Product details
Overview
LM258ADT 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 input common-mode range extending to the negative rail. It delivers 2 mV typical input offset voltage, 20 nA input bias current, and operates over –40 °C to +105 °C - widely deployed in industrial sensor signal conditioning and 5 V logic-compatible analog front-ends.
For engineers reviewing the LM258ADT datasheet, LM258ADT pinout, LM258ADT application, or LM258ADT equivalent, this page provides verified technical context, SO8 package mapping, real-world use cases in transducer amplification and DC gain blocks, and validated alternatives for temperature-stable dual op-amp selection.
Technical Context
This dual op-amp integrates two independent, internally frequency-compensated high-gain amplifiers optimized for single-supply systems. Its input stage uses PNP transistors enabling input common-mode voltage down to ground (VCC–), while output swing reaches 0 V to (VCC+ – 1.5 V) under load.
It exhibits temperature-compensated parameters: 7–15 µV/°C input offset drift and stable 0.3–0.6 V/µs slew rate across supply voltages. Supply current remains essentially constant (0.7–1.2 mA total at 5 V) regardless of VCC magnitude, supporting energy-constrained designs.
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 higher-voltage industrial supplies without level-shifting. |
| Unity-Gain Bandwidth | 1.1 MHz - supports audio-frequency amplification and medium-speed sensor signal processing (e.g., thermocouple, strain gauge). |
| Input Offset Voltage | 1 mV (typ), 3 mV (max) at 25 °C - ensures <0.1% DC error in precision gain stages up to ×100. |
| Input Bias Current | 20 nA (typ) - minimizes voltage error across high-impedance sources like photodiodes or pH electrodes. |
| Common-Mode Input Range | Includes VCC– (ground) - allows direct sensing of signals referenced to system ground in single-supply configurations. |
| Output Voltage Swing | 0 V to (VCC+ – 1.5 V) - delivers usable dynamic range near ground and rail, critical for ADC driver stages. |
| Operating Temperature | –40 °C to +105 °C - qualified for industrial control, motor drives, and automotive cabin electronics. |
Pinout & Package
LM258ADT is supplied in an SO8 (Small Outline 8-pin) package per JEDEC MS-012, with standard 1.27 mm pitch and gull-wing leads. Thermal resistance is 125 °C/W (junction-to-ambient), suitable for moderate-power analog circuits on FR-4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Amplifier A output - capable of sourcing 20–60 mA and sinking 10–20 mA; swings 0 V to (VCC+ – 1.5 V). |
| 2 | Inverting Input A | High-impedance node (20 nA bias) - used for feedback networks and inverting configurations; accepts inputs down to VCC–. |
| 3 | Non-inverting Input A | High-impedance node - enables DC-coupled sensor interfaces with ground-referenced sources. |
| 4 | VCC– (GND) | Power reference for single-supply operation - all inputs and outputs referenced to this pin. |
| 5 | Non-inverting Input B | Independent second amplifier input - identical electrical behavior to Pin 3; supports dual-channel signal paths. |
| 6 | Inverting Input B | Second amplifier inverting input - used for differential amplification or independent gain stages. |
| 7 | Output B | Amplifier B output - electrically identical to Pin 1; enables compact dual-function circuits without external duplication. |
| 8 | VCC+ | Positive supply rail - accepts 3–30 V; supply current draw is independent of voltage magnitude (0.7–1.2 mA total). |
Key Features
| Feature | Design Value |
|---|---|
| Internal frequency compensation | Enables stable unity-gain operation without external components - reduces BOM count and layout sensitivity. |
| Rail-to-rail input common-mode range | Accepts signals from VCC– (ground) to (VCC+ – 1.5 V) - eliminates need for input biasing in single-supply transducer interfaces. |
| Low input offset voltage drift | 7–15 µV/°C - maintains DC accuracy across industrial temperature ranges without recalibration. |
| Supply current independence | 0.7–1.2 mA total (2 channels) across 5–30 V supply - simplifies power budgeting in variable-voltage systems. |
| Enhanced ESD robustness | 300 V HBM - improves manufacturing yield and field reliability in handling-sensitive industrial environments. |

IC Role / Device Role / Timing Role: AC-coupled inverting amplifier with adjustable gain and high-pass filtering to suppress DC bias and hum. Use Value: Rail-to-rail input allows direct coupling to electret mic bias; 0.3 V/µs slew rate supports 20 kHz audio fidelity without distortion. |
Use Scenario: Filtering current-sense amplifier outputs in BLDC motor drivers before PID controller input. IC Role / Device Role / Timing Role: Second-order active low-pass filter (Sallen-Key) rejecting PWM switching noise above 20 kHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2904DT | Automotive-qualified (AEC-Q100), wider temp range (–40 °C to +125 °C); otherwise identical electrical specs and pinout. | Required for under-hood or chassis-mounted systems where extended temperature and qualification compliance are mandatory. | Select LM2904DT when automotive qualification, enhanced ESD (2 kV HBM), or 125 °C operation is required - drop-in replacement otherwise. |
| TL072CDT | Higher slew rate (13 V/µs), lower noise (18 nV/√Hz), JFET input (50 pA bias), but requires dual supply (±12 V typical) and lacks rail-to-rail input. | Suitable for high-fidelity audio or wide-dynamic-range instrumentation where noise and speed outweigh single-supply convenience. | Choose TL072CDT only when dual supply is available and low-noise, high-speed performance justifies redesign - not pin-compatible. |
Compared with LM258ADT, LM2904DT adds automotive qualification and extended temperature margin with no trade-offs in cost or footprint, while TL072CDT trades single-supply capability for superior AC performance - making LM258ADT optimal for cost-sensitive, ground-referenced industrial signal chains.

FAQ
Can LM258ADT operate from a 3.3 V supply?
Yes. LM258ADT is fully specified from 3 V to 30 V. At 3.3 V, it maintains rail-to-rail input operation (down to ground) and delivers usable output swing (0 V to ~1.8 V). Input offset voltage increases slightly (to ~3 mV max), but remains within specification for most low-gain sensor interfaces.
Is LM258ADT pin-compatible with LM358DT?
Yes - both are SO8-packaged dual op-amps with identical pinout (Outputs A/B, Inverting/Non-inverting Inputs A/B, VCC+, GND). However, LM258ADT is rated for –40 °C to +105 °C, while LM358DT is limited to 0 °C to +70 °C; electrical specs (e.g., offset, drift) also differ per grade.
Does LM258ADT require external compensation capacitors?
No. LM258ADT features internal frequency compensation optimized for unity-gain stability. No external capacitor is needed for stable operation in inverting, non-inverting, or voltage-follower configurations - reducing component count and board space.
What is the maximum capacitive load LM258ADT can drive directly?
LM258ADT can safely drive up to 100 pF without instability, as confirmed by phase margin testing. For loads >100 pF (e.g., long cables or ADC input capacitance), a series isolation resistor (10–100 Ω) between output and load is recommended to maintain ≥45° phase margin.
