358S-13 operate from a 3.3 V supply?
Yes. The LM358S-13 is specified for single-supply operation from 3 V to 32 V. At 3.3 V, it maintains functional input common-mode range (0 V to 1.8 V), output swing (0 V to ~1.8 V), and 1 MHz unity-gain bandwidth, though large-signal voltage gain drops to ~70 dB. It is widely used in 3.3 V microcontroller peripheral circuits.
Does LM358S-13 require external compensation capacitors?
No. The LM358S-13 is internally frequency compensated for stable unity-gain operation. No external compensation is needed for standard inverting/non-inverting configurations. Capacitive loads >50 pF may require series isolation resistance at the output to maintain phase margin.
What is the maximum output current capability?
The LM358S-13 can source up to 40 mA and sink up to 20 mA (at V+ = 15 V, TA = 25°C), but continuous operation above 10 mA requires thermal derating. For sustained 20 mA loads, keep ambient temperature below 50°C and ensure adequate PCB copper area for heat dissipation.
Is LM358S-13 pin-compatible with other LM358 variants?
Yes. LM358S-13 uses the industry-standard SOP-8L package with identical pinout to SOIC-8, TSSOP-8, and MSOP-8 versions of LM358. Footprint compatibility enables drop-in replacement across form factors, provided solder profile and thermal pad design match the SOP-8L mechanical dimensions.
