Product details
Overview
LM1458M/NOPB from Texas Instruments is a dual general-purpose operational amplifier in an 8-pin SOIC package, featuring ±18V supply voltage rating, 5.6 mA max supply current per amplifier pair, 160 V/mV large-signal voltage gain, ±14 V output swing (RL ≥10 kΩ), 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 LM1458M/NOPB datasheet, LM1458M/NOPB pinout, LM1458M/NOPB application, or LM1458M/NOPB equivalent, this page delivers verified electrical specs, SOIC-8 terminal mapping, real-world use cases, and two validated alternative op-amps with documented parameter trade-offs.
Technical Context
The LM1458M/NOPB integrates two independent high-gain DC-coupled amplifiers sharing only bias circuitry and power rails. It requires no external frequency compensation and avoids latch-up even when input common-mode voltage exceeds supply rails.
Its internal architecture supports rail-to-rail input voltage range up to ±12 V (at ±15 V supply), 90 dB supply rejection ratio, and 70 dB common-mode rejection ratio - enabling stable operation in noisy industrial environments without additional filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±18 V - sets maximum analog signal headroom and defines safe operating range for single-supply derived rails. |
| Operating Temperature | 0°C to +70°C - qualified for commercial-grade applications; not rated for extended industrial or automotive ranges. |
| Large-Signal Voltage Gain | 20–160 V/mV - determines closed-loop precision in unity-gain buffers or low-gain instrumentation stages. |
| Input Offset Voltage | 1.0–6.0 mV - directly impacts DC accuracy in summing amplifiers or sensor front-ends without trimming. |
| Output Voltage Swing | ±12 V to ±14 V (RL ≥2 kΩ) - defines usable dynamic range before clipping in line-driver or active filter designs. |
| Supply Current (both amps) | 3.0–5.6 mA at ±15 V - enables low-power analog subsystems where quiescent current affects thermal budget. |
| Input Bias Current | 200–500 nA - limits leakage-induced error in high-impedance transducer interfaces (e.g., piezoelectric sensors). |
Pinout & Package
LM1458M/NOPB uses an 8-pin SOIC (Small Outline Integrated Circuit) package per JEDEC MS-012 variation AA, 1.75 mm max height, with gull-wing leads and pin 1 marked by a beveled corner or notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier A) | Accepts negative feedback or signal inversion node for first op-amp channel. |
| 2 | Non-Inverting Input (Amplifier A) | Reference point for positive signal injection or reference biasing in A-channel. |
| 3 | Output (Amplifier A) | Delivers amplified, buffered, or filtered analog output from first amplifier stage. |
| 4 | V− (Negative Supply) | Common ground or negative rail connection shared by both amplifiers. |
| 5 | Output (Amplifier B) | Delivers amplified, buffered, or filtered analog output from second amplifier stage. |
| 6 | Non-Inverting Input (Amplifier B) | Reference point for positive signal injection or reference biasing in B-channel. |
| 7 | Inverting Input (Amplifier B) | Accepts negative feedback or signal inversion node for second op-amp channel. |
| 8 | V+ (Positive Supply) | Common positive rail connection shared by both amplifiers. |
Key Features
| Feature | Design Value |
|---|---|
| No external frequency compensation required | Enables stable unity-gain operation without added capacitors - reduces BOM count and layout area. |
| Short-circuit protection | Prevents device destruction during output overload or accidental grounding - improves field reliability. |
| Wide common-mode input range | Accepts inputs up to ±12 V at ±15 V supply - supports direct interfacing with unbuffered sensors or DAC outputs. |
| No latch-up on overvoltage | Continues functional operation even if input common-mode exceeds supply rails - eliminates system resets in transient conditions. |
| Low-power consumption | 5.6 mA max total supply current allows battery-powered or thermally constrained analog modules. |
Applications
| Industrial Sensor Signal Conditioning | Audio Pre-Amplification Stage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2904DR | Wider temperature range (−40°C to +125°C); lower input offset (3 mV typ); higher PSRR (100 dB); SOIC-8 compatible. | Preferred for automotive or extended-temperature industrial use; better DC accuracy in precision sensing. | Select LM2904DR when ambient temperature exceeds +70°C or when <3 mV offset is required. |
| TL072CDR | FET-input architecture; lower input bias current (65 pA); higher slew rate (13 V/µs); higher GBP (3 MHz); same SOIC-8 footprint. | Better suited for high-frequency AC-coupled audio or wideband signal paths; unsuitable for high-impedance DC sensors due to gate leakage sensitivity. | Choose TL072CDR for audio, RF coupling, or fast transient response - avoid for DC-coupled microvolt-level sensor amps. |
Compared with LM1458M/NOPB, LM2904DR offers extended temperature capability and tighter DC specs but lacks short-circuit protection; TL072CDR delivers superior AC performance and ultra-low bias current but requires careful guarding and cannot tolerate input overvoltage beyond rails.

FAQ
What is the maximum supply voltage for LM1458M/NOPB?
The LM1458M/NOPB has an absolute maximum supply voltage of ±18 V. Operation beyond this limit risks permanent damage. At ±15 V supply, it delivers ±14 V output swing into 10 kΩ loads - making it suitable for standard dual-rail analog systems. Always observe derating curves above +70°C ambient.
Does LM1458M/NOPB require external compensation capacitors?
No, the LM1458M/NOPB is internally compensated for unity-gain stability. Unlike some decompensated op-amps, it operates reliably in voltage-follower or gain-of-1 configurations without added capacitors - simplifying layout and reducing component count in basic amplification stages.
What is the input offset voltage specification for LM1458M/NOPB?
The LM1458M/NOPB specifies input offset voltage from 1.0 mV (min) to 6.0 mV (max) at 25°C. This parameter directly affects DC accuracy in precision summing, differential amplification, or sensor bridge interfaces - users should plan for trimming or calibration if sub-millivolt error is required.
Is LM1458M/NOPB pin-compatible with LM2904 or TL072?
LM1458M/NOPB shares the same SOIC-8 pinout as LM2904DR and TL072CDR - all follow standard dual-op-amp pin assignment (pins 1–3/A, 4/V−, 5–7/B, 8/V+). However, functional differences in input stage, protection, and rail tolerance mean direct substitution requires validation of bias current, offset, and overvoltage behavior in the target circuit.
What packaging and RoHS status does LM1458M/NOPB have?
LM1458M/NOPB is supplied in an 8-pin SOIC (D) package with matte tin (SN) lead finish, RoHS-compliant, and MSL Level-1 (unlimited floor life at ≤30°C/60% RH). Each tube contains 95 units; tape-and-reel version LM1458MX/NOPB ships in 2500-unit reels - both meet IPC/JEDEC J-STD-020 reflow standards.
