NE5532APS - Dual 10MHz Low-Noise Op Amp | Texas Instruments
MPN: NE5532APS ✓ פעילNE5532APS סקירה
An operational amplifier is an analog integrated circuit that uses high-gain differential amplification to increase the difference between two input voltages. Operational amplifiers belong to the amplifier IC hierarchy and are commonly used in audio, control, measurement, and signal-processing circuits. The NE5532 family emphasizes low-noise performance, wide bandwidth, and practical dual-channel integration for applications requiring two similar amplifier functions in one package.
The NE5532APS combines a 10 MHz gain-bandwidth product with a slew rate of 9 V/µs. Its specified supply range of ±5 V to ±15 V accommodates conventional bipolar analog rails, including ±12 V and ±15 V systems. The NE5532x grade is specified for operation from 0°C to 70°C, while the electrically related SA5532x family extends the operating range from -40°C to +85°C. The NE5532APS is packaged for surface-mount assembly in an 8-pin SOP configuration.
Each internal amplifier has a differential input stage, a high-gain intermediate stage, and a push-pull output stage. The two amplifiers share supply pins but otherwise provide independent signal paths, allowing one device to implement stereo audio channels, balanced differential functions, active filtering, or a combination of buffering and gain. Stable operation around the unity-gain frequency and its 10 MHz bandwidth make it suitable for audio-frequency amplification and feedback networks.
Typical uses include stereo audio preamplification, microphone preamplifiers, active crossover filters, line-level buffers, tone controls, and small-signal audio stages. It can also support low-frequency measurement or instrumentation circuits when the input signal remains within its common-mode and output-voltage limits. In each case, external resistor and capacitor networks determine the actual gain, bandwidth, and filtering response.
The main design consideration is power-rail compatibility. The device expects bipolar supplies within ±5 V to ±15 V and does not operate from a single 5 V rail under its specified conditions. Designers should preserve input and output headroom, avoid excessive capacitive loading at the output, and select external feedback values that keep the closed-loop bandwidth and stability appropriate for the intended signal.
This page combines the manufacturer’s device specifications with package details, sourcing guidance, application guidance, and an engineering-focused review of replacement considerations. It also distinguishes genuine pin-compatible options from devices that merely provide similar audio performance, helping designers avoid changes that require PCB or signal-path redesign.

Stereo Audio Preamplifier
The NE5532APS is suitable for a stereo small-signal preamplifier because it integrates two amplifiers with a 10 MHz gain-bandwidth product and 9 V/µs slew rate. Each channel can implement its own gain and feedback network while the device operates from conventional ±5 V to ±15 V rails. The dual arrangement reduces the number of amplifier packages and simplifies channel pairing. Place a close decoupling network at pin 8 and pin 4, keep input and output traces away from switching nodes, and verify that the programmed gain leaves adequate output swing for the intended source level.
Microphone Preamplifier
The NE5532APS can amplify a low-level microphone signal in a low-noise audio channel when the external feedback network and source impedance are designed carefully. Its 10 MHz gain-bandwidth product provides bandwidth beyond the audio band, while the dual structure permits one amplifier for the microphone path and the other for a subsequent buffer or gain stage. The specified ±5 V to ±15 V supply range suits many professional and consumer audio systems. Confirm the maximum input bias current, noise density, common-mode range, and output swing against the microphone and downstream circuitry before production use.
Active Crossover and Filter
The NE5532APS is a practical choice for active crossover, equalizer, and tone-control networks that use two amplifier channels. Its 10 MHz gain-bandwidth product and 9 V/µs slew rate allow the closed-loop amplifiers to handle audio-band signals with useful bandwidth margin. The device operates from ±5 V to ±15 V, matching many dual-rail analog systems. Component tolerances and the op amp’s gain-bandwidth behavior contribute to the filter response, so calculate the R and C networks against the desired cutoff and Q, then verify channel matching and stability on the assembled board.
Audio Line Buffer
The NE5532APS can buffer two audio line signals when a source would otherwise load the preceding stage. Buffering with a dual operational amplifier preserves channel symmetry and avoids using both halves of the device for unrelated high-gain functions. The 10 MHz gain-bandwidth product is substantially wider than standard audio-band signals, and the 9 V/µs slew rate supports clean transitions through the intended signal range. Operate the device from ±5 V to ±15 V, maintain sufficient output-voltage headroom, and avoid placing a large capacitive load directly on either output unless stability has been evaluated.
Mixer and Summing Amplifier
The NE5532APS can form the summing or mixing stage of a small analog mixer using its two internal amplifiers. With a 10 MHz gain-bandwidth product and 9 V/µs slew rate, it can support multiple audio inputs when the closed-loop gain and source impedances are selected appropriately. Its specified bipolar supply range of ±5 V to ±15 V allows integration with traditional audio circuitry. Keep each summing node appropriately terminated, account for the amplifier input bias current when selecting resistors, and confirm that summed signal peaks remain inside the output-voltage and common-mode limits.
Instrumentation and Low-Level Signal Conditioning
The NE5532APS can condition low-level signals in instrumentation, test, and measurement circuits when the required bandwidth and noise performance fall within its limits. The two amplifiers can be used for independent input-conditioning or differential functions, while the 10 MHz gain-bandwidth product supports feedback networks beyond the base audio range. The NE5532x grade is specified from 0°C to 70°C, making it appropriate for commercial ambient conditions rather than extended industrial temperatures. Confirm offset voltage, bias current, common-mode range, and output swing before using it for precision measurement chains.

הערות תכנון
Decouple the positive and negative supply pins close to the package with a compact ceramic bypass capacitor and a suitable bulk capacitor. The NE5532APS is specified for ±5 V to ±15 V, so verify rail polarity and total voltage before power-up. Keep the return path from the bypass capacitors short and avoid sharing high-current return paths with sensitive audio inputs, since supply impedance can convert load currents into voltage noise at the amplifier pins.
Assign pin 1 and pin 7 to the two amplifier outputs, keep the two channels physically separated where practical, and route non-inverting inputs away from output and supply traces. Feedback components should sit close to their associated input pins to minimize parasitic coupling and add unwanted high-frequency feedback. For the 8-pin SOP footprint, follow the manufacturer’s land pattern and pin-1 orientation rather than relying only on a generic package drawing.
Do not treat the NE5532 family as a single-supply 5 V device or substitute a DIP-package NE5532 variant without changing the PCB footprint. Check the closed-loop gain, output swing, and common-mode limits against the actual signal. Also review the maximum capacitive load before driving long cables, connectors, or other stages directly, because unstable behavior can result from output loading even when the bandwidth and slew-rate figures appear adequate.
