Overview
LM158AH/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-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 LM158AH/NOPB datasheet, LM158AH/NOPB pinout, LM158AH/NOPB application, or LM158AH/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 LM158AH/NOPB implements a PNP-input stage enabling input common-mode voltage range that includes ground-even under single-supply operation-and supports true-differential inputs with differential input voltage tolerance up to the full supply rail. Its class-A/class-B hybrid output stage delivers both sourcing and sinking capability while maintaining low quiescent current (500 μA typical).
Internally compensated for unity-gain stability, the device exhibits temperature-compensated unity-gain crossover frequency and input bias current, ensuring consistent small-signal performance across −55°C to +125°C operating range. Input offset voltage drift is specified at 7 μV/°C, supporting precision DC-coupled amplification in harsh environments.

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 | Lower temperature grade (0°C to 70°C); higher input offset voltage (7 mV max); same pinout and SOIC-8 package. | Suitable for commercial-grade consumer electronics but not qualified for extended industrial or military temperature ranges. | Select LM358DR only if ambient operating temperature remains within 0–70°C and offset drift is acceptable. |
| LM2904VQDR | Automotive AEC-Q100 Grade 1 (−40°C to +125°C); tighter input offset voltage (2 mV max); same electrical specs except PSRR reduced to 50 dB. | Validated for automotive body control modules and ADAS sensor interfaces requiring automotive qualification. | Choose LM2904VQDR when AEC-Q100 compliance and extended high-temp stability are mandatory. |
Compared with LM158AH/NOPB, LM358DR trades military-grade temperature range and lower offset for cost and commercial availability, while LM2904VQDR adds automotive qualification and matching offset performance but reduces power supply rejection-making LM158AH/NOPB optimal for high-reliability industrial systems needing guaranteed −55°C to +125°C operation and 85 dB CMRR.

FAQ
What is the maximum operating temperature range for LM158AH/NOPB?
The LM158AH/NOPB is rated for operation from −55°C to +125°C, as confirmed in Section 6.3 of the official TI datasheet SNOSBT3J. This extended temperature range is enabled by its TO-CAN (8) metal-can package and internal design optimizations, distinguishing it from commercial variants like LM358 (0°C to 70°C) and making it suitable for aerospace and military applications where thermal extremes are expected. The LM158AH/NOPB maintains full electrical specifications across this entire range.
Does LM158AH/NOPB support true rail-to-rail output swing?
The LM158AH/NOPB does not provide full rail-to-rail output swing. Its output can swing to within approximately 20 mV of ground (V–) and within about 2 V of the positive supply (V+) under RL = 10 kΩ load conditions, as specified in Section 6.5 of the datasheet. While this "output-to-ground" capability enables single-supply operation with grounded sensors, it lacks the high-side rail reach of modern RRO op-amps. The LM158AH/NOPB achieves usable dynamic range in most industrial signal chains but requires headroom above V+ for saturated output states.
Can LM158AH/NOPB be used with a 3.3 V single supply?
Yes, LM158AH/NOPB is fully functional with a 3.3 V single supply, as its minimum recommended supply voltage is 3 V per Section 6.3 of the datasheet. At 3.3 V, it maintains 100 dB open-loop gain, 1 MHz unity-gain bandwidth, and input common-mode range extending to ground-making it ideal for interfacing with 3.3 V microcontrollers and low-voltage sensors. However, output swing is reduced: VOL ≈ 20 mV (to ground) and VOH ≈ 1.3 V (from V+), so design margins must account for this compressed headroom.
What is the input bias current specification for LM158AH/NOPB?
The LM158AH/NOPB features a PNP input stage with input bias current of 45 nA typical and 150 nA maximum at TA = 25°C, as stated in Section 6.5 of the datasheet. Critically, this bias current is temperature-compensated, minimizing drift over the full −55°C to +125°C range. Unlike CMOS op-amps, the current flows *out* of the input terminals, which affects high-impedance source designs-e.g., requiring guard traces or bias current cancellation resistors in precision integrators or photodiode transimpedance amplifiers using LM158AH/NOPB.
Is LM158AH/NOPB pin-compatible with LM358N?
No, LM158AH/NOPB is not pin-compatible with LM358N. LM158AH/NOPB uses an 8-pin TO-CAN (metal can) package with leads arranged in a circular configuration, while LM358N is typically supplied in PDIP-8 or SOIC-8 packages with standard dual-in-line or surface-mount lead spacing. Although both share identical pin functions (e.g., Pin 1 = OUTA, Pin 2 = –INA), their physical footprints, thermal characteristics, and mounting methods differ fundamentally. PCB layout must be redesigned to accommodate the TO-CAN can body and radial lead form of LM158AH/NOPB.
