Product details
Overview
MC1458DE4 from Texas Instruments is a dual general-purpose operational amplifier, electrically similar to μA741 per amplifier half, with no offset null capability. It operates over 0°C to 70°C, delivers ±12 V output swing into 10 kΩ, features internal frequency compensation, and is short-circuit protected - used in industrial signal conditioning and analog sensor interface circuits.
For engineers reviewing the MC1458DE4 datasheet, MC1458DE4 pinout, MC1458DE4 application, or MC1458DE4 equivalent, this page provides verified electrical specs, SOIC-8 package details, dual op-amp functional context, thermal limits, and validated alternative parts for legacy design continuity and sourcing resilience.
Technical Context
The MC1458DE4 integrates two independent high-input-impedance op-amps sharing a common ±15 V supply. Each amplifier exhibits 1 MHz unity-gain bandwidth, 65° phase margin, and 14 kHz full-swing closed-loop bandwidth at AVD = 1 - enabling stable voltage-follower and basic gain-stage configurations without external compensation.
Its wide common-mode input range (±12 V), absence of latch-up, and short-circuit protection support robust operation in unregulated or noisy supply environments. Input bias current (80–500 nA) and offset voltage (1–6 mV) are specified across temperature, confirming suitability for DC-coupled instrumentation front-ends where moderate precision suffices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±15 V - supports standard bipolar analog rails; 30 V total span enables compatibility with legacy ±12 V systems. |
| Input Offset Voltage | 1–6 mV at 25°C - defines minimum resolvable DC signal; impacts accuracy in low-gain amplification or summing applications. |
| Large-Signal Voltage Gain | 15–200 V/mV (15,000–20,000 V/V) - ensures high open-loop gain for precise closed-loop gain setting with feedback resistors. |
| Output Swing | ±10 V into 2 kΩ, ±12 V into 10 kΩ - determines usable dynamic range before clipping in buffer or amplifier stages. |
| Slew Rate | 0.5 V/μs - limits maximum undistorted sinusoidal output frequency at given amplitude; e.g., ~80 kHz for 10 Vpp. |
| Input Resistance | 0.3–2 MΩ - sets loading effect on high-impedance sources such as piezoelectric sensors or passive filters. |
| Common-Mode Rejection | 70–90 dB - suppresses noise coupled equally to both inputs, critical in differential measurement setups. |
Pinout & Package
MC1458DE4 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package, 3.9 mm wide, 4.9 mm long, 1.75 mm max height, RoHS-compliant with NiPdAu lead finish and Moisture Sensitivity Level 1 (unlimited floor life at ≤30°C/60% RH).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output of Amplifier 1 | Delivers amplified signal; capable of ±25 mA short-circuit current; requires load decoupling for stability. |
| 2 | Inverting Input of Amplifier 1 | Accepts feedback or signal source; high-impedance node sensitive to PCB leakage and stray capacitance. |
| 3 | Non-Inverting Input of Amplifier 1 | Reference or signal input; common-mode range extends to ±12 V, enabling rail-to-rail input operation within supply limits. |
| 4 | Negative Supply (VCC−) | Ground reference for negative rail; must be connected directly to low-impedance return path to minimize noise coupling. |
| 5 | Positive Supply (VCC+) | Power rail for both amplifiers; bypassing with 0.1 µF ceramic capacitor near pin improves PSRR and transient response. |
| 6 | Output of Amplifier 2 | Independent output stage; crosstalk attenuation ≥120 dB ensures minimal interaction between channels. |
| 7 | Inverting Input of Amplifier 2 | Functionally identical to Pin 2; layout symmetry recommended to match parasitics across both halves. |
| 8 | Non-Inverting Input of Amplifier 2 | Functionally identical to Pin 3; shared supply rails enable correlated power-supply rejection between amplifiers. |
Key Features
| Feature | Design Value |
|---|---|
| No external frequency compensation required | Internally compensated for unity-gain stability - eliminates need for external capacitor, reducing BOM count and board area. |
| Short-circuit protected outputs | Unlimited duration short-circuit tolerance to either rail - enables safe operation during prototyping, fault conditions, or relay-driven loads. |
| Wide common-mode input range | ±12 V at ±15 V supply - allows direct interfacing with signals referenced to system ground without level-shifting circuitry. |
| No latch-up behavior | Immune to CMOS-like destructive latch-up - ensures reliability in mixed-signal systems with digital switching noise. |
| Low power consumption | 3.4–5.6 mA total supply current - supports thermally constrained designs and battery-backed analog subsystems. |
