NE5534AN - 10MHz Low Noise Audio Op-Amp DIP-8 | onsemi
MPN: NE5534AN ✗ Cuối đờiNE5534AN Tóm tắt
An operational amplifier (op-amp) is a high-gain differential voltage amplifier that, with external feedback networks, forms the basis of nearly all analog signal processing: amplification, filtering, buffering, and summation. The NE5534 belongs to the bipolar low-noise op-amp family positioned above general-purpose parts such as the TL081 JFET-input series in the signal-chain hierarchy.
Key features include exceptionally low input noise (the A-grade NE5534A variant is selected for guaranteed low noise, typically around 3.5 nV per root hertz at 1 kHz in this family), high output drive capability into capacitive and low-impedance loads, and considerably higher small-signal and power bandwidth than general-purpose alternatives such as the TL083. Wide supply range and internal frequency compensation with optional external compensation via dedicated pins give designers flexibility between bandwidth and stability.
Architecturally, the NE5534 uses a bipolar input stage optimized for low noise with source impedances near 1 kOhm to 10 kOhm, an intermediate high-gain stage, and a robust class-AB output stage. Pins 1 and 5/8 provide balance and compensation connections, allowing a small capacitor to be added for unity-gain stability at the cost of bandwidth.
Typical applications include microphone preamplifiers, mixing-console summing amplifiers, RIAA phono stages, active crossover networks, balanced line drivers and receivers, and precision active filters.
Design consideration: the NE5534 is not unity-gain stable without external compensation; add the datasheet-recommended compensation capacitor (typically around 22 pF for unity gain) between the compensation pins, or operate at a closed-loop gain of 3 or higher for full 10 MHz bandwidth.

Ứng dụng tiêu biểu
NE5534AN phù hợp cho 6 Áp dụngs: Microphone Preamplifier, Mixing Console Summing Amplifier, RIAA Phono Preamplifier, Balanced Line Driver and Receiver, Active Crossover and Equalizer Filters, Test and Measurement Signal Conditioning.
Microphone Preamplifier
The NE5534AN fits microphone preamps because its bipolar input stage delivers lowest noise with source impedances of roughly 150 Ohm to 10 kOhm, exactly the range of dynamic mics and transformer secondaries. With 10 MHz GBW, a 40 dB closed-loop gain stage still holds full audio bandwidth with margin, and the 13 V/us slew rate handles full-scale transients without slew-induced distortion. The high output drive lets one stage feed long console wiring directly. Use the compensation pin at gains below 3; at typical mic-pre gains of 20 dB to 60 dB, internal compensation is sufficient. Power from +/-15 V rails with 100 nF local decoupling for best noise floor.

Mixing Console Summing Amplifier
In mixing consoles, the NE5534AN historically served as the summing amplifier and bus driver, as documented in diyAudio mixer design threads. Summing amps see many input resistors feeding a virtual ground, so low input voltage and current noise set the console's noise floor; the NE5534's low-noise bipolar input is optimized for the typical 10 kOhm bus resistor values. Its high small-signal bandwidth (10 MHz GBW) preserves headroom across dozens of summed channels, and its improved output drive pushes the mix bus into faders, meters, and downstream line outputs without buffering. The DIP-8 package also makes channel-card repair and upgrades straightforward with pin-compatible replacements.

RIAA Phono Preamplifier
Phono stages demand the lowest possible input noise because cartridge signals are only a few millivolts; the NE5534AN's selected low-noise die (the A-grade process) is a classic choice for MM cartridge equalization at 1 kOhm-47 kOhm source impedances. The 10 MHz GBW keeps the RIAA feedback network accurate: at 40 dB midband gain, the equalization curve stays within fractions of a dB to 20 kHz. Slew rate of 13 V/us prevents overload-induced slewing on clicks and transients. The external compensation pins let designers trade a little bandwidth for rock-solid stability in the high-gain feedback configuration, and the DIP package suits vintage hi-fi restoration where the NE5534AN is the original part.

