Product details
Overview
LM1458M-TI from Texas Instruments is a dual general-purpose operational amplifier with independent amplifier sections sharing bias and supply leads, ±18V max supply voltage, 0°C to +70°C operating temperature range, and 5.6 mA max supply current per package. It serves in analog signal conditioning, sensor interface, and active filter circuits where cost-effective dual op-amp performance is required.
For engineers reviewing the LM1458M-TI datasheet, LM1458M-TI pinout, LM1458M-TI application, or LM1458M-TI equivalent, key selection considerations include its guaranteed commercial-temperature specs, SOIC-8 packaging, input offset voltage up to 7.5 mV, and compatibility with ±15 V rail operation in legacy industrial and test equipment designs.
Technical Context
The LM1458M-TI integrates two internally compensated op-amps on a single silicon die with shared power supply pins (V+ and V−) and common bias network, enabling compact dual-amplifier functionality without external compensation. Its architecture supports rail-to-rail input voltage range up to ±12 V with ±15 V supplies and delivers ±13 V output swing into 2 kΩ loads.
It features built-in short-circuit protection and latch-up immunity when input common-mode voltage exceeds rails, making it robust for non-rail-sensing applications. The device exhibits 70 dB minimum CMRR and 77 dB minimum PSRR at 25°C, confirming stable operation under moderate noise and supply variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±18 V max - sets absolute upper limit for bipolar supply operation without damage |
| Operating Temperature | 0°C to +70°C - defines commercial-grade qualification; not rated for extended or military ranges |
| Input Offset Voltage | Up to 7.5 mV - impacts DC accuracy in precision amplification or summing configurations |
| Large-Signal Voltage Gain | 15 V/mV min - ensures ≥15,000 open-loop gain for stable closed-loop behavior at ±10 V output |
| Output Swing (RL = 2 kΩ) | ±10 V min - determines usable dynamic range before clipping in mid-supply applications |
| Supply Current (both amps) | 5.6 mA max - enables low-power dual-op-amp implementation in battery-adjacent or thermally constrained boards |
| Common-Mode Rejection | 70 dB min - suppresses interference from shared ground noise in differential sensing setups |
Pinout & Package
LM1458M-TI is supplied in an 8-pin SOIC package (Package Drawing D, JEDEC MS-012 AA), 3.9 mm width, 1.75 mm max height, RoHS-compliant, tape-and-reel compatible (2500 pcs/reel). Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Amplifier A Output | Drives external load or feedback network for first op-amp stage |
| 2 | Amplifier A Inverting Input | Accepts signal to be inverted or attenuated via resistor network |
| 3 | Amplifier A Non-Inverting Input | Accepts reference or sensor signal for unity-gain buffer or comparator input |
| 4 | V− (Negative Supply) | Common negative rail connection for both amplifiers; must be decoupled locally |
| 5 | Amplifier B Non-Inverting Input | Independent positive-input node for second amplifier section |
| 6 | Amplifier B Inverting Input | Independent negative-input node supporting separate gain-setting resistors |
| 7 | Amplifier B Output | Second independent output channel; no internal cross-coupling with Pin 1 |
| 8 | V+ (Positive Supply) | Common positive rail for both amplifiers; shared bias network originates here |
Key Features
| Feature | Design Value |
|---|---|
| No frequency compensation required | Internal compensation enables stable unity-gain operation without external capacitors |
| Short-circuit protection | Prevents thermal runaway during output overload or accidental grounding |
| Wide common-mode input range | Accepts inputs up to ±12 V with ±15 V supplies-supports high-side sensing without level shifters |
| No latch-up on overvoltage | Continues safe operation even if input exceeds supply rails-critical for transient-prone sensor interfaces |
| Low-power consumption | 5.6 mA total supply current allows dual-channel amplification in space-constrained or thermally sensitive PCB areas |
Applications
| Audio Signal Mixing | Sensor Signal Conditioning |
|---|---|
Use Scenario: Combining multiple line-level audio sources into a single output bus in analog mixing consoles or consumer AV receivers. IC Role / Device Role / Timing Role: Dual op-amp configured as inverting summing amplifier (Channel A) and unity-gain buffer (Channel B) for impedance isolation.

Use Scenario: Replacing obsolete op-amps in calibration modules, oscilloscope vertical amplifiers, and function generator output stages. IC Role / Device Role / Timing Role: Drop-in functional replacement for original LM1458N PDIP units in field-serviceable equipment. Use Value: Identical electrical specs and pinout as legacy through-hole version-enables SOIC retrofit without schematic or layout changes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM1458N/NOPB | Same electrical specs but in 8-pin PDIP package; no moisture sensitivity rating; higher thermal resistance (187°C/W) | Preferred for prototyping, through-hole assembly, or legacy board rework where SOIC footprint is unavailable | Select LM1458N/NOPB when manual soldering, breadboarding, or repairing vintage equipment with DIP sockets is required |
| TL072CDR | Higher slew rate (13 V/µs vs. ~0.5 V/µs), lower input bias current (30 pA vs. 500 nA), JFET input; not pin-compatible | Better suited for high-frequency AC coupling, audio preamps, or low-noise sensor front-ends where LM1458M-TI's BJT input limitations cause drift or distortion | Choose TL072CDR only when upgrading performance-not as drop-in replacement-due to different pin mapping and bias requirements |
Compared with LM1458N/NOPB, LM1458M-TI offers surface-mount compatibility and moisture-safe packaging for automated production; versus TL072CDR, it provides proven reliability in legacy DC-coupled industrial circuits but lacks JFET input advantages for high-Z sources.

FAQ
What is the maximum supply voltage rating for LM1458M-TI?
The LM1458M-TI has an absolute maximum supply voltage of ±18 V. Exceeding this rating risks permanent damage. For reliable operation, TI specifies ±15 V as the recommended maximum supply under normal conditions, aligning with its guaranteed electrical characteristics across the 0°C to +70°C temperature range.
Does LM1458M-TI require external frequency compensation?
No, the LM1458M-TI does not require external frequency compensation. It features internal compensation optimized for stable unity-gain operation, allowing direct use in inverting, non-inverting, and voltage-follower configurations without added capacitors or resistor networks.
Is LM1458M-TI pin-compatible with LM1458N/NOPB?
Yes, LM1458M-TI and LM1458N/NOPB share identical pinouts and electrical specifications. Both use the same 8-pin configuration (V+, B out, B−, B+, A−, A+, V−, A out), enabling direct substitution between SOIC and PDIP packages in existing designs-though thermal and assembly constraints differ.
What is the input offset voltage specification for LM1458M-TI?
The LM1458M-TI has a maximum input offset voltage of 7.5 mV at 25°C, with typical values around 6.0 mV. This parameter directly affects DC accuracy in precision amplification stages and must be considered in summing, integrating, or sensor-offset correction circuits.
Can LM1458M-TI operate with single-supply configurations?
The LM1458M-TI is specified for dual-supply operation (±V), but can be used in single-supply mode with appropriate biasing-e.g., setting V− to ground and V+ to +18 V while referencing inputs to mid-rail. However, input common-mode and output swing limits must be strictly observed to avoid saturation or phase reversal.
