Product details
Overview
LM358AWPT from STMicroelectronics is a low-power dual operational amplifier in TSSOP8 package, designed for single-supply operation from 3 V to 30 V. It delivers 100 dB large-signal voltage gain, 1.1 MHz unity-gain bandwidth, and rail-to-rail output swing down to 0 V (VCC−1.5 V), with 2 mV input offset voltage and 20 nA input bias current at +25 °C. It is widely used in transducer signal conditioning and DC gain blocks within industrial sensor interfaces.
For engineers reviewing the LM358AWPT datasheet, LM358AWPT pinout, LM358AWPT application, or LM358AWPT equivalent, key selection criteria include single-supply compatibility, ground-sensing input range, output drive capability (±40 mA), thermal resistance (120 °C/W), and automotive-grade qualification status per AEC-Q100.
Technical Context
The LM358AWPT integrates two independent high-gain op-amps with internal frequency compensation, enabling stable unity-gain operation without external components. Its PNP input stage supports input common-mode voltage down to ground and differential input range equal to full supply voltage.
It features temperature-compensated input offset voltage (2 mV max) and bias current (20 nA typ), along with ESD protection rated at 2 kV HBM. The output stage provides asymmetrical sourcing (60 mA) and sinking (20 mA) capability under VCC = +15 V, with low-level output voltage as low as 20 mV at 10 kΩ load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 30 V - enables direct interface with 5 V logic systems and wide industrial supply rails. |
| Large-Signal Voltage Gain | 100 dB - ensures high-precision amplification of low-level sensor signals with minimal error. |
| Unity-Gain Bandwidth | 1.1 MHz - supports audio-frequency and medium-speed control loop applications. |
| Input Offset Voltage | 2 mV max - limits DC error in precision DC-coupled amplifiers and instrumentation front-ends. |
| Input Bias Current | 20 nA typ at +25 °C - minimizes voltage drop across high-impedance source networks (e.g., thermistors). |
| Output Voltage Swing | 0 V to (VCC − 1.5 V) - allows ground-referenced output in single-supply configurations. |
| ESD Protection | 2 kV HBM - enhances robustness during PCB handling and system integration. |
Pinout & Package

|---|---|---|
| 1 | Output 1 | Amplifier 1 output node; capable of sourcing up to 60 mA and sinking 20 mA. |
| 2 | Inverting Input 1 | High-impedance inverting terminal of first op-amp; accepts input down to −0.3 V relative to ground. |
| 3 | Non-inverting Input 1 | High-impedance non-inverting terminal; common-mode range includes ground and extends to VCC − 1.5 V. |
| 4 | VCC− / Ground | Power reference for single-supply operation; all inputs and outputs referenced to this node. |
| 5 | Non-inverting Input 2 | Second op-amp's non-inverting input; electrically isolated but shares same substrate and thermal path. |
| 6 | Inverting Input 2 | Second op-amp's inverting input; supports identical common-mode and overvoltage tolerance as Pin 2. |
| 7 | Output 2 | Amplifier 2 output; matches Output 1 in drive strength, slew rate (0.6 V/µs typ), and voltage swing. |
| 8 | VCC+ | Positive supply rail; supports up to +30 V; internal protection limits dissipation during short-circuit events. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Operates from 3 V to 30 V with input common-mode range including ground and output swing to 0 V. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DT | SO8 package, commercial temperature range (0 °C to +70 °C), no AEC-Q100 qualification. | Suitable for cost-sensitive consumer electronics; lacks automotive reliability testing and extended thermal margin. | Select when automotive qualification and −40 °C operation are not required; lower unit cost and broader distributor availability. |
| TSV912IDT | Rail-to-rail input/output, 8 MHz GBW, 1.1 V/µs slew rate, 60 µA supply current per amplifier. | Better AC performance and input flexibility, but higher supply current and narrower common-mode range near VCC. | Choose for higher-speed signal paths (e.g., active filters >100 kHz); avoid where ground-sensing input or ultra-low ICC is mandatory. |
Compared with LM358DT, LM358AWPT adds automotive qualification and extended temperature support; versus TSV912IDT, it trades bandwidth and rail-to-rail input for lower power, ground-compatible inputs, and proven industrial robustness.

FAQ
Is LM358AWPT pin-compatible with standard LM358 variants?
Yes, LM358AWPT uses the industry-standard TSSOP8 pinout matching LM358xPT variants. Pin 1 is Output 1, Pin 2 is Inverting Input 1, Pin 3 is Non-inverting Input 1, Pin 4 is VCC−, Pin 5 is Non-inverting Input 2, Pin 6 is Inverting Input 2, Pin 7 is Output 2, and Pin 8 is VCC+. No board redesign is needed when upgrading from non-automotive TSSOP8 versions.
What is the maximum capacitive load the LM358AWPT can drive stably?
LM358AWPT maintains phase margin ≥45° with up to 100 pF capacitive load at unity gain (VCC = +15 V, Vicm = +7.5 V), as confirmed in Figure 17 of the datasheet. For loads exceeding 100 pF, external isolation resistor (≥100 Ω) is recommended between output and capacitance to prevent oscillation.
Does LM358AWPT support true rail-to-rail input?
No. LM358AWPT features input common-mode voltage range extending to ground (0 V) and up to VCC − 1.5 V, but does not support rail-to-rail input. Its PNP input stage allows ground-sensing operation-critical for single-supply sensor interfaces-but cannot accept inputs within ~1.5 V of VCC without parameter degradation.
Can LM358AWPT be used in comparator applications?
Yes, though not optimized for speed. With open-loop gain >100 dB and propagation delay ~1.5 µs (for 100 mV overdrive), it functions reliably as a slow comparator in non-critical threshold-detection circuits. However, dedicated comparators (e.g., TS882) offer faster response, built-in hysteresis, and lower input offset for precision applications.
