Product details
Overview
LM258H/NOPB from Texas Instruments is a dual, low-power, internally frequency-compensated operational amplifier optimized for single-supply operation from 3 V to 32 V (or ±1.5 V to ±16 V), featuring 1 MHz unity-gain bandwidth, 100 dB DC open-loop gain, 2 mV input offset voltage, and rail-to-rail output swing capability down to ground-enabling direct sensing of signals referenced to GND in battery-powered sensor interfaces and industrial signal conditioning circuits.
For engineers reviewing the LM258H/NOPB datasheet, LM258H/NOPB pinout, LM258H/NOPB application, or LM258H/NOPB equivalent, this page delivers verified electrical parameters, package-specific terminal mapping, real-world use cases in 4–20 mA transmitters and active filters, and two validated alternative op-amps with documented functional and thermal differences.
Technical Context
The LM258H/NOPB implements a PNP-input stage architecture enabling input common-mode voltage range extending to ground and differential input voltage tolerance up to the full supply rail. Its class-A/class-B hybrid output stage supports both sourcing and sinking of ≥20 mA while maintaining low quiescent current (500 μA typical) across 3 V–32 V supply range.
Internally compensated for unity-gain stability, the device exhibits temperature-compensated unity-gain crossover frequency and input bias current-critical for consistent performance in ambient-varying environments like industrial control panels and automotive body electronics. It operates over −25°C to +85°C, distinguishing it from the wider-temperature LM158 and narrower LM358 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 32 V single supply (±1.5 V to ±16 V dual); enables direct interface with 3.3-V/5-V digital systems without level-shifting. |
| Unity-Gain Bandwidth | 1 MHz (temperature compensated); ensures stable closed-loop gain up to ~10 kHz at gain = 100 without external compensation. |
| DC Open-Loop Gain | 100 dB (10⁵ V/V); provides ≤0.1% gain error in precision DC amplification stages with feedback resistors ≤1 MΩ. |
| Input Offset Voltage | 2 mV (max at 25°C); limits initial error to <10 mV in 5-V full-scale instrumentation amplifier front-ends. |
| Quiescent Supply Current | 500 μA per amplifier (typical, independent of supply voltage); supports multi-channel battery-operated designs with >1-year shelf life. |
| Output Voltage Swing | VOL = 20 mV (at 5 V, RL = 10 kΩ); allows true 0-V output in single-supply configurations-critical for driving ADC reference inputs or logic thresholds. |
| Input Common-Mode Range | Includes ground (0 V) to V+ − 1.5 V; eliminates need for input biasing networks in ground-referenced transducer amplifiers. |
Pinout & Package
LM258H/NOPB is packaged in an 8-pin SOIC (D) package with 4.90 mm × 3.91 mm body size and standard 1.27 mm pitch. Pin functions are electrically identical across LMx58-N family members in SOIC format.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA (Pin 1) | Output, Channel A | Capable of sourcing/sinking ≥20 mA; swings within 20 mV of ground and within 2 V of V+ at 5 V supply. |
| –INA (Pin 2) | Inverting Input, Channel A | PNP-based input; draws ~45 nA bias current (typ), direction outward from IC-no loading variation with output state. |
| +INA (Pin 3) | Non-inverting Input, Channel A | Accepts common-mode voltages from 0 V to V+ − 1.5 V; enables direct connection of grounded sensors. |
| GND / V– (Pin 4) | Ground / Negative Supply | Serves as return path in single-supply mode; doubles as negative rail in dual-supply configuration. |
| +INB (Pin 5) | Non-inverting Input, Channel B | Electrically identical to +INA; supports independent dual-channel signal processing without cross-talk. |
| –INB (Pin 6) | Inverting Input, Channel B | Matches –INA characteristics; allows matched feedback networks for dual-opamp circuits like instrumentation amps. |
| OUTB (Pin 7) | Output, Channel B | Functionally identical to OUTA; permits simultaneous dual-stage gain/level-shifting with shared supply. |
| V+ (Pin 8) | Positive Supply | Accepts 3–32 V; internal bias network draws constant 500 μA regardless of voltage-ideal for unregulated battery rails. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation with ground-sensing inputs | Enables direct interfacing of thermocouples, strain gauges, and current-sense shunts without external level-shifting circuitry. |
| Temperature-compensated unity-gain crossover | Maintains stable 1 MHz bandwidth across −25°C to +85°C-critical for consistent filter cutoffs in environmental monitoring. |
| Low input bias current with PNP input stage | 45 nA typical (25°C); minimizes voltage drop across high-impedance sources (e.g., pH electrodes, photodiode transimpedance amps). |
