Product details
Overview
LM158H/NOPB from Texas Instruments is a dual, low-power, internally frequency-compensated operational amplifier designed for single-supply operation from 3 V to 32 V (or ±1.5 V to ±16 V), featuring 100 dB DC voltage gain, 1 MHz unity-gain bandwidth, 2 mV input offset voltage, and rail-to-ground output swing - enabling direct sensing of signals referenced to ground in battery-powered industrial sensor interfaces.
For engineers reviewing the LM158H/NOPB datasheet, LM158H/NOPB pinout, LM158H/NOPB application, or LM158H/NOPB equivalent, this page delivers verified electrical parameters, TO-CAN (8) package mapping, functional pin roles, real-world use cases in 4–20 mA transmitters and active filters, and two validated alternative op-amps with documented technical and application-level differences.
Technical Context
The LM158H/NOPB integrates two independent PNP-input op-amps sharing a common bias network that maintains stable 500 μA supply current across 3–32 V supply range. Its input common-mode voltage range includes ground, and output can swing to ground under single-supply conditions - a key enabler for true single-rail signal conditioning.
This device uses internal unity-gain compensation with temperature-stabilized unity-gain crossover frequency and temperature-compensated input bias current. It supports operation down to 2.3 V at 25°C and withstands differential input voltages exceeding V+, with no input protection diodes required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | Single: 3 V to 32 V; dual: ±1.5 V to ±16 V - enables compatibility with legacy 5 V, modern 3.3 V, and high-voltage industrial rails without level-shifting. |
| DC Voltage Gain | 100 dB (100,000×) - ensures high-precision amplification of low-level transducer outputs with minimal error propagation. |
| Unity-Gain Bandwidth | 1 MHz (temperature compensated) - provides stable small-signal response up to audio frequencies in filter and conditioning circuits. |
| Input Offset Voltage | 2 mV (typical, 25°C) - supports accurate DC-coupled amplification in strain gauge and thermocouple front-ends. |
| Supply Current per Amplifier | 500 μA (typical, independent of supply voltage) - enables multi-channel analog signal chains in power-constrained systems like portable instrumentation. |
| Input Common-Mode Range | Includes ground (0 V) to V+ −1.5 V - eliminates need for input biasing resistors when interfacing with ground-referenced sensors. |
| Output Voltage Swing | Swings to ground (rail-to-rail output low) and within 1.5 V of V+ - allows full dynamic range utilization in single-supply 4–20 mA loop drivers. |
Pinout & Package
LM158H/NOPB is housed in an 8-pin TO-CAN (metal can) package measuring 9.08 mm × 9.09 mm, rated for operation from −55°C to +125°C, and intended for high-reliability military/aerospace applications where hermetic sealing and thermal stability are critical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA (Pin 1) | Output, Channel A | Amplified output of first op-amp; capable of sourcing/sinking ≥20 mA and swinging to ground in single-supply mode. |
| –INA (Pin 2) | Inverting Input, Channel A | Differential input node for Channel A; accepts signals from 0 V to V+ −1.5 V without external biasing. |
| +INA (Pin 3) | Non-inverting Input, Channel A | Differential input node for Channel A; supports true ground-referenced input signal acquisition. |
| GND / V– (Pin 4) | Ground / Negative Supply | Reference node for single-supply operation; serves as negative rail in dual-supply configurations. |
| +INB (Pin 5) | Non-inverting Input, Channel B | Second op-amp's non-inverting input; identical functionality and voltage range to Pin 3. |
| –INB (Pin 6) | Inverting Input, Channel B | Second op-amp's inverting input; fully interchangeable with Pin 2 in layout and function. |
| OUTB (Pin 7) | Output, Channel B | Independent output stage mirroring Pin 1; supports concurrent dual-channel signal processing. |
| V+ (Pin 8) | Positive Supply | Main power input; supplies both amplifiers; tolerant of up to 32 V with no derating required below 125°C junction temp. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation with rail-to-ground output | Enables direct interface with 0 V–referenced sensors (e.g., bridge transducers) without level-shifting circuitry or dual supplies. |
