Product details
Overview
MC1458PG4 from Texas Instruments is a dual general-purpose operational amplifier with each amplifier electrically similar to the μA741 (excluding offset null), featuring ±15 V supply capability, 6 mV max input offset voltage at 25°C, and short-circuit protection - widely used in industrial signal conditioning and analog sensor interface circuits.
For engineers reviewing the MC1458PG4 datasheet, MC1458PG4 pinout, MC1458PG4 application, or MC1458PG4 equivalent, this page delivers verified electrical specs, PDIP-8 package details, thermal performance data, and real-world design context for legacy analog system maintenance and drop-in replacement evaluation.
Technical Context
The MC1458PG4 implements internally compensated DC-coupled op-amp stages with no external frequency compensation required, enabling stable unity-gain operation. Its high common-mode input voltage range (±12 V) and absence of latch-up support robust voltage-follower and transducer interface configurations.
Designed as a direct functional replacement for Motorola MC1458/MC1558 and Signetics S5558/N5558, it maintains compatibility with legacy μA741-based designs while delivering 1 MHz unity-gain bandwidth, 0.5 V/μs slew rate, and 70 dB minimum CMRR across its 0°C to 70°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±15 V - supports standard dual-rail analog systems without level-shifting. |
| Input Offset Voltage | 6 mV max at 25°C - defines worst-case DC error in precision gain stages and active filters. |
| Unity-Gain Bandwidth | 1 MHz - sets upper limit for stable closed-loop operation at AV = 1. |
| Slew Rate | 0.5 V/μs - constrains large-signal response time in pulse amplification and waveform generation. |
| Common-Mode Input Range | ±12 V - enables rail-to-rail input operation within ±15 V supplies for sensor front-ends. |
| Short-Circuit Protection | Unlimited duration - allows safe operation during output faults without device damage. |
| Operating Temperature | 0°C to 70°C - qualified for commercial-grade industrial control and test equipment. |
Pinout & Package
MC1458PG4 is housed in an 8-pin plastic dual in-line package (PDIP) with 0.3-inch body width and through-hole mounting. Thermal resistance θJA is 85°C/W, supporting up to 170 mW total power dissipation at 25°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output of Amplifier 1 | Provides buffered, inverted or non-inverted signal depending on configuration. |
| 2 | Inverting Input of Amplifier 1 | Accepts feedback network connection for closed-loop gain control. |
| 3 | Non-Inverting Input of Amplifier 1 | Connects to reference or sensor signal in follower or summing applications. |
| 4 | Negative Supply (VCC−) | Ground reference for dual-supply operation; must be connected to −VCC. |
| 5 | Positive Supply (VCC+) | Power rail connection; requires decoupling capacitor near pin for stability. |
| 6 | Output of Amplifier 2 | Independent output stage for second channel; shares same supply pins. |
| 7 | Inverting Input of Amplifier 2 | Enables dual-channel signal processing without cross-talk above 120 dB. |
| 8 | Non-Inverting Input of Amplifier 2 | Supports independent biasing or differential input pairing with Amp 1. |
Key Features
| Feature | Design Value |
|---|---|
| No external frequency compensation required | Reduces BOM count and PCB area by eliminating external compensation capacitors. |
| Wide common-mode input voltage range | ±12 V enables direct interfacing with ±10 V industrial sensors and DAC outputs. |
| Short-circuit protected outputs | Eliminates need for external current-limiting resistors in drive-stage designs. |
| No latch-up behavior | Ensures reliable operation during overvoltage transients or power sequencing mismatches. |
| Low power consumption | 3.4–5.6 mA per amplifier supports thermally constrained legacy instrumentation. |
Applications
| Industrial Sensor Signal Conditioning | Legacy Test Equipment Amplification |
|---|---|
|
Use Scenario: Amplifying low-level outputs from strain gauges, RTDs, and thermocouples in PLC analog input modules. IC Role / Device Role / Timing Role: Dual-channel DC-coupled amplifier providing gain, filtering, and level-shifting before ADC sampling. Use Value: ±12 V common-mode range accepts sensor bridge excitation directly; 6 mV offset ensures <0.1% full-scale error in 10-bit systems. |
