Product details
Overview
LM258DR 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 LM258DR datasheet, LM258DR pinout, LM258DR application, or LM258DR 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.
Technical Context
The LM258DR implements two independent high-voltage op amps in a single SOIC-8 package, each with internal frequency compensation for unity-gain stability and common-mode input range extending to ground - enabling direct interfacing with low-side current-sense resistors and single-supply sensor outputs.
It operates across –25°C to +85°C ambient temperature, supports differential input voltages up to ±32 V, and delivers 350 µA typical quiescent current per amplifier - balancing precision, power efficiency, and ruggedness for cost-sensitive embedded systems without integrated EMI filtering.
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 - sets baseline DC accuracy for closed-loop control and analog front-end gain stages. |
| Unity-Gain Bandwidth | 0.7 MHz - limits usable small-signal bandwidth for audio preamps, active filters, and moderate-speed feedback paths. |
| Slew Rate | 0.3 V/µs - constrains large-signal transient response; suitable for <10 kHz signal conditioning but not fast pulse shaping. |
| Common-Mode Input Range | Includes ground (V–) - enables direct sensing of signals referenced to system ground, e.g., shunt-based current measurement. |
| Output Swing (Negative Rail) | 5–20 mV above V– at 5 V supply - allows near-ground output capability critical for single-supply transimpedance amplifiers. |
| Quiescent Current / Amp | 350 µA typical - enables low-power operation in always-on monitoring circuits without thermal derating concerns. |
Pinout & Package
LM258DR is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package measuring 4.90 mm × 3.90 mm, with standard JEDEC MS-012AC footprint and 1.27 mm lead pitch - compatible with automated SMT assembly and IPC-7351B land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives loads up to ±30 mA; requires external compensation if driving >100 pF capacitive loads. |
| 2 | IN1– | Inverting input - high-impedance node (10 MΩ || 0.1 pF); sensitive to PCB leakage and EMI coupling. |
| 3 | IN1+ | Non-inverting input - same impedance as IN1–; used for reference biasing or sensor excitation return. |
| 4 | V– | Negative supply or ground - must be low-impedance; shared return path for both amplifiers and load currents. |
| 5 | IN2+ | Non-inverting input (Amp 2) - electrically isolated from Amp 1; supports dual-channel signal processing on one die. |
| 6 | IN2– | Inverting input (Amp 2) - identical electrical characteristics to IN1–; no crosstalk specification provided. |
| 7 | OUT2 | Amplifier 2 output - independent sourcing/sinking capability; shares V+ and V– rails with OUT1. |
| 8 | V+ | Positive supply - accepts up to 32 V; bypass capacitor (0.1 µF ceramic) required within 5 mm of pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 3 V to 32 V operation - eliminates need for dedicated LDOs in multi-rail industrial systems. |
| Ground-Sensing Inputs | Common-mode range includes V– - enables direct interface with 0 V-referenced sensors (e.g., thermistors, RTDs). |
| Rail-to-Rail Output (Low Side) | Swings within 20 mV of V– at 5 V - preserves dynamic range in single-supply configurations with grounded references. |
| Dual Amplifier Integration | Two matched op amps in one SOIC-8 - reduces board area and component count versus discrete solutions. |
| Stable Unity-Gain Operation | Internally compensated - no external components needed for basic buffer or gain-of-2 configurations. |
Applications
| Motor Control Feedback | Power Supply Error Amplifier |
|---|---|
|

IC Role / Device Role / Timing Role: First-stage instrumentation amplifier (Amp 1) and second-stage filter/buffer (Amp 2). Use Value: 5 mV max VOS avoids zero-point calibration drift; 32 V max supply accommodates 24 V field bus interfaces. |
Use Scenario: Providing analog input protection, scaling, and isolation interface in PLC analog input cards. IC Role / Device Role / Timing Role: Signal conditioner for 4–20 mA loop receivers and voltage input multiplexers. Use Value: Dual configuration allows simultaneous handling of two channels; SOIC-8 footprint fits dense I/O layouts. |
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 max input offset (7 mV), wider temp range (0°C to 70°C), same SOIC-8 package and pinout. | Lower precision; suited for non-critical signal paths where cost is primary constraint. | Select LM358DR only when VOS >5 mV is acceptable and ambient stays within commercial temperature range. |
| LM2904DR | Extended temp range (–40°C to 125°C), same 7 mV VOS, 3 V–26 V supply, no EMI filter. | Required for automotive under-hood or industrial high-temp environments; lower max supply voltage. | Choose LM2904DR when operating beyond 85°C or requiring automotive-grade qualification - verify supply headroom. |
Compared with LM258DR, LM358DR trades precision for broader commercial availability, while LM2904DR prioritizes thermal robustness over input accuracy - making LM258DR optimal for industrial applications needing balanced performance at –25°C to 85°C.

FAQ
What is the maximum operating temperature for the LM258DR?
The LM258DR is rated for operation from –25°C to +85°C ambient temperature. This range is specified in the Recommended Operating Conditions table of the official TI datasheet (SLOS068W, Section 7.3). Exceeding +85°C may cause parametric shift or reliability degradation; for higher-temperature environments, consider LM2904DR instead. The LM258DR itself does not support operation beyond +85°C.
Does the LM258DR include an integrated EMI filter?
No, the LM258DR does not include an integrated EMI filter. According to TI's Device Comparison Table (Section 5 of SLOS068W), only the B-version devices (e.g., LM358B, LM2904B) list "Yes" under Integrated EMI Filter. The LM258DR is explicitly marked "No", confirming it lacks this feature - external RC filtering or layout best practices are required for noisy environments.
Can the LM258DR drive a 100-pF capacitive load directly?
Yes, the LM258DR can drive up to 100 pF capacitive load without external compensation, as confirmed by its Electrical Characteristics table (Section 7.7, CLOAD parameter). However, stability margins degrade near this limit - TI recommends adding a 10 Ω series resistor between the output and load for improved phase margin when driving >50 pF. Larger loads require isolation or active compensation.
Is the LM258DR pin-compatible with the LM358DR?
Yes, the LM258DR is pin-compatible with the LM358DR in SOIC-8 packaging. Both share identical pin functions (OUT1, IN1–, IN1+, V–, IN2+, IN2–, OUT2, V+) and mechanical footprint per TI's Device Information table (Section 4). No PCB redesign is needed for substitution, though design validation is required due to differences in input offset voltage (5 mV vs. 7 mV) and temperature range (–25°C to 85°C vs. 0°C to 70°C).
What is the typical quiescent current per amplifier in the LM258DR?
The LM258DR draws 350 µA typical quiescent current per amplifier at 25°C and 5 V supply, as specified in Section 7.7 (Electrical Characteristics: LM358, LM358A) of the TI datasheet. At 30 V supply, quiescent current rises to 500–1000 µA depending on temperature - this increase must be accounted for in high-voltage, low-power designs.
