Product details
Overview
LM258DRG4 from Texas Instruments is a dual operational amplifier optimized for industrial temperature range (–25°C to +85°C), featuring 3 V to 32 V supply operation, 5 mV maximum input offset voltage at 25°C, 350 µA typical quiescent current per amplifier, and rail-to-rail output swing capability near the negative rail-enabling precision signal conditioning in motor control feedback loops and power supply monitoring circuits.
For engineers reviewing the LM258DRG4 datasheet, LM258DRG4 pinout, LM258DRG4 application, or LM258DRG4 equivalent, this page delivers verified electrical specifications, SOIC-8 package mapping, functional pin roles, real-world use cases in embedded power systems, and two validated alternative parts with documented technical and application-level differences.
Technical Context
The LM258DRG4 implements a standard voltage-feedback op amp architecture with high-input impedance (4 GΩ common-mode, 10 MΩ differential), unity-gain stable design, and internal compensation enabling reliable operation in closed-loop configurations such as transimpedance amplifiers and active filters. Its input stage supports common-mode voltages down to the negative rail, allowing direct sensing of low-side current shunts.
It delivers 0.7 MHz gain-bandwidth product and 0.3 V/µs slew rate under 5 V to 30 V supply conditions, with open-loop gain ≥25 V/mV and CMRR ≥65 dB-making it suitable for DC-coupled instrumentation and analog front-end stages where moderate speed and robust DC accuracy are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 32 V - supports single-supply industrial systems without external level-shifting. |
| Input Offset Voltage (max) | 5 mV at 25°C - enables accurate DC amplification in sensor interfaces with <1% error at 500 mV input. |
| Quiescent Current (typ) | 350 µA per amplifier - allows dual-channel operation in battery-backed or energy-constrained modules. |
| Gain-Bandwidth Product | 0.7 MHz - sufficient for anti-aliasing filtering up to ~100 kHz and closed-loop gain ≤100. |
| Slew Rate | 0.3 V/µs - limits full-power bandwidth to ~48 kHz at 10 V output swing, appropriate for slow-varying control signals. |
| Output Swing (neg. rail) | 5–20 mV above V− at 5 V supply - permits true single-supply operation with ground-referenced inputs. |
| Common-Mode Input Range | Includes V− (rail-to-rail input) - eliminates need for biasing resistors when measuring current through low-side shunts. |
Pinout & Package
LM258DRG4 is packaged in an 8-pin SOIC (Small Outline Integrated Circuit) with body dimensions 4.90 mm × 3.90 mm and standard JEDEC MS-012AC footprint. The device uses industry-standard pin numbering and thermal pad layout compatible with automated assembly processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Output of first amplifier - drives loads up to ±30 mA; rail-to-rail swing improves dynamic range in single-supply designs. |
| 2 | IN1− | Inverting input of first amplifier - high-impedance node (≥4 GΩ) minimizes loading on preceding stages. |
| 3 | IN1+ | Non-inverting input of first amplifier - accepts common-mode signals down to V−, enabling ground-sensing applications. |
| 4 | V− | Negative supply or ground reference - serves as return path for both amplifiers and bias network. |
| 5 | IN2+ | Non-inverting input of second amplifier - electrically isolated from Channel 1; shares same V− and V+ rails. |
| 6 | IN2− | Inverting input of second amplifier - matched input characteristics to Pin 2 ensure consistent channel performance. |
| 7 | OUT2 | Output of second amplifier - identical drive capability and output swing behavior as OUT1. |
| 8 | V+ | Positive supply rail - accepts up to 32 V; internal ESD protection rated to ±500 V HBM ensures robustness in factory handling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input (V− included) | Enables direct connection to low-side current sense resistors without external bias networks. |
| Single-supply operation support | Validated across 3 V to 32 V range - simplifies power architecture in PLC I/O modules and HVAC controllers. |
| High common-mode rejection (≥65 dB) | Rejects noise coupling from shared supply rails in multi-amplifier signal chains. |
| Low quiescent current (350 µA/ch) | Reduces self-heating and extends battery life in portable diagnostic equipment and remote sensors. |
| Industry-standard SOIC-8 footprint | Ensures drop-in compatibility with legacy LM358/LM2904-based PCBs and reflow soldering profiles. |

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 | Wider temp range (0°C to 70°C), higher VOS (7 mV max), same SOIC-8 package and pinout. | Not qualified for extended industrial environments; unsuitable for –25°C cold-start scenarios. | Select LM358DR only for commercial-grade cost-sensitive designs where ambient stays >0°C. |
| LM2904DR | Extended temp range (–40°C to 125°C), same VOS (7 mV max), identical SOIC-8 mechanical form factor. | Higher thermal robustness enables use in automotive engine compartments and outdoor inverters. | Choose LM2904DR when operating below –25°C or above 85°C is required; no PCB change needed. |
Compared with LM258DRG4, LM358DR trades temperature range for lower cost in benign environments, while LM2904DR extends thermal capability without altering layout-making LM258DRG4 the optimal balance for fixed industrial deployments between –25°C and +85°C.

FAQ
What is the maximum supply voltage rating for LM258DRG4?
The LM258DRG4 has an absolute maximum supply voltage of ±16 V or 32 V total (V+ to V−), as specified in the Absolute Maximum Ratings table. Operation beyond this risks permanent damage. For reliable long-term use, TI recommends staying within the Recommended Operating Conditions range of 3 V to 32 V, with derating advised above 85°C ambient.
Does LM258DRG4 support rail-to-rail input and output?
The LM258DRG4 supports rail-to-rail input - its common-mode range includes the negative supply rail (V−) - but does not provide rail-to-rail output swing on the positive side. Output typically swings to within 1.5 V of V+ and within 5–20 mV of V− under 5 V supply, as confirmed in the Electrical Characteristics tables for LM258/LM258A.
What is the input offset voltage specification for LM258DRG4?
The LM258DRG4 has a maximum input offset voltage of 5 mV at 25°C, with typical value of 3 mV. Over the full operating temperature range of –25°C to +85°C, the offset remains within 9 mV maximum, as documented in the LM258/LM258A Electrical Characteristics section (SLOS068W, Table 7.9).
Is LM258DRG4 pin-compatible with LM358DR or LM2904DR?
Yes - LM258DRG4, LM358DR, and LM2904DR all use the standard 8-pin SOIC package with identical pinout (OUT1, IN1−, IN1+, V−, IN2+, IN2−, OUT2, V+). Mechanical and electrical pin compatibility is confirmed in TI's Device Information table and Pin Configuration diagrams (SLOS068W, pages 5–6).
What thermal metrics apply to LM258DRG4 in SOIC-8 package?
For the LM258DRG4 in SOIC-8 (D package), junction-to-ambient thermal resistance (RθJA) is 124.7°C/W, junction-to-board (RθJB) is 67.9°C/W, and junction-to-case (top) is 66.9°C/W - values confirmed in Section 7.4 Thermal Information of the SLOS068W datasheet.
