Product details
Overview
MC1458DRE4 from Texas Instruments is a dual general-purpose operational amplifier in an 8-pin SOIC package, featuring ±15 V supply capability, 6 mV max input offset voltage at 25°C, short-circuit protection, and internal frequency compensation - enabling stable unity-gain follower operation in analog signal conditioning circuits for industrial instrumentation.
For engineers reviewing the MC1458DRE4 datasheet, MC1458DRE4 pinout, MC1458DRE4 application, or MC1458DRE4 equivalent, this page delivers verified electrical parameters, thermal limits, real-world use contexts, and validated alternative options aligned with TI's SLOS069C production data.
Technical Context
The MC1458DRE4 implements two independent high-input-impedance op-amp channels electrically similar to μA741 but without offset null pins. Each channel supports wide common-mode input range (±12 V) and differential input voltage up to ±30 V, with no external compensation required due to built-in dominant-pole architecture.
It operates across 0°C to 70°C ambient temperature, draws 3.4–5.6 mA total supply current, delivers ±12 V peak output swing into 10 kΩ, and provides 1 MHz unity-gain bandwidth with 65° phase margin - ensuring stability in closed-loop configurations without added components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±15 V - supports standard dual-rail analog systems without level-shifting circuitry |
| Input Offset Voltage | Max 6 mV at 25°C - sets DC error floor in precision gain stages and sensor amplifiers |
| Unity-Gain Bandwidth | 1 MHz - enables stable AC-coupled amplification up to audio frequencies |
| Slew Rate | 0.5 V/μs - limits large-signal transient response; suitable for low-frequency signal conditioning |
| Common-Mode Input Range | ±12 V - allows direct interface with sensors operating near rail voltages |
| Short-Circuit Protection | Unlimited duration - permits safe operation during fault conditions without external current limiting |
| Thermal Resistance θJA | 97°C/W (SOIC-D) - defines maximum power dissipation limit under natural convection cooling |
Pinout & Package
MC1458DRE4 uses an 8-pin SOIC (D) package measuring 4.90 mm × 3.91 mm × 1.75 mm, with gull-wing leads and RoHS-compliant NiPdAu plating. Pin 1 is marked by a beveled corner or dot; device orientation follows JEDEC MS-012AA standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output of Amplifier 1 | Provides buffered, inverted or non-inverted signal depending on configuration; drives loads ≥2 kΩ |
| 2 | Inverting Input of Amp 1 | Accepts feedback network connection; sets gain and polarity in closed-loop applications |
| 3 | Non-Inverting Input of Amp 1 | Receives reference or sensor signal; high impedance (>0.3 MΩ) minimizes loading effects |
| 4 | Negative Supply (VCC−) | Reference return for dual-supply operation; must be connected to system ground or negative rail |
| 5 | Positive Supply (VCC+) | Power input for both amplifiers; decoupling capacitor recommended within 1 cm |
| 6 | Output of Amplifier 2 | Independent output stage; crosstalk attenuation >120 dB prevents inter-channel interference |
| 7 | Inverting Input of Amp 2 | Functionally identical to Pin 2; supports dual-channel signal processing in single package |
| 8 | Non-Inverting Input of Amp 2 | Matches Pin 3 behavior; enables matched dual-path designs such as differential receivers |
Key Features
| Feature | Design Value |
|---|---|
| No external frequency compensation required | Internal dominant-pole compensation ensures unconditional stability at unity gain without added capacitors or resistors |
| Wide common-mode input voltage range | ±12 V operation allows direct connection to transducers and bridges without input attenuators or level shifters |
| Short-circuit protected outputs | Enables robust operation in test equipment and industrial interfaces where accidental shorts may occur |
| No latch-up behavior | Prevents destructive failure during overvoltage transients or improper power sequencing |
| Interchangeable with legacy MC1558/MC1458 variants | Same pinout and electrical behavior as Motorola/Signetics equivalents simplifies drop-in replacement in existing designs |
Applications
| Industrial Sensor Signal Conditioning | Audio Pre-Amplification Stage |
|---|---|
Use Scenario: Amplifying low-level millivolt outputs from RTDs, thermocouples, or strain gauges in PLC analog input modules. IC Role / Device Role / Timing Role: Dual-channel DC-coupled amplifier providing gain and buffering before ADC sampling. Use Value: ±12 V common-mode range accepts sensor signals referenced to system ground; 6 mV offset ensures <0.1% full-scale error in 12-bit systems. | Use Scenario: First-stage amplification of microphone or line-level signals prior to tone control and power amplification. IC Role / Device Role / Timing Role: Low-noise, unity-gain stable op-amp configured as non-inverting buffer and active filter driver.

