NE5532APSRE4 - Dual 10MHz Low-Noise Op Amp | Texas Instruments
MPN: NE5532APSRE4 ✓ ActiveNE5532APSRE4 Overview
An operational amplifier is an analog integrated circuit that provides high open-loop gain and uses negative feedback to amplify, buffer, filter, or control voltage signals. Within the semiconductor hierarchy, the NE5532 belongs to the operational-amplifier, analog-amplifier, and signal-conditioning IC categories. It combines low voltage noise, high common-mode rejection, a 9 V/µs typical slew rate, and a 100 V/mV typical high DC voltage gain in a common surface-mount package.
Key features include two amplifier circuits, 10 MHz typical gain-bandwidth product, 5 nV/√Hz typical input noise at 1 kHz, 100 dB typical CMRR, and a 15 V typical or maximum supply figure identified in the retrieved specifications. The 8-SOIC package measures approximately 5.30 mm in width according to the distributor listing. Tape-and-reel ordering is identified by the E4 suffix, making the part suitable for standard automated surface-mount assembly and replenishment processes.
The device uses complementary input and output stages to deliver low-noise voltage amplification. Its unity-gain bandwidth makes it suitable for audio-frequency and moderate-bandwidth signal paths, while its high CMRR helps reject common-mode interference. The 9 V/µs slew rate supports reasonably rapid signal transitions. Designers should still verify output-voltage swing, input common-mode range, supply limits, and stability against their individual operating conditions before finalizing a circuit.
Typical applications include stereo audio preamplifiers, active crossover and equalization networks, microphone-level conditioning, test-equipment input buffers, low-frequency active filters, and general-purpose analog signal processing. One amplifier section may drive or process one audio channel, allowing the dual package to support stereo or balanced two-channel circuitry while reducing board area.
For stable operation, place the input, output, feedback, and compensation components close to the device and use a clean, low-impedance ground reference. Decoupling should follow the manufacturer datasheet recommendations. Avoid operating the amplifier at a gain where its internal compensation and board parasitics produce instability, and verify the common-mode input range whenever signals approach either supply rail.
This product page consolidates the verified 10 MHz bandwidth, noise, CMRR, slew-rate, package, temperature, and observed distributor pricing data with application guidance, engineering design notes, and drop-in replacement information.

Typical Applications
NE5532APSRE4 is suitable for 6 applications: Stereo Audio Preamplifier, Active Equalization and Crossover Network, Microphone and Instrumentation Preamp, Precision Active Filter, Test and Measurement Input Buffer, Audio Interface Output Driver.
Stereo Audio Preamplifier
The NE5532APSRE4 fits a stereo audio preamplifier because its 5 nV/√Hz typical input noise at 1 kHz supports a low input-referred noise floor, while its 100 dB typical common-mode rejection helps reduce interference coupled into audio lines. Each half of the dual 8-SOIC device can process one channel, reducing board area compared with separate single amplifiers. The 10 MHz typical unity-gain bandwidth provides margin for audio-band feedback networks. Engineers should still verify output swing into the intended load, confirm that input signals remain within the common-mode range, and account for the amplifier’s bias-current contribution when selecting source impedance.
Recommended
Active Equalization and Crossover Network
The NE5532APSRE4 is suitable for active audio equalization and crossover networks because its 9 V/µs typical slew rate and 10 MHz typical unity-gain bandwidth can support moderate-frequency closed-loop operation. Two independent amplifiers allow separate processing channels or complementary filter stages within one 8-SOIC package. Low input noise of 5 nV/√Hz is valuable when processing weak signals before an output stage. The bandwidth and noise-gain interaction of each R, C, and Cauer network must be calculated, since increasing noise gain reduces closed-loop bandwidth and can introduce phase margin concerns.
Recommended
Microphone and Instrumentation Preamp
The NE5532APSRE4 can serve as a microphone or instrumentation preamplifier when low input noise is more important than rail-to-rail input capability. Its 5 nV/√Hz typical equivalent input noise at 1 kHz provides a favorable starting point for low-level signal amplification, and the 100 dB typical common-mode rejection helps reject common-mode interference on balanced or shielded inputs. Designers should calculate the total input-referred noise using the source impedance, resistor network, and amplifier contribution. Input bias current of 1 µA must also be checked against source resistance to prevent avoidable offset error.
Recommended
Precision Active Filter
The NE5532APSRE4 is appropriate for precision active filters operating below its 10 MHz typical unity-gain bandwidth. Its high 100 V/mV typical open-loop DC gain supports accurate closed-loop amplification, while the 100 dB typical common-mode rejection can improve rejection of unwanted common-mode signals. Component tolerances and the amplifier’s finite gain-bandwidth product will determine filter accuracy and phase response. For higher-order filters, simulate gain and phase around the operating frequency, keep noise gain within the amplifier’s stable region, and place the sensitive high-impedance nodes away from switching nodes and digital return paths.
Recommended
Test and Measurement Input Buffer
The NE5532APSRE4 can buffer moderate-bandwidth test and measurement inputs because its 10 MHz typical unity-gain bandwidth and 9 V/µs typical slew rate provide useful speed for general-purpose instrumentation. The 5 nV/√Hz typical input noise is beneficial when buffering low-level signals, and the dual package permits separate handling of two channels or a gain stage plus output driver. Input protection, source impedance, and capacitive loading require separate evaluation. At the 10 MHz unity-gain limit, board layout and probe capacitance can materially affect stability, so short feedback traces and carefully placed compensation or termination components are important.
Recommended
Audio Interface Output Driver
The NE5532APSRE4 can be used in audio interface output-driver sections when the design requires low-noise voltage amplification before a conventional output stage. Its 100 dB typical common-mode rejection and 5 nV/√Hz typical input noise are useful in a balanced audio path, while the two amplifier channels can support complementary or dual-channel routing. The 9 V/µs typical slew rate is sufficient for many audio-frequency waveforms, but it does not imply unlimited load capability. The output-current demand, output-voltage swing, and thermal dissipation should be calculated against the selected load, especially when driving low-impedance headphone or line-stage networks.

- Broad bandwidth margin for general-purpose signal paths (vs OPA2604)
Design Notes
Route the feedback loop as a short, compact path around the amplifier, and place its compensation or frequency-setting components close to the relevant pins. Keep the non-inverting input and high-impedance feedback nodes away from switching nodes, clock lines, and connector-return paths. For the NE5532APSRE4, preserving a low-inductance ground reference is particularly important because the 10 MHz typical bandwidth can couple small layout discontinuities into measured noise or ringing.
Follow the manufacturer datasheet's supply-decoupling recommendations and place the input bypass capacitor directly between the supply and ground pins. Do not assume that the 15 V maximum supply rating permits unrestricted rail-to-rail input or output operation. Check the actual output swing against load current and the input common-mode range against signal amplitude. Estimated power dissipation should be calculated from the measured supply voltage, output voltage, and load current in the finished circuit.
Verify closed-loop stability at every intended gain, especially near the 10 MHz typical unity-gain bandwidth. Probe capacitance, long feedback traces, and source impedances can materially alter the response of a nominally general-purpose amplifier. For filters or cable drivers, simulate the complete network and evaluate phase margin across component tolerances. If the selected alternative changes noise gain or output impedance, repeat the stability analysis rather than relying only on package-pin compatibility.
Compliance Information
No explicit environmental-compliance declarations were present in the supplied verified data. The 0°C to 70°C rating indicates a commercial-temperature product, but it is not itself evidence of AEC-Q100 qualification.