Balanced Line Driver and Receiver
Professional audio interconnect uses balanced signaling, and the NE5534AN drives and receives balanced lines effectively. As a receiver, its low noise preserves common-mode-rejection gains at typical 10 kOhm input networks; as a driver, the robust output stage sustains 600 Ohm loads at up to +20 dBm levels with low distortion thanks to high power bandwidth. The diyAudio balanced-input power-amp threads document the NE5534 in exactly this unity-gain receiver role - remember to add the approximately 22 pF compensation capacitor at unity gain. Supply operation at +/-15 V (within the 3 V to 20 V rail rating) maximizes clip headroom for studio and live-sound tie lines.

Active Crossover and Equalizer Filters
Active crossovers and graphic/parametric EQs chain multiple Sallen-Key or multiple-feedback filter stages, and community discussions note the NE5534/5532 family is 'great for analog filters and volume circuits' because its noise is matched to impedances around 10 kOhm - the standard value range for filter networks. The 10 MHz GBW means each filter stage keeps its designed Q and corner frequency accurate at audio frequencies with two to three decades of margin. High output drive lets filter outputs feed level controls and cable capacitance directly. Design filters with resistors of 5 kOhm to 20 kOhm to sit in the noise optimum, and operate stages at gains of 3 or more where possible to avoid compensation capacitors.

Test and Measurement Signal Conditioning
Bench instruments, distortion analyzers, and audio test sets use the NE5534AN as a low-noise input amplifier and precision gain block. The bipolar low-noise input minimizes the amplifier's contribution to measured noise floors, the 13 V/us slew rate keeps wideband transients honest up to several hundred kilohertz at meaningful amplitudes, and the class-AB output drives filters, attenuators, and cable loads without degradation. Supply range up to +/-20 V allows input common-mode ranges and output swings beyond standard +/-15 V systems for extended dynamic range. In service and restoration of legacy test gear, the DIP-8 footprint accepts all pin-compatible 5534 replacements listed on this page, simplifying maintenance of discontinued equipment.

Ghi chú thiết kế
The NE5534AN is NOT unity-gain stable as shipped. In buffer or gain-below-3 configurations, fit the onsemi datasheet-recommended compensation capacitor (approximately 22 pF for unity gain) between pin 5 and pin 8; omitting it produces ringing or sustained oscillation. Note also that JFET op-amps such as the OPA134 are NOT pin-compatible with the 5534 pinout (pin 5 function differs), a fact confirmed on TI's E2E forum - always verify the compensation-pin mapping before substituting other op-amp families.
Decouple pins 4 and 7 with 100 nF ceramic capacitors placed within a few millimeters of the DIP pins, plus 10 uF bulk capacitance per rail on the board. The 10 MHz bandwidth will happily amplify supply-lead inductance into oscillation. Because this is a through-hole part often used on protoboard, keep supply jumpers short and add extra decoupling if rails are shared with high-current output stages. Operation at +/-15 V is typical; the 20 V-per-rail rating leaves headroom for extended-level studio buses.
For minimum noise, keep the summing/input node impedances in the 1 kOhm to 10 kOhm range where the bipolar input stage is optimized; very high source impedances shift the optimum toward JFET-input parts. If offset trim is not required, pins 1 and 5 can be left as per the compensation network per the datasheet application circuits. For unity-gain balanced receivers, a small compensation capacitor plus a low-value feedback resistor (about 15 ohms to isolate load capacitance) yields stable, low-distortion line reception.
Use a ground plane under the amplifier with short feedback paths; keep the feedback resistor traces away from the output trace to avoid parasitic capacitance that erodes phase margin. On legacy single-sided audio boards, add a small ceramic directly at the supply pins even if bulk electrolytics exist nearby. The 7.62 mm DIP row spacing allows machined-pin sockets, strongly recommended for audio applications to enable future op-amp rolling or replacement with the active TI NE5534P.
