NE5532ADR - 30V, 10MHz Dual Low-Noise Op Amp | Texas Instruments
料号： NE5532ADR ✓ 量产中NE5532ADR 概述
An operational amplifier is a voltage-feedback amplifier whose open-loop gain is used to create closed-loop gain with external feedback components. The low-noise operational amplifier category is part of the broader analog signal-processing hierarchy: operational amplifier, analog IC, and semiconductor. NE5532-family devices became established choices in audio circuitry because they combine low input noise, adequate bandwidth, high slew rate, and wide supply-voltage capability in a conventional through-hole-compatible or surface-mount package.
Key verified attributes include a 30 V maximum supply rating, dual-amplifier configuration, 10 MHz bandwidth, 9 V/µs slew rate, and operation over ±5 V to ±15 V. According to the Texas Instruments manufacturer datasheet, the NE5532x grade is specified from 0°C to 70°C, while the electrically similar SA5532x grade extends the operating range to -40°C to +85°C. These distinctions matter when selecting between commercial-temperature and industrial-temperature versions.
The NE5532ADR uses the standard dual-operational-amplifier arrangement, allowing each amplifier to be configured independently for non-inverting, inverting, summing, filtering, or active-amplifier functions. Its 8-pin SOIC package supports compact, surface-mount PCB construction while preserving a conventional dual-op-amp footprint. Designers should still verify output-current, output-voltage swing, input-bias-current, noise-density, and open-loop-gain requirements against the complete manufacturer electrical-characteristics tables.
Typical applications include stereo audio preamplifiers, active crossover filters, microphone preamplifiers, line-level mixers, and small-signal audio output stages. Its 10 MHz bandwidth is well above the audible band, while its low-noise designation makes it appropriate for amplifying weak audio signals without adding unnecessary broadband noise. The 9 V/µs slew rate also helps preserve low distortion when processing larger transient waveforms.
The primary design consideration is power-supply configuration. The manufacturer datasheet specifies operation from ±5 V to ±15 V, and dual-supply operation generally simplifies bipolar audio-signal handling around ground. Designers must observe the output-swing limits, avoid excessive capacitive loading, and maintain suitable decoupling close to the supply pins. Stable feedback networks and appropriately chosen compensation or load conditions are important for reliable closed-loop operation.
This page combines verified manufacturer and distributor information with pinout guidance, practical application fit, drop-in comparison data, and engineering-focused selection notes. The comparison also distinguishes true pin-compatible options from devices that may sound different or require different supply and stability considerations.

典型应用
NE5532ADR 适用于 6 应用s: Stereo Audio Preamplifier, Active Audio Crossover, Microphone Preamplifier, Line-Level Audio Mixer, Audio DAC Output Buffer, Instrumentation Signal Conditioning.
Stereo Audio Preamplifier
The NE5532ADR fits stereo audio preamplification because it provides two low-noise amplifiers, a 10 MHz gain-bandwidth product, and a 9 V/µs slew rate in one 8-pin SOIC package. Each channel can use the conventional non-inverting or inverting topology while preserving the same pin arrangement used by many legacy audio boards. According to the Texas Instruments manufacturer datasheet, the NE5532 is intended specifically for audio applications and operates from ±5 V to ±15 V. The dual 10 MHz bandwidth provides substantial margin over the audio band, while the specified slew rate helps control distortion on larger transients. Designers should still check output swing, load capability, and noise-gain stability in the complete preamplifier rather than assuming that the headline bandwidth alone guarantees distortion performance.
推荐
Active Audio Crossover
The NE5532ADR is suitable for active crossover networks because its 10 MHz gain-bandwidth product supports the precision-feedback networks commonly used in low-pass, high-pass, and band-pass filters. The 9 V/µs slew rate helps each amplifier reproduce transitions without excessive slew-related distortion, while the low-noise designation is useful when the filter processes a weak source signal directly. The dual amplifier can implement two closely related filter channels or separate channels for stereo operation. According to the Texas Instruments manufacturer datasheet, operation is specified from ±5 V to ±15 V, which supports conventional bipolar audio signal paths. Component tolerances, op-amp gain-bandwidth behavior, and allowable capacitive loading should be evaluated together to maintain filter stability and the intended cutoff and phase response.
推荐
Microphone Preamplifier
The NE5532ADR can serve as a low-noise microphone preamplifier when the source impedance and signal level are compatible with the device’s input characteristics. Its low-noise operational-amplifier designation reduces the likelihood of adding unnecessary broadband noise ahead of later amplification, while the 10 MHz gain-bandwidth product provides useful bandwidth margin for microphone and line-level circuitry. According to the Texas Instruments manufacturer datasheet, the amplifier operates from ±5 V to ±15 V and is explicitly aimed at audio applications. A practical implementation should include input biasing, coupling or DC-servo arrangements as appropriate, and protection against accidental microphone insertion transients. Because the supplied data does not quantify input-noise density, input bias current, or input-voltage range, those values must be checked in the manufacturer electrical-characteristics table before setting the actual gain.