IC Role / Device Role / Timing Role: Independent amplifiers performing gain, filtering, and level-shifting for parallel ADC inputs. Use Value: >120 dB crosstalk attenuation prevents coupling between channels; 0.5 V/μs slew rate handles step responses in closed-loop current regulation. | Use Scenario: Isolating and buffering precision voltage references (e.g., bandgap or DAC outputs) driving multiple downstream circuits. IC Role / Device Role / Timing Role: Unity-gain buffer minimizing source loading while maintaining DC accuracy and transient response. Use Value: High input impedance (>0.3 MΩ) avoids reference drift; short-circuit protection safeguards against accidental output faults. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual general-purpose operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DR | Single-supply rated (3–32 V), lower input offset (7 mV typ), no dual-supply symmetry | Better suited for battery-powered or 3.3 V/5 V microcontroller interfaces | Select when operating from single-ended rails or requiring rail-to-rail input capability |
| TL072CDR | Higher slew rate (13 V/μs), JFET input (50 pA bias current), wider bandwidth (3 MHz) | Preferred for higher-frequency AC signal paths and low-noise audio preamps | Choose for improved speed and noise performance where dual-supply operation is maintained |
Compared with LM358DR and TL072CDR, the MC1458DRE4 offers superior common-mode rejection (70–90 dB), guaranteed dual-supply symmetry, and proven long-term reliability in industrial environments - making it optimal for legacy-compatible, precision DC-coupled analog systems.

FAQ
What is the maximum operating temperature range for the MC1458DRE4?
The MC1458DRE4 is specified for operation from 0°C to 70°C ambient temperature. This range is defined in TI's SLOS069C datasheet under "Recommended Operating Conditions" and applies to all SOIC-packaged MC1458 variants including MC1458DRE4. Exceeding 70°C may degrade offset voltage drift and increase supply current beyond guaranteed limits.
Does the MC1458DRE4 require external compensation components?
No, the MC1458DRE4 does not require external compensation components. Its internal frequency compensation ensures stable unity-gain operation, as confirmed in the "Features" section of the SLOS069C datasheet. This eliminates the need for external capacitors or resistors in standard inverting, non-inverting, or voltage-follower configurations.
Is the MC1458DRE4 pin-compatible with the original Motorola MC1458?
Yes, the MC1458DRE4 is pin-compatible with the original Motorola MC1458. TI explicitly states in the datasheet that the MC1458 and MC1558 are "designed to be interchangeable with Motorola MC1558/MC1458", and the SOIC-D package maintains identical 8-pin layout and terminal functions as documented in the top-view pin diagram for MC1458 . . . D, P, OR PS PACKAGE.
What is the typical input bias current of the MC1458DRE4 at 25°C?
The typical input bias current of the MC1458DRE4 at 25°C is 80 nA, with a maximum of 500 nA across the full operating temperature range. This value is specified in the "Electrical Characteristics" table of SLOS069C under parameter IIB (Input Bias Current), confirming bipolar transistor input stage behavior consistent with μA741 architecture.
Can the MC1458DRE4 drive a 2 kΩ load effectively?
Yes, the MC1458DRE4 can drive a 2 kΩ load effectively. The datasheet specifies ±10 V maximum peak output voltage swing under RL = 2 kΩ conditions at 25°C, and short-circuit protection ensures safe operation even if the load approaches zero ohms. Output resistance is 75 Ω, supporting stable gain accuracy with moderate loads.
