Product details
Overview
LM1458MX/NOPB from Texas Instruments is a dual general-purpose operational amplifier in an 8-pin SOIC package, featuring ±18V maximum supply voltage, 5.6 mA typical supply current per amplifier, 160 V/mV large-signal voltage gain, and guaranteed operation from 0°C to +70°C - used in analog signal conditioning, sensor interface, and industrial control feedback loops.
For engineers reviewing the LM1458MX/NOPB datasheet, LM1458MX/NOPB pinout, LM1458MX/NOPB application, or LM1458MX/NOPB equivalent, this page delivers verified electrical specs, SOIC-8 terminal mapping, real-world use cases, and two validated alternative op-amps for design continuity and sourcing flexibility.
Technical Context
The LM1458MX/NOPB integrates two independent high-gain DC-coupled amplifiers sharing only bias circuitry and power rails. Its internal architecture requires no external frequency compensation, enabling stable unity-gain operation without added components.
It delivers ±14 V output swing into 10 kΩ at ±15 V supplies, supports ±12 V common-mode input range, and provides 90 dB supply voltage rejection - making it suitable for single-supply-derived split-rail systems with moderate precision requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±18 V max - sets absolute rail limits for safe operation with standard ±15 V lab supplies and margin for transient spikes. |
| Large-Signal Voltage Gain | 20–160 V/mV - enables ≥40 dB open-loop gain at 10 V output swing, sufficient for basic closed-loop configurations like inverting/non-inverting amplifiers. |
| Input Offset Voltage | 1.0–6.0 mV - defines worst-case DC error at input; impacts accuracy in low-level signal amplification (e.g., thermocouple interfaces). |
| Supply Current (both amps) | 3.0–5.6 mA - determines total quiescent power draw (~85 mW at ±15 V), suitable for non-battery-critical industrial modules. |
| Output Voltage Swing | ±12 V min into 2 kΩ - ensures usable dynamic range near supply rails for driving analog inputs of ADCs or comparators. |
| Common-Mode Rejection | 70–90 dB - suppresses noise coupled equally to both inputs, critical in noisy industrial environments with long sensor leads. |
| Operating Temperature | 0°C to +70°C - qualifies for commercial-grade equipment (e.g., test instruments, HVAC controllers), not extended or automotive grades. |
Pinout & Package
LM1458MX/NOPB uses an 8-pin SOIC (Package D, JEDEC MS-012AA) with 1.27 mm pitch, 3.9 mm body width, and 1.75 mm max height - compatible with standard surface-mount reflow profiles (Level-1, 260°C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Amplifier A Output | Drives external load or feedback network; limited to ±14 V swing into 10 kΩ. |
| 2 | Amplifier A Inverting Input | Accepts feedback signal; high-impedance node requiring guarded layout to minimize leakage-induced offset. |
| 3 | Amplifier A Non-Inverting Input | Reference or sensor input node; common-mode range extends to ±12 V with ±15 V supplies. |
| 4 | V− Supply | Negative rail connection shared by both amplifiers; must be decoupled locally with 0.1 µF ceramic capacitor. |
| 5 | Amplifier B Non-Inverting Input | Independent input for second channel; electrically isolated from Amp A except via shared supply and bias. |
| 6 | Amplifier B Inverting Input | Feedback node for second amplifier; same impedance and noise sensitivity as Pin 2. |
| 7 | Amplifier B Output | Second independent output; identical AC/DC performance to Pin 1 under matched loading. |
| 8 | V+ Supply | Positive rail for both amplifiers; ties directly to internal bias generator and output stage drivers. |
Key Features
| Feature | Design Value |
|---|---|
| No external frequency compensation required | Enables stable unity-gain operation without added capacitors - reduces BOM count and PCB area in basic gain stages. |
| Short-circuit protection on outputs | Allows indefinite output shorting to either rail without damage - improves robustness in field-deployed sensor front-ends. |
| Wide common-mode input range | ±12 V at ±15 V supplies - supports direct interfacing to transducers operating near supply rails without level-shifting. |
| Independent amplifier operation | Two fully isolated gain blocks share only bias and supply pins - permits mixed-function use (e.g., one as comparator, one as integrator). |
| Low input bias current (200–500 nA) | Minimizes voltage error across high-impedance sources (e.g., pH electrodes, photodiode TIA feedback networks). |
Applications
| Industrial Sensor Signal Conditioning | Audio Pre-Amplification Stage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM258DR | Wider temperature range (−25°C to +85°C); lower input offset (3 mV max); higher CMRR (100 dB). | Better suited for outdoor or uncontrolled ambient deployments where thermal drift matters more than cost. | Select LM258DR when improved DC precision and extended temp range justify minor cost increase over LM1458MX/NOPB. |
| TL072CDR | JFET-input architecture; lower input bias current (65 pA); higher slew rate (13 V/µs); no short-circuit protection. | Preferred for high-impedance, wideband signal paths (e.g., guitar preamps), but unsuitable for fault-prone industrial loads. | Choose TL072CDR only if low input current and bandwidth outweigh need for output short-circuit resilience in LM1458MX/NOPB's target use cases. |
Compared with LM258DR and TL072CDR, the LM1458MX/NOPB offers proven ruggedness and cost-effective dual-amplifier integration for commercial-grade analog signal chains where moderate precision and built-in fault tolerance are prioritized over ultra-low drift or high speed.

The LM1458MX/NOPB has an absolute maximum supply voltage of ±18 V. Operation beyond this limit risks permanent damage. For reliable long-term use, TI recommends staying within ±15 V, which aligns with its specified electrical characteristics and ensures full compliance with the 0°C to +70°C operating temperature range.
Does LM1458MX/NOPB require external compensation capacitors?
No, the LM1458MX/NOPB is internally compensated for unity-gain stability. Unlike some older op-amps, it does not require external capacitors to prevent oscillation - simplifying circuit design and reducing component count in basic amplifier configurations such as buffers or gain-of-ten stages.
Is LM1458MX/NOPB pin-compatible with LM1458N/NOPB?
Yes, LM1458MX/NOPB (SOIC-8) and LM1458N/NOPB (PDIP-8) share identical pinouts and electrical specifications. However, their packages differ mechanically - SOIC requires reflow soldering and smaller board area, while PDIP supports through-hole prototyping and socket-based testing.
What is the input offset voltage specification for LM1458MX/NOPB?
The LM1458MX/NOPB has an input offset voltage ranging from 1.0 mV (minimum) to 6.0 mV (maximum) at 25°C. This parameter directly affects DC accuracy in precision amplification tasks; users should include trimming provisions or select higher-precision alternatives like LM258DR if sub-millivolt error is required.
Can LM1458MX/NOPB drive a 2 kΩ load effectively?
Yes, the LM1458MX/NOPB delivers ±10 V minimum output swing into a 2 kΩ load at ±15 V supplies - meeting typical requirements for driving ADC reference inputs or analog multiplexer channels.