推荐
Line-Level Audio Mixer
The NE5532ADR is appropriate for a line-level mixer built around summing and inverting amplifier stages because it combines two amplifiers, 10 MHz bandwidth, and 9 V/µs slew rate in a compact 8-pin SOIC. The faster slew rate relative to audio frequencies can reduce distortion when multiple signals combine, provided the feedback network remains stable and the output does not exceed the device’s swing limits. According to the Texas Instruments manufacturer datasheet, the part is specified for ±5 V to ±15 V operation and intended for audio use. Designers should include adequate supply bypassing, maintain conservative gains, and calculate resistor-network impedance carefully because the supplied verification data does not provide a confirmed input-bias-current value. Stable passive feedback networks are especially important when several mixer branches are connected together.
推荐
Audio DAC Output Buffer
The NE5532ADR can buffer a stereo audio DAC output when the required signal amplitude and loading remain within the amplifier’s limits. Its 10 MHz gain-bandwidth product and 9 V/µs slew rate are well above the nominal audio range, allowing the device to preserve small-signal fidelity while isolating the DAC from the next mixer or line-output stage. According to the Texas Instruments manufacturer datasheet, the NE5532 family is designed for audio applications and supports ±5 V to ±15 V supplies. The same 8-pin SOIC footprint used in many legacy audio designs simplifies board upgrades, but output swing, load stability, and channel-to-channel behavior must be checked in the complete output network. Power-supply decoupling and short feedback traces are essential for preserving low distortion.
推荐
Instrumentation Signal Conditioning
The NE5532ADR can be used for small-signal instrumentation conditioning when its verified operating range, bandwidth, and slew rate satisfy the circuit requirements. The 10 MHz gain-bandwidth product is useful for sensor and test-signal amplification beyond the audio band, while the 9 V/µs slew rate supports rapidly changing waveforms. According to the Texas Instruments manufacturer datasheet, the device is specified for ±5 V to ±15 V and includes a commercial-temperature NE5532x grade from 0°C to 70°C. Instrumentation users should not automatically interpret the audio-device designation as precision performance: input offset, bias current, open-loop gain, common-mode range, and noise specifications are not provided in the verified search data and must be confirmed before precision measurements. SA5532ADR is the same-footprint option when an extended-temperature range is required.

关键差异点
- Audio-focused dual-amplifier configuration （对比 NE5534DR)
- Extended-temperature same-family option （对比 SA5532ADR)
- Established standard SOIC-8 footprint （对比 AD823ARZ)
- Documented 10 MHz bandwidth and 9 V/µs slew rate （对比 OPA2134UA)
设计说明
The Texas Instruments manufacturer datasheet specifies ±5 V to ±15 V operation for NE5532ADR, with a 30 V maximum total supply. Confirm that both positive and negative rails remain within their limits during power-up and shutdown. Place the positive-rail bypass capacitor close to pin 8 and the negative-rail bypass close to pin 4, and account for supply-current variation across both amplifier channels. The verified data does not include current-consumption limits, so use the datasheet before calculating regulator headroom.
Keep the SOIC-8 footprint compatible with the standard dual-op-amp arrangement when creating a drop-in board revision. Route pins 2, 3, 5, and 6 as sensitive inputs, keep their traces short, and isolate them from switching-regulator and digital-clock nodes. Use a ground reference that remains low-impedance from pin 4 to the supply return. The verified NE5534DR site-MPN option is useful for same-family board evaluation, but its different output-drive characteristics must be checked before substituting it.
Do not treat identical 8-pin SOIC packaging as proof of identical behavior. OPA2134UA, OPA2604UA, and AD823ARZ may have different noise, distortion, slew rate, output swing, gain-bandwidth products, and stability behavior. Before replacing NE5532ADR, compare the closed-loop gain, output load, source impedance, supply rails, and capacitive loading against each alternative’s complete data. Also note that SA5532ADR provides -40°C to +85°C operation, while NE5532ADR is the 0°C to +70°C grade.
For audio preamplifiers and active filters, use short feedback paths and avoid routing inputs beside the output pins of the second amplifier. The verified 10 MHz gain-bandwidth product and 9 V/µs slew rate provide adequate margin for audio-band signals, but practical distortion also depends on output amplitude, load, feedback resistor values, and loop stability. Verify the final filter response and noise with the selected external components, especially when replacing NE5532ADR with a higher-performance device.
