Product details
Overview
LM358PT from STMicroelectronics is a low-power dual operational amplifier designed for single-supply operation (3–30 V), featuring 100 dB DC gain, 1.1 MHz unity-gain bandwidth, 2 mV input offset voltage, 20 nA input bias current, and rail-to-rail output swing down to 0 V - widely used in sensor signal conditioning, industrial transducer interfaces, and 5 V logic-compatible analog front-ends.
For engineers reviewing the LM358PT datasheet, LM358PT pinout, LM358PT application, or LM358PT equivalent, this page delivers verified electrical specs, SO8 package details, real-world use cases in single-supply systems, and validated alternative options - all grounded in ST's production-grade documentation (DocID2163 Rev 15).
Technical Context
The LM358PT integrates two independent, internally frequency-compensated op amps optimized for stable operation from a single 3–30 V supply. Its input stage includes PNP transistors enabling common-mode voltage range extending to the negative rail, while the output stage supports 0 V to (VCC – 1.5 V) swing under load.
It delivers 0.6 V/µs slew rate and 0.7–1.1 MHz gain-bandwidth product at 30 V supply, with 70–85 dB common-mode rejection and 65–100 dB supply voltage rejection - making it suitable for precision DC amplification and low-frequency AC signal processing without dual-rail infrastructure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 30 V - enables direct interface with 5 V logic rails and compatibility with wide industrial supply buses. |
| DC Voltage Gain | 100 dB - provides ≥10⁵ open-loop gain for high-accuracy closed-loop gain setting in sensor amplifiers. |
| Unity-Gain Bandwidth | 1.1 MHz - supports stable amplification of signals up to ~100 kHz at moderate closed-loop gains (e.g., ×10). |
| Input Offset Voltage | 2 mV (typ.) - sets baseline DC error floor in precision DC-coupled applications like load cell signal chains. |
| Input Bias Current | 20 nA (typ.) - allows high-impedance source interfacing (e.g., thermistors, photodiodes) without significant loading error. |
| Output Voltage Swing | 0 V to (VCC – 1.5 V) - enables true ground-referenced output in single-supply configurations, critical for ADC driver stages. |
| Common-Mode Input Range | Includes negative rail (GND) - permits direct sensing of signals referenced to system ground without level-shifting circuitry. |
Pinout & Package
LM358PT is supplied in a RoHS-compliant TSSOP-8 (Thin Shrink Small Outline Package, 3.0 × 4.4 mm) with exposed pad option per ST's ECOPACK® standard. This package offers improved thermal performance (RthJA = 120 °C/W) and space efficiency over SO8, suited for compact industrial and consumer PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Amplifier A output node - drives external loads up to 40 mA sink/source; swing limited to 0 V to (VCC – 1.5 V). |
| 2 | Inverting Input A | High-impedance differential input for amplifier A - accepts signals within GND to (VCC – 1.5 V) common-mode range. |
| 3 | Non-inverting Input A | High-impedance differential input for amplifier A - same voltage range and bias current as Pin 2. |
| 4 | VCC– (GND) | Negative supply terminal - tied to system ground in single-supply operation; reference for all internal biasing. |
| 5 | Non-inverting Input B | Independent high-Z input for amplifier B - electrically isolated from Amp A; shares same input specs. |
| 6 | Inverting Input B | Independent high-Z input for amplifier B - identical electrical behavior to Pin 2, no crosstalk with Amp A. |
| 7 | Output B | Amplifier B output node - fully decoupled from Output A; supports simultaneous dual-channel operation. |
| 8 | VCC+ | Positive supply terminal - accepts 3–30 V DC; supply current (1.2 mA typ. at 5 V) is supply-voltage-independent. |
Key Features
| Feature | Design Value |
|---|---|
| Internal Frequency Compensation | Enables stable unity-gain operation without external compensation components - reduces BOM count and layout sensitivity. |
| Rail-to-Rail Input Common-Mode Range | Supports input signals down to GND in single-supply mode - eliminates need for level-shifting networks in sensor front-ends. |
| Low Supply Current per Channel | 0.6 mA typical at 5 V - enables battery-powered or energy-constrained designs (e.g., portable instrumentation, IoT nodes). |
| Temperature-Compensated Input Offset | 7–15 µV/°C drift (A-grade) - maintains DC accuracy across 0–70°C industrial ambient without recalibration. |
| Differential Input Voltage Range | Equal to full supply voltage (±32 V max) - prevents latch-up during input overvoltage events up to rail limits. |
Applications
| Transducer Signal Conditioning | Industrial 4–20 mA Loop Receiver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DT (SO8) | Same electrical specs, but in larger SO8 package (RthJA = 125 °C/W vs. TSSOP-8's 120 °C/W); no exposed pad. | Better suited for prototyping or through-hole-to-SMT transition; less space-constrained layouts. | Select when board area is not constrained and hand-soldering or legacy footprint compatibility is required. |
| LM2904PT (TSSOP-8) | Automotive-qualified (AEC-Q100 Grade 2, -40 to 105°C); identical pinout and DC specs, but tighter offset (1 mV typ.) and higher ESD rating (2 kV HBM). | Required for automotive body electronics, ADAS sensors, or industrial systems needing extended temperature reliability. | Select when operating ambient exceeds 70°C or automotive qualification and enhanced robustness are mandatory. |
Compared with LM358DT, LM358PT saves board area and improves thermal dissipation; compared with LM2904PT, it trades automotive qualification and tighter offset for cost-sensitive commercial-grade operation at 0–70°C.

FAQ
Can LM358PT operate from a 3.3 V supply?
Yes. LM358PT is specified for 3 V to 30 V single-supply operation. At 3.3 V, it maintains functional input common-mode range (0 V to 1.8 V), 0.3 V/µs slew rate, and usable 100 dB gain - though output swing reduces to ~0 V to 1.8 V and bandwidth narrows slightly. Verified per Table 2 (Operating Conditions) and Figure 11 (Input Voltage Range) in DocID2163 Rev 15.
Does LM358PT have rail-to-rail output capability?
No - LM358PT provides output swing from 0 V to (VCC – 1.5 V) under load, not true rail-to-rail. For example, at 5 V supply, output reaches ~3.5 V maximum. This limitation stems from its bipolar output stage design. It does support rail-to-rail *input* common-mode range, including GND, which is confirmed in Section 4 (Electrical Characteristics) and Figure 11 of the datasheet.
What is the maximum capacitive load LM358PT can drive stably?
LM358PT remains stable driving up to 100 pF directly (per Figure 18: Phase Margin vs. Capacitive Load). Beyond that, phase margin degrades - at 290 pF, phase margin drops below 20° at 25°C. For loads >100 pF, ST recommends isolating with a series resistor (≥100 Ω) or using a unity-gain buffer stage. This behavior is documented in Figure 18 and Note (3) of Table 3.
Is LM358PT pin-compatible with LM2904PT?
Yes - LM358PT and LM2904PT share identical TSSOP-8 pinout, electrical specifications (except temperature grade and offset), and functional behavior. Both follow the standard dual op amp pin mapping (Output A, In– A, In+ A, GND, In+ B, In– B, Output B, VCC+). This compatibility is confirmed in ST's ordering tables (Section 8) and package drawings (Figure 32) of DocID2163 Rev 15.
