Product details
Overview
NE5534PSRE4 from Texas Instruments is a low-noise, high-slew-rate operational amplifier optimized for audio preamplification and precision analog signal conditioning. It delivers 3.5 nV/√Hz input noise voltage, 13 V/μs slew rate, and 10 MHz unity-gain bandwidth with ±3 V to ±20 V dual-supply operation and internal compensation for gain ≥3. It is used in professional audio front-ends where wide dynamic range and low distortion are critical.
For engineers reviewing the NE5534PSRE4 datasheet, NE5534PSRE4 pinout, NE5534PSRE4 application, or NE5534PSRE4 equivalent, this page provides verified technical context, SOIC-8 package mapping, offset-nulling and external compensation capabilities, real-world audio and instrumentation use cases, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The NE5534PSRE4 implements a bipolar-input, internally compensated op-amp architecture with dedicated BALANCE and COMP/BAL pins enabling precise offset nulling and adjustable frequency compensation via external capacitor. Its high open-loop gain (100 V/mV typ) and 100 dB CMRR support stable closed-loop performance in demanding dc-coupled systems.
It features input protection diodes, output short-circuit protection, and operates across ±3 V to ±20 V supplies. The device is specified for 0°C to 70°C ambient temperature and supports both single- and dual-supply configurations - though dual supply is required for full rail-to-rail input common-mode range and optimal noise performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Noise Voltage | 3.5 nV/√Hz typ at 1 kHz - enables high-fidelity audio amplification without audible hiss in microphone and phono preamp stages |
| Unity-Gain Bandwidth | 10 MHz typ - supports stable gain-of-1 buffering of signals up to ~1 MHz with minimal phase shift |
| Slew Rate | 13 V/μs typ - preserves transient integrity in fast-rising audio transients and pulse-amplification circuits |
| Common-Mode Rejection Ratio | 100 dB typ - rejects power-supply ripple and EMI coupling common to both inputs in noisy environments |
| Supply Voltage Range | ±3 V to ±20 V - accommodates legacy ±15 V audio rails and modern low-voltage industrial systems |
| Output Swing (±18 V) | 32 VPP typ into 600 Ω - delivers full-scale line-level output without clipping in professional audio interfaces |
| DC Voltage Gain | 100 V/mV typ - ensures <0.01% gain error in precision DC-coupled servo loops and medical sensor amplifiers |
Pinout & Package
NE5534PSRE4 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package measuring 4.90 mm × 3.91 mm, RoHS-compliant, with gull-wing leads and moisture sensitivity level (MSL) Level-2-260°C-1 year.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BALANCE (Pin 1) | Offset null adjustment terminal | Connects to one end of external potentiometer for manual input offset voltage trimming; essential for precision DC-coupled applications |
| IN− (Pin 2) | Inverting input | Differential input node; accepts feedback network for inverting amplifier configurations and active filters |
| IN+ (Pin 3) | Noninverting input | Differential input node; used in noninverting buffers, instrumentation amps, and sensor interface topologies |
| VCC− (Pin 4) | Negative supply rail | Reference for internal biasing; must be connected to negative supply (e.g., −15 V); not ground unless single-supply configured |
| COMP (Pin 5) | Compensation output | Provides access to internal compensation node; used with COMP/BAL to add external capacitor for bandwidth/gain trade-off |
| OUT (Pin 6) | Amplifier output | Low-impedance voltage source capable of driving 600 Ω loads; requires local bypass capacitors to maintain stability |
| VCC+ (Pin 7) | Positive supply rail | Reference for internal biasing; must be connected to positive supply (e.g., +15 V); decoupling mandatory per layout guidelines |
| COMP/BAL (Pin 8) | Shared compensation/offset node | Connects to other end of offset potentiometer or to external capacitor for frequency compensation; dual-function pin requiring careful routing |
Key Features
| Feature | Design Value |
|---|---|