Use Scenario: Replacing obsolete μA741 or MC1458 variants in aging oscilloscope vertical deflection amplifiers and function generator output stages. IC Role / Device Role / Timing Role: Stable unity-gain buffer and active filter component maintaining original timing and amplitude fidelity. Use Value: Internally compensated 1 MHz bandwidth preserves rise time integrity; short-circuit protection prevents field failure during probe shorts. |
| Analog Audio Pre-Amplification | DC Motor Speed Reference Circuitry |
|
Use Scenario: Low-noise pre-amplification of line-level audio signals in vintage audio test gear and calibration sources. IC Role / Device Role / Timing Role: Dual op-amp configured as non-inverting gain stage and active low-pass filter. Use Value: 45 nV/√Hz input noise meets SNR requirements for 16-bit audio paths; dual layout minimizes inter-channel crosstalk (120 dB). |
Use Scenario: Generating stable, adjustable speed reference voltages for analog-controlled DC motor drives in factory automation systems. IC Role / Device Role / Timing Role: Precision voltage follower and summing amplifier combining setpoint, feedback, and trim signals. Use Value: No latch-up and wide input range tolerate back-EMF coupling; 0.5 V/μs slew rate avoids distortion in ramped speed commands. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual general-purpose op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DR | Single-supply rated (3–32 V), lower input offset (7 mV typ), no negative rail requirement. | Better suited for battery-powered or microcontroller-based systems with 0–5 V rails. | Select LM358DR only when redesigning for single-supply operation; not pin-compatible with MC1458PG4. |
| TL082CP | JFET-input architecture, higher slew rate (13 V/μs), wider bandwidth (3 MHz), but higher input bias current (30 pA). | Preferred for high-frequency AC-coupled signal chains where speed outweighs DC precision. | Choose TL082CP for new designs needing faster settling; requires layout review due to different noise and stability behavior. |
Compared with LM358DR and TL082CP, MC1458PG4 provides proven dual-rail stability and legacy footprint compatibility - critical for repair, calibration, and long-lifecycle industrial hardware where supply topology and pinout must remain unchanged.

FAQ
What is the maximum supply voltage rating for MC1458PG4?
The MC1458PG4 supports a maximum supply voltage of ±18 V across VCC+ and VCC−. Exceeding this absolute maximum rating may cause permanent damage. For reliable operation, TI specifies ±5 V to ±15 V under recommended conditions - aligning with standard dual-rail analog systems where MC1458PG4 is commonly deployed.
Does MC1458PG4 include input offset null capability?
No, MC1458PG4 does not provide offset null pins or internal trimming capability. It is electrically similar to the μA741 except for this omission. Designers requiring fine DC offset adjustment must implement external nulling circuitry or select alternatives like the LM741CH, which retains dedicated null pins - a key distinction confirmed in the official SLOS069C datasheet.
Is MC1458PG4 RoHS compliant?
Yes, MC1458PG4 is RoHS compliant, as confirmed by TI's packaging documentation. The "G4" suffix denotes lead-free finish (NiPdAu over Cu), and the part meets JEDEC J-STD-020 moisture sensitivity Level 1 with peak reflow at 260°C - making it suitable for modern automated assembly processes without exemption waivers.
How does MC1458PG4 differ from MC1558 in temperature range and offset voltage?
MC1458PG4 is rated for 0°C to 70°C operation with 6 mV max input offset voltage at 25°C, whereas MC1558 operates from −55°C to 125°C and specifies 5 mV max offset. Both share identical pinout and electrical architecture, but MC1558 targets military/aerospace applications requiring extended thermal resilience - a difference explicitly documented in TI's SLOS069C revision history.
Can MC1458PG4 replace older MC1458P or MC1458PE4 parts?
Yes, MC1458PG4 is a direct form-fit-function replacement for MC1458P and MC1458PE4, sharing the same PDIP-8 package, pinout, and electrical specifications. The "G4" suffix indicates updated lead finish and RoHS compliance, while maintaining full compatibility with legacy sockets and schematics - verified via TI's official packaging addendum and orderable part cross-reference tables.
