Product details
Overview
LM258APT from STMicroelectronics is a low-power dual operational amplifier designed for single-supply operation across 3 V to 30 V, featuring 1.1 MHz unity-gain bandwidth, 100 dB large-signal voltage gain, and rail-to-rail output swing down to 0 V (with VCC+ − 1.5 V maximum high-level output). It operates over −40 °C to +105 °C and is commonly used in transducer signal conditioning, DC gain blocks, and industrial sensor interfaces.
For engineers reviewing the LM258APT datasheet, LM258APT pinout, LM258APT application, or LM258APT equivalent, this page delivers verified electrical specs, TSSOP8 package details, real-world use cases in single-supply systems, and validated alternative options with documented functional differences.
Technical Context
This dual op-amp integrates two independent, internally frequency-compensated amplifiers optimized for stable operation from a single supply. Its input stage uses PNP transistors enabling common-mode input 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 typical slew rate and 0.7–1.1 MHz gain-bandwidth product at VCC+ = 30 V, with 20 nA max input bias current and 2 mV max input offset voltage (LM258A grade), making it suitable for precision DC-coupled amplification where power efficiency and rail-compatible I/O are required.
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 wide industrial supply buses without regulation. |
| Unity-Gain Bandwidth | 1.1 MHz - supports audio-frequency amplification and medium-speed sensor signal conditioning. |
| Large-Signal Voltage Gain | 100 dB - ensures <10 µV output error for 1 V input signals, critical for precision DC gain stages. |
| Input Offset Voltage (max) | 3 mV (LM258A grade) - defines worst-case DC error in differential sensing applications like bridge amplifiers. |
| Input Bias Current (max) | 50 nA - 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. |
| Operating Temperature | −40 °C to +105 °C - qualified for industrial and extended commercial environments, not automotive. |
Pinout & Package
TSSOP8 package: 3 mm × 4.4 mm, 0.65 mm pitch, thin shrink small outline package with exposed pad (not electrically connected by default).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Amplifier A) | Accepts feedback network connection; referenced to non-inverting input for closed-loop gain control. |
| 2 | Non-inverting input (Amplifier A) | DC reference or sensor signal input; common-mode range includes ground for single-supply use. |
| 3 | Output (Amplifier A) | Delivers amplified signal; capable of sourcing up to 40 mA and sinking 20 mA into resistive loads. |
| 4 | GND | Power and signal reference node; must be low-impedance return path for both amplifiers and load currents. |
| 5 | Non-inverting input (Amplifier B) | Independent second channel input; identical electrical characteristics to Pin 2. |
| 6 | Inverting input (Amplifier B) | Second channel feedback node; supports separate gain configuration from Amplifier A. |
| 7 | Output (Amplifier B) | Second independent output; shares same drive capability and voltage swing limits as Pin 3. |
| 8 | VCC+ | Positive supply rail; supplies both amplifiers; current draw is 0.7–1.2 mA total at 5 V, independent of load. |
Key Features
| Feature | Design Value |
|---|---|
| Internally compensated | Eliminates need for external compensation components, reducing BOM count and layout sensitivity. |
| Rail-to-rail input common-mode range | Includes negative rail (GND), enabling direct ground-referenced sensor inputs without level-shifting circuitry. |
| Low quiescent current per channel | ≤600 µA per amplifier at 5 V - supports battery-powered instrumentation and always-on monitoring nodes. |
| Temperature-compensated parameters | Input offset voltage drift ≤15 µV/°C and bias current drift ≤200 pA/°C ensure stable DC performance over temperature. |
| Differential input voltage range | Equal to full supply voltage (±32 V absolute max) - prevents internal junction breakdown during input overvoltage events. |
Applications
| Transducer Signal Conditioning | Industrial DC Gain Block |
|---|---|