| Temperature-compensated unity-gain crossover | Maintains stable 1 MHz bandwidth across −55°C to +125°C, critical for consistent filter cutoff and closed-loop response in harsh environments. |
| Input bias current compensation | Reduces drift-induced errors in high-impedance sensor networks (e.g., pH electrodes), improving long-term DC accuracy. |
| Wide supply range with supply-independent quiescent current | Permits use across multiple voltage domains (3.3 V logic, 12 V industrial, 24 V PLC) while preserving battery life in portable designs. |
| No input protection diodes required | Allows safe handling of differential input voltages exceeding V+ - simplifies front-end design for overvoltage-tolerant measurement systems. |
Applications
| Industrial 4–20 mA Transmitter | Active Low-Pass Filter |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual, low-power, single-supply operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DR | Same pinout and basic specs, but rated only for 0°C to +70°C ambient; higher input offset voltage (7 mV max vs. 5 mV max for LM158H/NOPB). | Not qualified for extended temperature or military-grade systems; suitable for commercial-grade consumer or office equipment. | Select LM358DR only when cost sensitivity outweighs temperature range and DC precision requirements. |
| LM2904VQDR | Automotive-grade (AEC-Q100), wider operating range (−40°C to +125°C), but lower CMRR (50 dB min vs. 70 dB min for LM158H/NOPB) and higher input bias current (250 nA typ). | Validated for automotive body electronics; less suitable for high-precision industrial measurement due to reduced rejection of supply noise. | Choose LM2904VQDR for automotive applications requiring qualification; retain LM158H/NOPB for high-accuracy, wide-temp industrial use. |
Compared with LM358DR and LM2904VQDR, LM158H/NOPB uniquely combines military-grade temperature range (−55°C to +125°C), 2 mV typical offset, and rail-to-ground output - making it the only option among the three qualified for high-reliability analog signal paths in aerospace, defense, and critical infrastructure systems.

FAQ
What is the maximum operating temperature for LM158H/NOPB?
The LM158H/NOPB is specified for operation from −55°C to +125°C ambient temperature, with the "H" suffix denoting the highest-grade military temperature range. This rating is confirmed in Section 6.3 of the official TI datasheet SNOSBT3J, and applies to the TO-CAN (8) package variant. The device maintains full electrical performance across this range, including 100 dB gain and 1 MHz bandwidth.
Does LM158H/NOPB support true single-supply operation with output swing to ground?
Yes, LM158H/NOPB supports true single-supply operation with output swing to ground (rail-to-ground). As stated in the "Description" section and Figure 6-1 of the TI datasheet, its output stage is designed to drive to 0 V when loaded, and its input common-mode range explicitly includes ground - enabling direct connection of ground-referenced sensors without external biasing networks.
What package type is used for LM158H/NOPB?
LM158H/NOPB uses an 8-pin TO-CAN (metal can) package with nominal body size 9.08 mm × 9.09 mm, as documented in the "Device Information" table of the TI datasheet SNOSBT3J. This hermetically sealed package provides superior moisture resistance and thermal stability compared to plastic SOIC or DSBGA variants, supporting its use in high-reliability applications.
How does LM158H/NOPB differ from standard LM358 in terms of specifications?
LM158H/NOPB differs from LM358 in three key ways: (1) extended temperature range (−55°C to +125°C vs. 0°C to +70°C), (2) tighter input offset voltage (2 mV typical vs. 7 mV typical), and (3) guaranteed operation down to 2.3 V supply at 25°C. These differences are explicitly defined in Sections 6.3 and 6.5 of the TI datasheet and reflect its military-grade qualification.
Is LM158H/NOPB pin-compatible with LM358 or LM2904?
LM158H/NOPB shares the same 8-pin DIP/TO-CAN pinout as LM358 and LM2904, and is functionally compatible in standard dual-op-amp circuits. However, it is not a drop-in replacement in all cases: its higher temperature rating, lower offset, and different absolute maximum ratings (e.g., 32 V supply vs. 26 V for LM2904) require validation in safety-critical or high-voltage designs before substitution.
