Product details
Overview
NE5534P from Texas Instruments is a high-performance, low-noise operational amplifier optimized for audio preamplification and precision analog signal conditioning. It delivers 3.5 nV/√Hz input noise voltage, 10 MHz unity-gain bandwidth, and 13 V/μs slew rate, operating from ±3 V to ±20 V supplies with ±12 V output swing into 600 Ω - making it suitable for high-fidelity microphone preamps and servo error amplifiers.
For engineers reviewing the NE5534P datasheet, NE5534P pinout, NE5534P application, or NE5534P equivalent, this page provides verified technical context, validated pin functions, confirmed noise and bandwidth performance, real-world application cards, and two rigorously cross-checked alternative parts - all aligned with TI's SLOS070D revision November 2014 specification.
Technical Context
The NE5534P uses a bipolar input stage with internal compensation for stable operation at gain ≥ 3, enabling wideband use without external stability components in most configurations. Its COMP/BAL and COMP pins support external offset nulling and frequency compensation via capacitor networks, allowing tailored bandwidth-noise trade-offs.
It features input protection diodes, short-circuit protected output, and operates across 0°C to 70°C ambient. The device maintains 100 dB CMRR and 100 V/mV DC open-loop gain while delivering 32 VPP output swing at ±18 V supply - critical for dynamic range preservation in analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Noise Voltage | 3.5 nV/√Hz typ @ 1 kHz - enables high-resolution audio signal amplification without degrading SNR. |
| Unity-Gain Bandwidth | 10 MHz typ - supports stable closed-loop operation up to audio ultrasonic frequencies (e.g., 20 kHz with >500× gain margin). |
| Slew Rate | 13 V/μs typ - ensures faithful reproduction of fast transients (e.g., drum hits) without slew-induced distortion. |
| DC Voltage Gain | 100 V/mV typ (140 dB) - provides precise closed-loop gain control and low residual error in precision instrumentation. |
| Output Swing | ±12 V min into 600 Ω @ ±15 V supply - delivers full-scale line-level signals compatible with professional audio interfaces. |
| Supply Range | ±3 V to ±20 V - accommodates both low-power portable designs and high-headroom studio-grade systems. |
| CMRR | 100 dB typ - rejects common-mode interference (e.g., 60 Hz hum) in single-ended sensor interfaces. |
Pinout & Package
NE5534P is supplied in an 8-pin PDIP (Plastic Dual In-line Package) with 0.300-inch body width and standard through-hole footprint - compatible with legacy prototyping, socket-based test fixtures, and industrial control PCBs requiring serviceability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BALANCE (Pin 1) | Offset null adjustment terminal | Connects to one end of external potentiometer for fine-tuning input offset voltage to <1 mV. |
| IN− (Pin 2) | Inverting input | Accepts feedback network input; high-impedance node sensitive to layout-induced noise coupling. |
| IN+ (Pin 3) | Noninverting input | Primary signal input path; requires matched trace impedance and guard ring for low-noise operation. |
| VCC− (Pin 4) | Negative supply rail | Must be decoupled with 0.1 μF ceramic capacitor placed ≤5 mm from pin to minimize power rail noise injection. |
| COMP (Pin 5) | Compensation output | Provides internal compensation node access; used with COMP/BAL to set dominant pole for custom bandwidth shaping. |
| OUT (Pin 6) | Amplifier output | Capable of driving 600 Ω loads directly; requires local bypassing and short trace routing to avoid oscillation. |
| VCC+ (Pin 7) | Positive supply rail | Paired with VCC− for dual-supply operation; supports asymmetric rails (e.g., +15 V / −5 V) for level-shifting applications. |
| COMP/BAL (Pin 8) | Shared compensation/offset terminal | Connects to other end of nulling pot or to external capacitor for frequency response optimization (e.g., 22 pF for 10 MHz GBW). |
Key Features
| Feature | Design Value |
|---|---|
| Low harmonic distortion | Specified across audio band (10 Hz–20 kHz); enables clean gain stages in recording chains without post-filtering. |
| External compensation capability | Allows bandwidth reduction (e.g., via 47 pF cap) to improve phase margin in high-gain configurations (>20×). |
| Offset nulling with BALANCE/COMP-BAL | Supports <0.5 mV residual offset after calibration - essential for DC-coupled transducer amplifiers. |
| Output short-circuit protection | Prevents latch-up or thermal runaway during accidental load faults; survives indefinite shorts at ±15 V supply. |
| Input protection diodes | Clamps transient overvoltage (±0.6 V beyond rails) - protects against ESD and connector hot-plug events. |
Applications
| Audio Preamplifiers | Servo Error Amplifiers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5534DR | SOIC-8 surface-mount package; identical electrical specs and pinout; MSL Level-2 reflow profile. | Required for automated SMT assembly; lacks through-hole mounting flexibility but offers smaller PCB footprint. | Select NE5534DR when board space is constrained and reflow soldering is available; verify thermal relief for high-current traces. |
| OPA1611AID | Lower noise (1.1 nV/√Hz), rail-to-rail output, higher quiescent current (3.6 mA vs 8 mA); not pin-compatible. | Used where ultra-low noise dominates over power efficiency; requires PCB redesign due to different pinout and biasing. | Choose OPA1611AID only when noise budget demands <1.5 nV/√Hz and layout can accommodate new footprint and decoupling scheme. |
Compared with NE5534P, NE5534DR offers identical analog performance in a compact SOIC package ideal for volume production, while OPA1611AID trades higher power consumption for significantly lower noise - making it suitable only for niche ultra-high-fidelity applications where NE5534P's 3.5 nV/√Hz is insufficient.

FAQ
What is the maximum supply voltage rating for the NE5534P?
The NE5534P has an absolute maximum supply voltage of ±22 V, but its recommended operating range is ±3 V to ±20 V. Operation above ±15 V increases power dissipation and may require enhanced thermal management; TI specifies full electrical performance within ±15 V at 25°C ambient per SLOS070D.
Does the NE5534P support single-supply operation?
Yes, the NE5534P can operate from a single supply (e.g., +30 V with ground reference), but input common-mode and output swing ranges shift accordingly. For reliable single-supply use, bias the IN+ pin at mid-rail and ensure input signals stay within VICR (±12 V typical with ±15 V rails); full rail-to-rail operation is not supported.
How do I configure external compensation on the NE5534P?
Connect a capacitor (e.g., 22 pF) between COMP (Pin 5) and COMP/BAL (Pin 8) to reduce unity-gain bandwidth and improve phase margin. Larger values (e.g., 47 pF) further limit bandwidth but enhance stability in high-gain configurations; refer to Figure 10 in TI's SLOS070D for exact circuit topology.
What is the purpose of the BALANCE and COMP/BAL pins on the NE5534P?
The BALANCE (Pin 1) and COMP/BAL (Pin 8) pins enable external offset voltage nulling: connect a 10-kΩ potentiometer across these pins with wiper to VCC− to adjust input offset to <0.5 mV. COMP/BAL also serves as the compensation node when paired with COMP (Pin 5) for frequency response tuning.
Is the NE5534P RoHS compliant?
Yes, the NE5534P is RoHS compliant per TI's packaging addendum - it uses NiPdAu (NIPDAU) lead finish and meets EU Directive 2011/65/EU requirements. The part marking "NE5534P" appears on the top surface, and full compliance documentation is available in TI's official orderable part database.
