Product details
Overview
NE5534ADRE4 from Texas Instruments is a precision, low-noise operational amplifier optimized for high-fidelity audio and instrumentation applications. It delivers 3.5 nV/√Hz input noise voltage, 10 MHz unity-gain bandwidth, and 13 V/μs slew rate with ±3 V to ±20 V dual-supply operation and ±12 V output swing into 600 Ω at ±15 V supplies.
For engineers reviewing the NE5534ADRE4 datasheet, NE5534ADRE4 pinout, NE5534ADRE4 application, or NE5534ADRE4 equivalent, this device is selected for demanding analog signal conditioning where low distortion, wide bandwidth, and offset nulling capability are critical - especially in preamplifier stages, servo loops, and medical sensor front-ends.
Technical Context
The NE5534ADRE4 features internally compensated stability for closed-loop gain ≥3, with external compensation support via COMP and COMP/BAL pins to tailor frequency response. Its bipolar input stage provides high input resistance (≥30 kΩ), low input bias current (≤300 nA typ), and robust common-mode rejection (100 dB typ) over ±12 V input range.
It integrates input protection diodes, output short-circuit protection, and dedicated offset-null circuitry using BALANCE and COMP/BAL pins. The SOIC-8 package supports surface-mount assembly while maintaining thermal resistance of 97 °C/W (RθJA) under standard PCB conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Noise Voltage | 3.5 nV/√Hz typ at 1 kHz - enables high-resolution audio and low-level sensor amplification without added noise floor. |
| Unity-Gain Bandwidth | 10 MHz typ - supports stable gain-of-1 buffering up to audio and ultrasonic frequencies with minimal phase shift. |
| Slew Rate | 13 V/μs typ - ensures faithful reproduction of fast transients in audio and pulse-amplification circuits. |
| Common-Mode Rejection | 100 dB typ - rejects power supply ripple and EMI coupling in single-ended sensor interfaces. |
| Output Swing | ±12 V min into 600 Ω at ±15 V supply - delivers full-rail dynamic range for line-driving and active filter applications. |
| Supply Voltage Range | ±3 V to ±20 V - accommodates both low-power portable designs and high-headroom studio-grade systems. |
| DC Voltage Gain | 100 V/mV typ (140 dB) - provides precise closed-loop accuracy in precision instrumentation and feedback control. |
Pinout & Package
NE5534ADRE4 is housed in an 8-pin SOIC (D) package measuring 4.90 mm × 3.91 mm, with standard JEDEC MS-012AC footprint and moisture sensitivity level (MSL) 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. |
| IN− (Pin 2) | Inverting input | Primary negative feedback node; accepts differential or single-ended signals with ±12 V common-mode range. |
| IN+ (Pin 3) | Noninverting input | High-impedance signal input; used in noninverting configurations and reference-sensing applications. |
| VCC− (Pin 4) | Negative supply rail | Accepts −3 V to −20 V; must be bypassed with 0.1 μF ceramic capacitor near pin for noise immunity. |
| COMP (Pin 5) | Compensation output | Provides internal compensation node for external capacitor connection to adjust bandwidth/stability. |
| OUT (Pin 6) | Amplified output | Capable of ±12 V swing into 600 Ω; includes short-circuit protection and low output impedance (0.3 Ω). |
| VCC+ (Pin 7) | Positive supply rail | Accepts +3 V to +20 V; requires local 0.1 μF ceramic bypass to ground for stable high-frequency operation. |
| COMP/BAL (Pin 8) | Shared compensation/offset node | Connects to other end of nulling pot or to COMP via capacitor for frequency shaping and offset tuning. |
Key Features
| Feature | Design Value |
|---|---|
| Low harmonic distortion | Typical THD <0.002% at 1 kHz - preserves signal integrity in high-fidelity audio paths and measurement chains. |
| External compensation | COMP and COMP/BAL pins allow configurable gain-bandwidth trade-offs without redesigning feedback networks. |
| Offset nulling capability | Dedicated BALANCE and COMP/BAL pins enable sub-mV DC error correction in precision DC-coupled systems. |
| Output short-circuit protection | Internally limits current to ~38 mA - prevents latch-up or damage during fault conditions in driving applications. |
| Wide supply range | Operates from ±3 V (low-power battery systems) to ±20 V (high-dynamic-range studio gear) without re-biasing. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2134PA | CMOS input (fA bias), lower noise current (0.2 pA/√Hz), but higher voltage noise (8 nV/√Hz); no external compensation pins. | Better for ultra-high-Z sensor interfaces; unsuitable where COMP/BAL-based stability tuning or bipolar input linearity is required. | Select OPA2134PA only when input bias current is dominant concern and external compensation is unnecessary. |
| LM4562MA | Lower voltage noise (2.7 nV/√Hz), higher slew rate (20 V/μs), but fixed internal compensation and no offset-null pins. | Superior for wideband audio line drivers; lacks BALANCE/COMP/BAL flexibility for precision DC-coupled servo or instrumentation use. | Choose LM4562MA for pure AC-coupled, high-speed audio paths; retain NE5534ADRE4 when offset trimming or custom compensation is needed. |
Compared with OPA2134PA and LM4562MA, NE5534ADRE4 uniquely combines bipolar-input linearity, user-adjustable offset nulling, and external frequency compensation - making it irreplaceable in applications requiring both precision DC performance and tunable AC response.

FAQ
What is the operating temperature range for the NE5534ADRE4?
The NE5534ADRE4 is rated for operation from 0°C to +70°C ambient temperature. This commercial-grade specification aligns with its NE5534x family designation and distinguishes it from the extended-temperature SA5534x variants rated for –40°C to +85°C. Thermal derating applies above 70°C per the datasheet's RθJA = 97 °C/W rating.
Does the NE5534ADRE4 require external compensation capacitors?
The NE5534ADRE4 is internally compensated for stable operation at closed-loop gains ≥3, so no external capacitor is required for basic unity-gain-stable use. However, an external capacitor between COMP and COMP/BAL pins is supported to optimize bandwidth, phase margin, or slew-induced distortion in specific applications - as documented in Figure 10 of the SLOS070D datasheet.
How is offset voltage adjusted on the NE5534ADRE4?
Offset voltage on the NE5534ADRE4 is adjusted using a 10-kΩ potentiometer connected between BALANCE (Pin 1) and COMP/BAL (Pin 8), with the wiper grounded. This configuration allows fine-tuning of input offset to <1 mV in precision DC-coupled circuits - a capability confirmed in Section 8.3.1 and Figure 10 of the official TI datasheet.
Can the NE5534ADRE4 operate from a single supply?
Yes, the NE5534ADRE4 can operate from a single supply, provided the input common-mode and output swing ranges remain within specifications. With VCC+ = +15 V and VCC− = 0 V, the input common-mode range extends to ±12 V referenced to midpoint, and output swing reaches ~0.5 V to ~14.5 V into high-Z loads. Proper biasing and decoupling are essential, as detailed in Section 8.4 and Layout Guidelines.
What is the maximum output current capability of the NE5534ADRE4?
The NE5534ADRE4 provides a typical short-circuit output current of 38 mA, with built-in thermal and current limiting to protect against sustained overload. Under normal linear operation into 600 Ω, it delivers ±12 V peak-to-peak swing - corresponding to ±20 mA continuous output current - verified in Section 7.5 Electrical Characteristics of the SLOS070D datasheet.
