MC1458ID - Dual High-Performance Operational Amplifier | STMicroelectronics
MPN： MC1458ID ✗ 停產MC1458ID 概覽
An operational amplifier is a voltage-feedback analog amplifier used to amplify the difference between two input voltages. In a feedback network, the MC1458ID can provide high closed-loop gain, signal buffering, impedance transformation, and active-filter functions. Its dual-circuit architecture places two independent amplifiers in one package, reducing board area when a design requires two analog signal channels.
The MC1458ID is described as a high-performance monolithic dual operational amplifier with low power consumption and a large input-voltage range. The device also features high gain, short-circuit protection, no-latch-up behavior, and operation without frequency compensation. These characteristics make it suitable for instrumentation, audio signal processing, active filtering, summing and integrating circuits, and general analog control systems.
The MC1458ID uses a conventional dual-amplifier architecture rather than a digitally controlled or precision-specialty amplifier. Its two channels are packaged in an 8-SOIC, allowing a compact surface-mount implementation. The wide operating-voltage capability supports varied analog supply conditions, while the low-noise designation is relevant to applications in which signal integrity and small-signal amplification matter.
Typical uses include audio preamplification, instrumentation buffering, active filters, summing amplifiers, integrators, voltage followers, and function-generator circuits. In an instrumentation application, the device can buffer sensor outputs before conversion or further processing. In audio systems, one channel may process one signal path while the second handles another, provided the power supply and grounding arrangement support both circuits.
When designing around the MC1458ID, use the manufacturer pin-description table to assign supply, input, and output connections, and observe the dual-amplifier decoupling requirements. Place bypass capacitors close to the supply pins, keep feedback-loop routing short, and check input and output signal limits against the device operating conditions before finalizing the board layout.

典型應用
MC1458ID 適用於 6 應用s: Audio Signal Conditioning, Instrumentation Buffering, Active Filter Design, Summing Amplifier, Integrator and Control Loop, Function Generator.
Audio Signal Conditioning
The MC1458ID fits general-purpose audio amplification and buffering because it combines two low-noise operational-amplifier circuits in one 8-SOIC package. One channel can condition a left audio path while the second handles a right path, reducing component count and simplifying board layout. The amplifier can sit between a source and a downstream mixer, headphone circuit, or measurement chain. Designers should keep feedback traces short, decouple the supply near the device, and verify output swing, bandwidth, and distortion against the actual signal level before production.
推薦
Instrumentation Buffering
The MC1458ID is appropriate for buffering sensor and instrumentation outputs where two related analog channels need independent amplification. Its high-gain voltage-feedback architecture can reduce loading of a preceding sensor or divider network before signals reach an ADC or controller. The two channels are integrated in a compact 8-SOIC, which helps keep analog routing orderly. Check common-mode range and output swing for the actual sensor excitation, and route the ground return directly to the device to avoid adding noise or instability.
推薦
Active Filter Design
The MC1458ID can implement active filters because the manufacturer identifies summing amplifiers, voltage followers, active filters, and function generators as intended uses. Two amplifier sections allow a filter or filter-and-buffer architecture to be assembled with fewer separate packages. The external resistor and capacitor network determines the nominal response, while the amplifier’s gain and frequency behavior determine how closely the circuit follows the intended transfer function. Validate tolerances, noise, and stability in the final layout rather than relying only on nominal values.
推薦
Summing Amplifier
The MC1458ID is explicitly suited to summing-amplifier circuits, where multiple input signals are combined through a feedback network. The dual package can implement a main summing amplifier and a follow-up buffer or channel-balancing stage. This arrangement is useful in audio mixers, sensor-combination circuits, test fixtures, and control-signal generation. Select the feedback resistors for the intended gain and scaling, confirm that input and output remain within the device limits, and place the feedback network close to the relevant pins for predictable behavior.
推薦
Integrator and Control Loop
The MC1458ID supports integrator-type analog control loops because it is identified for integrator applications. One channel can integrate a control or measurement error signal while the other provides buffering or auxiliary gain. Integrator stability depends on the feedback capacitor, leakage, reset path, and the selected operating frequency, so those values should be reviewed against the datasheet. Keep the input and feedback components physically close and provide a defined reference point to prevent drift or saturation during startup.
推薦
Function Generator
The MC1458ID is listed for function-generator applications, making it suitable for simple analog oscillator and waveform-shaping circuits. Its two amplifier channels can be arranged for a signal-generating section and a supporting buffer or shaping stage. The operating frequency, amplitude, and distortion are determined by the external timing and feedback network as well as the amplifier characteristics. Validate the complete circuit across the intended frequency range and ensure the output does not exceed the device’s operating limits.

主要差異化特點

- No external frequency-compensation requirement (對比MC1458CD)
設計說明
Place the supply bypass capacitor close to the MC1458ID positive and negative supply pins. Keep the ground return short and use the package ground pin as the local reference. Check the complete manufacturer datasheet for the allowed supply range and current limits before selecting the regulator. The device is described as a low-power-consumption dual amplifier, but actual board consumption depends on supply voltage, load, and channel activity.
Route each feedback loop as a short, compact connection between the relevant output and input pins. Place feedback resistors and capacitors close to the amplifier pins rather than around the board perimeter. This reduces parasitic capacitance and resistance that can alter active-filter response, integrator behavior, and stability. Maintain a direct ground path for both amplifier channels.
Do not treat a generic dual-op-amp pin diagram as a substitute for the MC1458ID pin-description table. Confirm amplifier-channel assignments, supply pins, and any offset-adjustment connections in the manufacturer datasheet. Also verify the input range and output swing at the intended supply voltage. The device’s wide input-voltage capability and no-latch-up feature do not remove the need to check operating limits.
