NE5532ADRG4 - Dual 10 MHz Low-Noise Op Amp | Texas Instruments
部品番号: NE5532ADRG4 ✓ 生産中NE5532ADRG4 概要
An operational amplifier is an active analog signal-conditioning device that uses high-gain differential feedback to amplify the difference between its two inputs. The dual NE5532 family belongs to the operational-amplifier hierarchy within analog and amplifier ICs. Its two channels can amplify noninverting and inverting signals independently, making it suitable for preamplifiers, active filters, mixers, buffers, and control loops where low noise, moderate bandwidth, and relatively high output-current capability are useful together.
The NE5532ADRG4 combines a 10 MHz typical unity-gain bandwidth with 9 V/µs typical slew rate. Its typical high DC voltage gain is 100 V/mV, while the equivalent input-noise voltage is 5 nV/√Hz at 1 kHz. These characteristics support low-distortion audio signal paths and general feedback-control circuits without requiring a high-speed bipolar or current-feedback amplifier.
Internally, the device uses a bipolar-compatible low-noise amplifier architecture intended for general-purpose precision audio work. Noise performance is especially important when the circuit handles microphone-level, musical-instrument, or balanced-line signals because amplifier noise can establish the input-referred noise floor. The common-mode rejection specification supports rejection of shared interference on differential inputs, while the two-amplifier configuration reduces package count in balanced and stereo circuits.
Typical uses include stereo audio preamplification, active equalizer and crossover stages, microphone and line-level signal conditioning, instrumentation buffers, and low-frequency filter networks. In a preamplifier, both channels can process left and right signals while preserving low-noise performance. In an active filter, the 10 MHz bandwidth provides more open-loop capability than the audio-band signal being shaped, although stability must be verified for the selected noise gain and load.
Designers should keep feedback-loop compensation appropriate for the selected gain, check output swing into the intended load, and provide stable decoupling at the supply pins. Because the available verified data does not state the complete supply-voltage range, input common-mode limits, output-current limits, or thermal resistance, those values must be confirmed in the manufacturer datasheet before final design release.
This product page consolidates verified distributor specifications, pricing context, same-package replacement candidates, and application-oriented engineering guidance. It separates documented facts from unavailable parameters, helping engineers evaluate the NE5532ADRG4 quickly without mistaking an incomplete web summary for a complete electrical characterization.

主な用途
NE5532ADRG4 の用途: 6 件s: Stereo Audio Preamplifier, Active Audio Equalizer, Microphone and Line-Level Conditioning, Instrumentation Signal Buffer, Audio Subwoofer Filter Network, Precision Low-Level Analog Signal Conditioning.
Stereo Audio Preamplifier
The NE5532ADRG4 fits stereo preamplifiers because its two channels provide 10 MHz typical gain-bandwidth product and 9 V/µs typical slew rate in one 8-SOIC package. Its 5 nV/√Hz typical equivalent input-noise density at 1 kHz is particularly useful when amplifying low-level source signals, while 100 dB typical common-mode rejection can reduce common interference on balanced inputs. Each channel can implement a conventional inverting or noninverting gain stage using negative feedback. Designers should verify the required input and output voltage ranges, source-impedance limits, and stability against the load before release.
おすすめ
Active Audio Equalizer
The NE5532ADRG4 is appropriate for active equalizer and tone-control networks that operate well below its 10 MHz typical unity-gain bandwidth. With a 9 V/µs typical slew rate, the amplifier can reproduce moderate-level audio-band waveforms while the 5 nV/√Hz typical input-noise density at 1 kHz limits the amplifier's contribution to the system noise floor. The dual construction supports two linked filter channels. Component tolerances determine the actual boost and cut, while the feedback network must preserve the intended phase margin after adding source resistance, loading, and op-amp noise gain.
おすすめ
Microphone and Line-Level Conditioning
The NE5532ADRG4 can condition microphone or line-level signals where the target signal level is close to the amplifier's noise floor. Its verified 5 nV/√Hz typical equivalent input-noise voltage at 1 kHz makes it preferable to a general-purpose amplifier with materially higher noise, while 100 dB typical common-mode rejection helps when both inputs share interference. Use the two channels for a balanced or stereo conditioning path and apply local input-bias resistors that meet the selected amplifier's bias-current requirements. A clean reference ground and short, shielded input route remain important even when using a low-noise device.
おすすめ
Instrumentation Signal Buffer
The NE5532ADRG4 is suitable for moderate-bandwidth instrumentation buffering when a conventional voltage-feedback operational amplifier is sufficient. Its 100 V/mV typical high DC voltage gain and 100 dB typical common-mode rejection support accurate signal transfer, while the 10 MHz typical unity-gain bandwidth and 9 V/µs typical slew rate provide margin for many low-to-moderate frequency measurement signals. The two channels can buffer differential sensor lines or support gain and filter stages. Final selection requires checking the manufacturer's complete electrical limits, particularly input bias current, output swing, supply range, and capacitive-load behavior.
おすすめ
Audio Subwoofer Filter Network
The NE5532ADRG4 can implement crossover, low-pass, or shelving networks for a subwoofer or small audio system. Its dual amplifier arrangement permits independent filter channels or a cascaded second-order section, while the 10 MHz typical gain-bandwidth product is substantially above audio crossover frequencies. The 9 V/µs typical slew rate helps preserve low distortion on higher-order filters, and the 5 nV/√Hz typical noise density at 1 kHz is useful when the filter follows a quiet source. Choose resistor and capacitor values that keep the closed-loop noise gain compatible with the device's stability characteristics and verify the final response on the target board.
おすすめ
Precision Low-Level Analog Signal Conditioning
The NE5532ADRG4 can serve low-level analog conditioning tasks where 10 MHz bandwidth, 9 V/µs slew rate, and low input noise are more useful than very low power or rail-to-rail operation. The verified 100 dB typical common-mode rejection can suppress shared-mode interference in differential circuits, and the dual package reduces component count when two related channels are required. Because the supplied data does not state the complete input common-mode range, output swing, or input-bias behavior, the manufacturer datasheet must be consulted for the actual operating point. Decoupling, grounding, and feedback compensation remain essential to preserve measured performance.

設計ノート
Place the supply-decoupling capacitor immediately adjacent to the positive and negative supply pins, with a short, low-inductance return path. Although the verified data emphasizes the 10 MHz typical gain-bandwidth product and 9 V/µs typical slew rate, those figures do not remove the need for a quiet supply. Confirm the permitted supply range and decoupling recommendations in the manufacturer datasheet before applying dual or split supplies.
Do not select a replacement solely because it fits an 8-SOIC outline. Check the complete pin functions, input common-mode range, output swing, supply limits, input-bias requirements, noise, bandwidth, and stability for the actual feedback network. The verified cross-reference material supports NE5532AP, NE5532DR, OPA2134, OPA2604, and TLE2072 as candidates, but production substitution still requires datasheet-level signoff and, where appropriate, board-level testing.
Keep audio or instrumentation input traces short, keep the feedback loop compact, and route the return current without sharing narrow paths with output and switching-current loops. Use a solid ground plane and place input-bias resistors close to the noninverting inputs when their thermal noise could influence the result. This layout discipline preserves the benefit of the verified 5 nV/√Hz typical input-noise density and 100 dB typical common-mode rejection.
Verify closed-loop stability at the intended noise gain and with the actual source and load impedances. The 10 MHz typical gain-bandwidth product provides substantial bandwidth margin for audio circuits, but excessive feedback capacitance, long PCB traces, or capacitive loading can still alter phase margin and transient response. Use the manufacturer stability guidance and probe the finished circuit with representative signals before production release.