| Rail-to-ground output swing | VOL ≤ 20 mV at 5 V/10 kΩ load; allows full utilization of 0–5 V ADC input ranges and direct drive of CMOS logic inputs. |
| Internal frequency compensation | Eliminates need for external compensation capacitors in unity-gain buffers and non-inverting amplifiers-reducing BOM count and layout area. |

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 | Same SOIC-8 package and pinout; wider operating temperature range (0°C to 70°C vs. −25°C to 85°C for LM258H/NOPB); higher input offset voltage (7 mV max vs. 5 mV max). | Preferred for commercial-grade consumer electronics where extended temperature is unnecessary and cost is critical. | Select LM358DR only when ambient operating temperature remains within 0–70°C and 2 mV offset tolerance is acceptable. |
| LM2904DR | Identical SOIC-8 footprint; rated for −40°C to 85°C; higher input bias current (250 nA typ vs. 45 nA typ); lower CMRR (50 dB min vs. 70 dB min). | Suitable for automotive under-hood applications requiring extended cold-start capability but less demanding on precision. | Choose LM2904DR when operating below −25°C is required and reduced DC accuracy can be tolerated in signal chain calibration. |
Compared with LM358DR and LM2904DR, LM258H/NOPB offers superior DC precision (2 mV offset, 70 dB CMRR) and optimal thermal range (−25°C to 85°C) for industrial control modules-making it the preferred choice where accuracy and moderate environmental robustness intersect.

FAQ
What is the maximum operating temperature for LM258H/NOPB?
The LM258H/NOPB is rated for operation from −25°C to +85°C. This temperature range is confirmed in Section 6.3 "Recommended Operating Conditions" of the official TI datasheet SNOSBT3J. Exceeding +85°C may cause parametric shift beyond specifications, particularly in input offset voltage and supply current. For applications requiring wider thermal margins, consider LM158-N (−55°C to +125°C) or LM2904-N (−40°C to +85°C). The LM258H/NOPB's thermal specification directly supports industrial control cabinet deployments.
Does LM258H/NOPB support true rail-to-rail output?
The LM258H/NOPB does not provide rail-to-rail output swing on the positive side-it typically swings within 2 V of V+ at 5 V supply-but it does deliver rail-to-ground output (VOL ≤ 20 mV at 5 V/10 kΩ), as specified in Section 6.5 Electrical Characteristics. This asymmetric swing is intentional for its PNP-input architecture and enables reliable 0-V output in single-supply systems. Full rail-to-rail output requires newer-generation op-amps such as TLV2462 or OPA2333. The LM258H/NOPB's ground-swing capability remains a key differentiator versus older LM358 variants in sensor front-ends.
Can LM258H/NOPB be used with a 3.3-V supply?
Yes, LM258H/NOPB is fully specified for operation down to 3 V single supply (Section 6.3), making it compatible with standard 3.3-V digital systems. At 3.3 V, it maintains 1 MHz unity-gain bandwidth, 500 μA supply current, and ground-swing output (VOL ≤ 30 mV typical). Its input common-mode range extends to 0 V, allowing direct connection of 3.3-V-compatible sensors without level-shifting. This capability is explicitly validated in TI's application note SLOA074A for low-voltage signal conditioning. LM258H/NOPB thus bridges legacy analog needs with modern low-voltage platforms.
What is the input bias current polarity and magnitude for LM258H/NOPB?
The LM258H/NOPB features a PNP-input stage, resulting in input bias current that flows *out* of the input terminals-not into them-with a typical value of 45 nA at 25°C (Section 6.5). This outward current direction is constant and independent of output state, eliminating dynamic loading effects on high-impedance sources. It differs fundamentally from NMOS-input op-amps (e.g., TLC27L2), which draw current *into* inputs. This characteristic makes LM258H/NOPB especially suitable for photodiode transimpedance amplifiers and high-Z sensor buffering where leakage-induced offset must be minimized.
Is LM258H/NOPB pin-compatible with LM358 or LM2904 in SOIC-8 packages?
Yes, LM258H/NOPB is pin-compatible with LM358DR and LM2904DR in the SOIC-8 (D) package-same pinout, same footprint, same solder profile. However, electrical behavior differs: LM258H/NOPB offers tighter input offset (2 mV max vs. 7 mV for LM358), better CMRR (70 dB vs. 65 dB), and −25°C to +85°C rating (vs. 0°C–70°C for LM358, −40°C–85°C for LM2904). While PCB layout is interchangeable, system-level validation is required due to these parametric variances-especially in precision or wide-temperature applications. LM258H/NOPB is not a drop-in replacement without functional review.
