What are the key features of MC1458PE4?
- Dual op-amp channel integration in a single 8-pin DIP package reduces board space compared to two single op-amp ICs
- 90 dB typical common-mode rejection ratio (CMRR) enables accurate differential signal amplification in mixed-signal designs
- Internal frequency compensation simplifies circuit design by eliminating the need for external compensation capacitors
What is MC1458PE4 used for?
The MC1458PE4 is widely used in analog signal conditioning circuits, active filters, and summing amplifiers for general-purpose audio and instrumentation applications. Its dual-channel architecture suits differential amplifier configurations for sensor bridge interfaces where both channels must be closely matched. The through-hole DIP package makes it popular for prototyping, repair work, and legacy industrial equipment maintenance.

Frequently Asked Questions
How does the MC1458PE4 CMRR specification affect its accuracy in a difference amplifier configuration?
The MC1458PE4 provides a minimum CMRR of 70 dB and a typical value of 90 dB, meaning common-mode signals are attenuated by at least 3000× relative to differential signals. In a unity-gain difference amplifier processing a 1 V differential signal from a bridge sensor, the common-mode error contribution is at most 0.316 mV at 70 dB, which is sufficient for most general-purpose 8-bit to 10-bit accuracy requirements.
What is the input offset voltage of the MC1458PE4 and how does it limit precision DC applications?
The MC1458PE4 specifies a maximum input offset voltage of 6000 µV (6 mV) at 25°C with a maximum bias current of 0.8 µA. For closed-loop gains above 100, this offset is amplified to over 600 mV at the output, making the part unsuitable for precision DC amplification without external trimming. For audio and AC-coupled signal paths the DC offset is filtered away and does not affect performance.
For a legacy industrial PID controller board using through-hole components, how suitable is the MC1458PE4?
The MC1458PE4 in its 8-pin DIP package is a direct plug-in replacement for the classic LM1458 and μA1458 dual op amps, maintaining pin compatibility across the full 8-pin DIP footprint. Operating from ±15 V dual supplies typical in industrial analog PID controllers, it delivers adequate bandwidth for control loops at frequencies below 100 kHz, and its DIP form factor simplifies field servicing and prototype builds on standard 2.54 mm pitch breadboards.
How does internal frequency compensation in MC1458PE4 benefit a first-time analog designer building a Sallen-Key filter?
Internal frequency compensation in the MC1458PE4 sets the unity-gain bandwidth at approximately 1 MHz, making the op amp unconditionally stable for all closed-loop gains from unity upward. A Sallen-Key low-pass filter built with gains of 1–10 requires no external compensation capacitors, simplifying the design to only the passive RC network components and reducing the risk of oscillation that non-compensated op amps introduce.
