Product details
Overview
MC1458DRG4 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 industrial signal conditioning and analog sensor interfaces.
For engineers reviewing the MC1458DRG4 datasheet, MC1458DRG4 pinout, MC1458DRG4 application, or MC1458DRG4 equivalent, this page delivers verified electrical parameters, thermal limits, real-world use cases, and validated alternative options for legacy analog design continuity and component obsolescence mitigation.
Technical Context
The MC1458DRG4 implements two independent high-input-impedance op-amp channels electrically similar to μA741 but without offset null pins. Its wide common-mode input range (±12 V) and absence of latch-up support robust voltage-follower configurations across temperature extremes.
Internally compensated for unity-gain stability, it delivers 1 MHz unity-gain bandwidth, 0.5 V/μs slew rate, and 14 kHz full-power bandwidth into 2 kΩ loads - all while drawing only 3.4–5.6 mA total supply current under ±15 V operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±5 V to ±15 V - supports standard bipolar rail systems without external regulation |
| Input Offset Voltage | ≤6 mV at 25°C - sets DC accuracy limit in precision gain stages and active filters |
| Common-Mode Input Range | ±12 V - enables direct interfacing with ±10 V industrial sensors and DAC outputs |
| Unity-Gain Bandwidth | 1 MHz - sufficient for audio-band amplification and low-speed control loop compensation |
| Slew Rate | 0.5 V/μs - constrains maximum undistorted output swing at 20 kHz for 10 Vpp signals |
| Short-Circuit Protection | Unlimited duration - allows safe operation during transient overloads or wiring faults |
| Operating Temperature | 0°C to 70°C - qualified for commercial-grade embedded instrumentation and test equipment |
Pinout & Package
MC1458DRG4 uses an 8-pin SOIC (D) package with 1.27 mm pitch, 3.91 mm width, and 4.9 mm length - compatible with standard surface-mount reflow profiles (MSL Level-1, 260°C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output of Amplifier 1 | Provides buffered, low-impedance output for driving 2 kΩ+ loads |
| 2 | Inverting Input of Amplifier 1 | Accepts feedback network connection for closed-loop gain configuration |
| 3 | Non-Inverting Input of Amplifier 1 | Connects to reference or sensor signal source with high-impedance bias path |
| 4 | Negative Supply (VCC−) | Reference return for dual-rail operation; must be decoupled near device |
| 5 | Positive Supply (VCC+) | Primary power rail; requires local 0.1 μF ceramic bypass capacitor |
| 6 | Output of Amplifier 2 | Independent output channel supporting dual-path signal processing |
| 7 | Inverting Input of Amplifier 2 | Enables second closed-loop stage without cross-channel coupling |
| 8 | Non-Inverting Input of Amplifier 2 | Supports differential pair or dual-sensor interface topologies |
Key Features
| Feature | Design Value |
|---|---|
| No external frequency compensation required | Guarantees unity-gain stability without added capacitors or resistors |
| Wide common-mode input voltage range | ±12 V enables direct connection to ±10 V transducer outputs without level-shifting |
| Short-circuit protected outputs | Eliminates need for external current-limiting resistors in fault-prone environments |
| No latch-up behavior | Ensures reliable recovery after input overvoltage or power sequencing anomalies |
| Low power consumption | 3.4–5.6 mA total supply current supports thermally constrained PCB layouts |
Applications
| Industrial Sensor Signal Conditioning | Audio Pre-Amplification |
|---|---|
Use Scenario: Amplifying low-level outputs from strain gauges, RTDs, or thermocouples in PLC analog input modules. IC Role / Device Role / Timing Role: Dual-channel DC-coupled amplifier providing gain, buffering, and common-mode rejection before ADC sampling. Use Value: ±12 V common-mode range accepts unconditioned sensor bridges; short-circuit protection prevents field-wiring faults from damaging downstream circuitry. | Use Scenario: Boosting microphone or line-level signals prior to analog-to-digital conversion in portable audio recorders. IC Role / Device Role / Timing Role: Low-noise, unity-gain stable voltage follower and non-inverting amplifier stage.

IC Role / Device Role / Timing Role: High-input-impedance comparator front-end and error amplifier in analog PID loops. Use Value: No latch-up ensures recovery from back-EMF transients; ±15 V supply headroom supports 12 V motor drive rails. |
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 (2 mV typ), no dual-rail symmetry | Better suited for battery-powered or single-rail systems; lacks true bipolar input range | Select when operating from +5 V or +12 V only, and offset voltage is critical |
| TL072CDR | JFET-input (50 pA bias current), higher slew rate (13 V/μs), wider bandwidth (3 MHz) | Superior for high-frequency AC coupling, low-noise audio, or high-Z source buffering | Select when sourcing from photodiodes, piezoelectric sensors, or high-impedance potentiometers |
Compared with LM358DR and TL072CDR, the MC1458DRG4 provides guaranteed bipolar rail operation, proven latch-up immunity, and legacy system compatibility - making it the preferred choice for repairing or maintaining existing ±15 V analog infrastructure where parameter drift and long-term reliability are prioritized over raw speed or ultra-low bias current.

FAQ
What is the maximum supply voltage rating for MC1458DRG4?
The MC1458DRG4 has an absolute maximum supply voltage rating of ±18 V. Operation within the recommended range of ±5 V to ±15 V ensures specified performance across the full 0°C to 70°C temperature range. Exceeding ±18 V risks permanent damage, and sustained operation near absolute maximums may reduce long-term reliability.
Does MC1458DRG4 include offset null pins?
No, the MC1458DRG4 does not provide offset null pins. Unlike the μA741, each amplifier section omits dedicated null adjustment terminals - simplifying layout but requiring external trimming if sub-millivolt DC accuracy is needed. The datasheet specifies a maximum input offset voltage of 6 mV at 25°C.
Is MC1458DRG4 pin-compatible with the original Motorola MC1458?
Yes, MC1458DRG4 is functionally and pin-compatible with the Motorola MC1458 and other industry equivalents including Signetics S5558. It maintains identical pinout, electrical behavior, and SOIC-8 footprint - enabling drop-in replacement in legacy designs originally specifying those parts.
What thermal considerations apply to MC1458DRG4 in continuous operation?
MC1458DRG4 has a junction-to-ambient thermal resistance (θJA) of 97°C/W in the SOIC (D) package. At ±15 V supply and 5.6 mA total supply current, power dissipation reaches ~168 mW - resulting in ~16°C junction rise above ambient. Adequate PCB copper area and airflow ensure safe operation below the 150°C maximum virtual junction temperature.
Can MC1458DRG4 drive capacitive loads directly?
The MC1458DRG4 is not optimized for heavy capacitive loading. While stable under unity-gain conditions with resistive loads, driving >100 pF directly may cause peaking or oscillation. For capacitive loads exceeding 100 pF, add a small series resistor (e.g., 22–100 Ω) between output and load to isolate capacitance and preserve phase margin.
