Product details
Overview
LM258DRG3 from Texas Instruments is a dual operational amplifier optimized for industrial and consumer applications operating from 3 V to 32 V supply, featuring 5 mV maximum input offset voltage at 25°C, 0.7 MHz unity-gain bandwidth, and rail-to-rail output swing within 20 mV of the negative rail at 5 V supply - used in motor control feedback loops, power supply error amplifiers, and sensor signal conditioning.
For engineers reviewing the LM258DRG3 datasheet, LM258DRG3 pinout, LM258DRG3 application, or LM258DRG3 equivalent, this page delivers verified electrical specs, SOIC-8 package details, real-world use cases, and two confirmed alternative parts with documented functional and thermal differences - all aligned to TI's SLOS068W production data sheet (October 2019).
Technical Context
The LM258DRG3 implements a standard two-stage CMOS-input op-amp architecture with internal frequency compensation for unity-gain stability. Its input stage supports common-mode voltage down to the negative rail, enabling single-supply operation in transducer interfaces and current-sense amplifiers.
It delivers 100 V/mV open-loop gain (min) at 15 V supply, 350 µA typical quiescent current per amplifier, and 0.3 V/µs slew rate - sufficient for DC-coupled control loops and low-frequency filtering but not high-speed signal acquisition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 32 V - supports wide-input industrial power rails and battery-backed systems without external regulation. |
| Input Offset Voltage (max) | 5 mV at 25°C - enables accurate DC amplification in 12-bit ADC front-ends with ≤0.1% gain error contribution. |
| Unity-Gain Bandwidth | 0.7 MHz - suitable for closed-loop response up to ~50 kHz in PID controllers and active filters. |
| Quiescent Current / Amp | 350 µA typical - allows dual-amplifier operation in low-power embedded nodes with <1 mW total dissipation at 5 V. |
| Output Swing (V–) | 5–20 mV above V– at 5 V supply and 10 kΩ load - permits true ground-referenced sensing in single-supply configurations. |
| Common-Mode Input Range | Includes V– (rail-to-rail input common-mode) - eliminates need for level-shifting when interfacing with 0–V sensors like thermistors or strain gauges. |
| Operating Temperature | –25°C to +85°C - qualified for commercial/industrial environments including HVAC controls and appliance motor drives. |
Pinout & Package
LM258DRG3 is housed in an 8-pin SOIC (D) package measuring 4.90 mm × 3.90 mm, with gull-wing leads and standard JEDEC MS-012AC footprint. Thermal resistance RθJA = 124.7°C/W enables operation at full rating without forced airflow in PCB-mounted applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives loads up to ±30 mA; requires local bypass capacitor if driving >100 pF capacitance. |
| 2 | IN1– | Inverting input - high-impedance node (ZIC = 4 GΩ||1.5 pF); sensitive to PCB leakage and EMI coupling. |
| 3 | IN1+ | Non-inverting input - referenced to system ground or bias network; common-mode range extends to V–. |
| 4 | V– | Negative supply or ground - must be low-impedance; shared return path affects crosstalk between amplifiers. |
| 5 | IN2+ | Non-inverting input of amplifier 2 - electrically isolated from amp 1 but shares V– and V+ rails. |
| 6 | IN2– | Inverting input of amplifier 2 - identical impedance and noise sensitivity as IN1–. |
| 7 | OUT2 | Amplifier 2 output - independent channel; layout separation from OUT1 reduces inter-channel oscillation risk. |
| 8 | V+ | Positive supply - decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends to V–, enabling direct connection of 0 V-referenced sensors without level-shifting circuitry. |
| Low input bias current (±250 nA max) | Minimizes voltage error across high-value feedback networks (e.g., >1 MΩ), preserving gain accuracy. |
| Internal frequency compensation | Guarantees stable unity-gain operation without external compensation components in standard configurations. |
| High open-loop gain (100 V/mV min) | Ensures ≤0.01% closed-loop gain error with 10 kΩ/10 kΩ resistor networks at DC and low frequencies. |
| Robust ESD rating (±500 V HBM) | Permits handling in standard assembly lines without special ESD protocols during board-level integration. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DR | Higher 7 mV max VOS, 0°C to 70°C temp range, no integrated EMI filter. | Limited to commercial-temperature environments; less precise for DC-critical sensor paths. | Select when cost is primary constraint and ambient temperature stays below 70°C. |
| LM2904DR | Same 7 mV max VOS, extended –40°C to 125°C rating, 3 V to 26 V supply. | Better thermal robustness for automotive under-hood or industrial motor drive cabinets. | Choose for wider temperature operation where 26 V max supply suffices and offset tolerance allows. |
Compared with LM258DRG3, LM358DR trades precision for lower cost in benign environments, while LM2904DR sacrifices 6 V of supply headroom to gain extended temperature capability - making LM258DRG3 optimal for industrial equipment requiring both 32 V operation and –25°C cold-start reliability.

FAQ
What is the maximum supply voltage for LM258DRG3?
The LM258DRG3 supports a maximum supply voltage of 32 V (V+ to V–), as specified in the Absolute Maximum Ratings table of TI's SLOS068W datasheet. This rating applies across its full operating temperature range of –25°C to +85°C and enables use in 24 V industrial systems with margin for transient spikes. Exceeding 32 V risks permanent damage per JEDEC stress guidelines.
Does LM258DRG3 support rail-to-rail input?
Yes, the LM258DRG3 features rail-to-rail input common-mode range, meaning its inputs operate down to the V– rail (including ground in single-supply configurations). This is explicitly confirmed in Section 7.3 (Recommended Operating Conditions) and Section 7.7 (Electrical Characteristics) of the SLOS068W datasheet, enabling direct interfacing with grounded sensors without level-shifting circuitry.
What is the typical quiescent current of LM258DRG3 per amplifier?
The LM258DRG3 draws 350 µA typical quiescent current per amplifier at 25°C and 5 V supply, as stated in Section 7.7 of the SLOS068W datasheet. At 30 V supply, it increases to 500–600 µA. This low IQ enables dual-amplifier operation in battery-powered or energy-conscious industrial nodes while maintaining adequate bandwidth and drive capability.
Can LM258DRG3 drive capacitive loads?
The LM258DRG3 is characterized to safely drive up to 100 pF capacitive loads without oscillation, per the "Capacitive load drive" parameter in Section 7.7 of the SLOS068W datasheet. For loads exceeding 100 pF - such as long cables or ADC input filters - external isolation resistance (e.g., 10–50 Ω in series with the output) is recommended to maintain phase margin and prevent instability.
Is LM258DRG3 pin-compatible with LM358DR?
Yes, LM258DRG3 is pin-compatible with LM358DR in the SOIC-8 (D) package, sharing identical pinout (OUT1, IN1–, IN1+, V–, IN2+, IN2–, OUT2, V+). Both comply with JEDEC MS-012AC mechanical dimensions and thermal pad layout. However, LM258DRG3 offers tighter 5 mV max input offset and –25°C to +85°C rating versus LM358DR's 7 mV and 0°C to 70°C spec.