|
Use Scenario: Amplifying low-level mV outputs from pressure sensors or load cells in factory automation PLC modules. IC Role / Device Role / Timing Role: Dual-channel DC-coupled amplifier providing fixed gain (e.g., ×100) and buffer isolation between sensor and ADC input. Use Value: Input common-mode range to GND and 2 mV max offset enable accurate zero-point calibration without trimming resistors. |
Use Scenario: Scaling 0–10 V industrial control signals to match 3.3 V ADC full-scale range in motor drive feedback circuits. IC Role / Device Role / Timing Role: Non-inverting amplifier with precise resistor ratio gain setting and rail-compatible output swing. Use Value: 100 dB open-loop gain ensures <0.1% gain error with standard 1% metal-film resistors, reducing calibration overhead. |
| Single-Supply Audio Preamp | Comparator Interface Circuit |
|
Use Scenario: Boosting microphone signals in portable diagnostic equipment powered by a single 5 V USB supply. IC Role / Device Role / Timing Role: AC-coupled inverting amplifier with adjustable gain and DC-blocking capacitors on both inputs and output. Use Value: 1.1 MHz bandwidth supports 20 kHz audio passband; low THD (0.02%) preserves signal fidelity in analog front-ends. |
Use Scenario: Converting slow-moving analog thresholds (e.g., temperature trip points) into clean digital logic levels for microcontroller GPIO. IC Role / Device Role / Timing Role: Open-loop comparator with hysteresis added via feedback resistor, leveraging rail-to-rail output swing. Use Value: Output swing to 0 V and ≥3.5 V at 5 V supply ensures reliable TTL/CMOS logic-level compatibility without pull-up resistors. |
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 |
|---|---|---|---|
| LM2904DT | Automotive-qualified (AEC-Q100), wider temp range (−40 °C to +125 °C), identical pinout and electrical specs except higher ESD rating (2 kV HBM). | Required for automotive ECUs or safety-critical industrial controllers needing extended qualification. | Select when AEC-Q100 compliance or 125 °C operation is mandatory; otherwise LM258APT offers cost advantage for commercial/industrial use. |
| TLV2372IDR | Rail-to-rail input/output, lower supply current (550 µA/channel), but reduced GBW (3 MHz) and narrower supply range (2.7–16 V). | Suitable for ultra-low-power battery devices where full rail I/O and sub-1 µA shutdown are needed. | Choose only if rail-to-rail I/O is essential and supply voltage never exceeds 16 V; LM258APT better supports 24 V industrial rails. |
Compared with LM2904DT, LM258APT trades automotive qualification for lower unit cost in non-automotive settings; versus TLV2372IDR, it sacrifices rail-to-rail output flexibility to maintain 30 V supply tolerance and proven stability in legacy 5 V/12 V designs.

FAQ
Is LM258APT pin-compatible with LM358 series devices?
Yes - LM258APT uses the standard TSSOP8 pinout matching LM358PT, LM358APT, and LM2904PT. All share identical pin functions (GND at Pin 4, VCC+ at Pin 8, dual op-amp topology), enabling drop-in replacement in existing layouts where temperature range and qualification align.
What is the maximum capacitive load LM258APT can drive without instability?
LM258APT maintains phase margin >30° with up to 290 pF capacitive load at VCC = 15 V and Vicm = 7.5 V, per Figure 18 in the datasheet. For loads >100 pF, add a 10–100 Ω series resistor between output and capacitor to isolate reactive feedback and preserve stability.
Does LM258APT support dual-supply operation?
Yes - though optimized for single supply, LM258APT operates with split rails (e.g., ±15 V) within its absolute maximum ratings (±16 V or 32 V total). Input common-mode range extends to VCC−, and output swing remains symmetric about mid-rail when biased appropriately.
Can LM258APT be used as a comparator?
Yes - its open-loop configuration functions as a comparator, but with limited speed (slew rate 0.6 V/µs) and no internal hysteresis. For reliable switching, add external positive feedback; avoid sustained differential input voltages beyond ±32 V or output short-circuits to VCC+ above 15 V to prevent thermal damage.