Applications
| Industrial Sensor Signal Conditioning | Audio Pre-Amplification Stage |
|---|---|
Use Scenario: Amplifying low-level DC-coupled outputs from RTDs, strain gauges, or thermocouples in PLC analog input modules. IC Role / Device Role / Timing Role: Dual op-amp configured as precision non-inverting amplifier and active low-pass filter. Use Value: ±12 V output swing and 70 dB CMRR reject common-mode noise from 4–20 mA loop interference. |
Use Scenario: Boosting microphone-level signals (–60 dBV) to line-level (−10 dBV) in legacy audio mixing consoles. IC Role / Device Role / Timing Role: First-stage preamp with gain of 100 V/V and 20 Hz–20 kHz bandwidth. Use Value: 0.5 V/μs slew rate prevents slew-induced distortion at 1 kHz/10 Vpp; low input bias avoids capacitor discharge in AC-coupled inputs. |
| DC Motor Speed Reference Buffer | Analog Voltage Comparator Interface |
Use Scenario: Isolating and buffering PWM-derived analog speed references in motor drive control boards. IC Role / Device Role / Timing Role: Unity-gain voltage follower driving 10 kΩ DAC output into optocoupler input. Use Value: High input impedance (>300 kΩ) prevents loading of RC-filtered PWM; short-circuit protection survives optocoupler LED faults. |
Use Scenario: Converting slow-varying process signals (e.g., pH sensor output) into clean logic-level transitions for microcontroller ADC triggering. IC Role / Device Role / Timing Role: Open-loop comparator with hysteresis added via feedback resistor network. Use Value: 1 MHz unity-gain bandwidth ensures sub-microsecond response to 100 mV step changes; no frequency compensation simplifies hysteresis design. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DR | Lower input offset (2–7 mV), higher supply current (0.7–1.2 mA per amp), rail-to-rail output not supported. | Better DC accuracy but reduced output swing (±1.5 V less than MC1458DE4 at ±15 V); optimized for single-supply use. | Select LM358DR when operating from +5 V/+12 V only and DC offset is critical; avoid if ±15 V bipolar operation is required. |
| TL072CDR | Higher slew rate (13 V/μs), lower input bias (30 pA), JFET input, no short-circuit protection. | Superior AC performance and noise immunity, but vulnerable to output shorts; requires external current limiting. | Choose TL072CDR for audio or high-frequency filtering where speed and low noise outweigh fault tolerance needs. |
Compared with LM358DR and TL072CDR, MC1458DE4 offers balanced trade-offs: bipolar input stage with proven short-circuit resilience, stable ±15 V operation, and legacy footprint compatibility - making it optimal for industrial analog signal chains requiring field-proven robustness over cutting-edge specs.

FAQ
What is the maximum operating temperature range for MC1458DE4?
The MC1458DE4 is rated for operation from 0°C to 70°C ambient temperature. This commercial-grade specification aligns with its PDIP and SOIC packaging variants and matches the recommended operating conditions defined in the TI SLOS069C datasheet. Exceeding 70°C may degrade offset voltage drift and increase supply current beyond guaranteed limits.
Does MC1458DE4 require external frequency compensation components?
No, MC1458DE4 does not require external frequency compensation components. It features internal compensation optimized for unity-gain stability across its full operating range. This eliminates the need for external capacitors or resistors in standard inverting/non-inverting configurations, simplifying layout and improving reliability in fixed-gain analog stages.
Can MC1458DE4 replace μA741 in existing designs?
MC1458DE4 can replace μA741 in dual-amplifier configurations, as each half is electrically similar to μA741 - except MC1458DE4 lacks offset null pins. For single-amplifier circuits, one half of MC1458DE4 functions equivalently to μA741, provided the PCB layout accommodates the 8-pin SOIC footprint and unused amplifier is properly terminated.
What is the input common-mode voltage range of MC1458DE4?
The input common-mode voltage range of MC1458DE4 is ±12 V when operated at ±15 V supply. This allows inputs to swing within 3 V of either rail, supporting direct connection to signals referenced to system ground without level-shifting. At lower supplies (e.g., ±5 V), the range scales proportionally per datasheet specifications.
Is MC1458DE4 pin-compatible with MC1458P or MC1458DR?
Yes, MC1458DE4 is pin-compatible with MC1458P (PDIP-8) and MC1458DR (SOIC-8), sharing identical 8-pin dual-in-line pinout: Pin 1 (1OUT), Pin 2 (1IN−), Pin 3 (1IN+), Pin 4 (VCC−), Pin 5 (VCC+), Pin 6 (2OUT), Pin 7 (2IN−), Pin 8 (2IN+). Footprint conversion between packages requires only land pattern adjustment, not schematic changes.