| Low harmonic distortion | Specified in typical characteristics curves - enables clean amplification in high-fidelity audio paths without post-filtering |
| External compensation capability | COMP and COMP/BAL pins allow user-defined bandwidth vs. phase margin trade-off using discrete capacitor (e.g., 22 pF for 10 MHz GBW) |
| Offset nulling capability | BALANCE and COMP/BAL pins support <1 mV residual offset after trimming - critical for dc-coupled medical instrumentation |
| High output drive | 32 VPP swing into 600 Ω load - meets professional audio line-driving standards without external buffer stage |
| Input protection diodes | Integrated clamping diodes protect IN+ and IN− against overvoltage transients up to ±30 V - improves system robustness in field-deployed gear |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA1611AIDR | Lower noise (1.1 nV/√Hz), JFET input, no offset null pins, fixed internal compensation | Better suited for ultra-low-noise mic preamps but lacks external compensation and offset trim for precision dc systems | Select when lowest possible noise dominates; avoid if offset trimming or custom bandwidth shaping is required |
| LM4562MA/NOPB | Similar noise (2.7 nV/√Hz), higher slew rate (20 V/μs), no COMP/BAL pins, unity-gain stable | Optimized for headphone drivers and DAC output stages; lacks dedicated nulling pins for servo-grade accuracy | Prefer for high-current audio output stages; not recommended for applications needing manual offset calibration |
Compared with NE5534PSRE4, OPA1611AIDR offers superior noise performance but forfeits design flexibility in offset control and bandwidth tuning, while LM4562MA/NOPB delivers higher slew rate and stability at the cost of configurability - making NE5534PSRE4 uniquely balanced for mixed-signal instrumentation requiring both precision and adaptability.

FAQ
What is the maximum supply voltage rating for NE5534PSRE4?
The absolute maximum supply voltage for NE5534PSRE4 is ±22 V - exceeding this risks permanent damage. For reliable operation, TI specifies ±3 V to ±20 V as the recommended range. At ±18 V, the device achieves its full 32 VPP output swing into 600 Ω. Always use 0.1-μF ceramic bypass capacitors at each supply pin to prevent instability under dynamic load conditions.
Does NE5534PSRE4 support single-supply operation?
Yes, NE5534PSRE4 can operate from a single supply (e.g., +30 V and ground), but its input common-mode range and output swing become asymmetric. With single supply, the input must remain ≥1.5 V above ground (VICR min = VCC− + 1.5 V), and output cannot swing fully to ground. Dual supply (±15 V) is strongly recommended to leverage the full ±13 V input range and symmetrical 32 VPP output capability of NE5534PSRE4.
How do I configure external compensation on NE5534PSRE4?
To configure external compensation on NE5534PSRE4, connect a capacitor (e.g., 22 pF) between Pin 5 (COMP) and Pin 8 (COMP/BAL). This reduces unity-gain bandwidth from 10 MHz (no cap) to ~10 MHz (with 22 pF) while improving phase margin - critical for driving capacitive loads or achieving flat frequency response in active filters. Do not leave either pin floating; unused pins must be tied appropriately per TI SLOA045 guidelines.
Can NE5534PSRE4 replace NE5534P in existing designs?
Yes, NE5534PSRE4 is a direct functional replacement for NE5534P in most applications, as both share identical electrical specifications and pinout. However, NE5534PSRE4 uses SOIC-8 packaging (4.90 mm × 3.91 mm) versus PDIP-8 (NE5534P), requiring PCB layout revision. Thermal resistance differs (RθJA = 97°C/W vs. 85°C/W), so verify junction temperature under worst-case load before drop-in substitution.
What is the purpose of the BALANCE and COMP/BAL pins on NE5534PSRE4?
The BALANCE (Pin 1) and COMP/BAL (Pin 8) pins on NE5534PSRE4 serve dual functions: BALANCE connects to one end of a 10-kΩ potentiometer for manual input offset voltage nulling, while COMP/BAL serves as the second terminal for that same potentiometer *or* as the connection point for an external compensation capacitor (with Pin 5). This dual-role design enables simultaneous optimization of dc accuracy and ac stability - a key differentiator of NE5534PSRE4 in precision analog systems.
