Product details
Overview
NE5534DRE4 from Texas Instruments is a precision, low-noise operational amplifier optimized for audio preamplification and high-fidelity signal conditioning. 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 - enabling clean amplification of weak analog signals in professional audio front-ends.
For engineers reviewing the NE5534DRE4 datasheet, NE5534DRE4 pinout, NE5534DRE4 application, or NE5534DRE4 equivalent, this device is selected for demanding analog signal chains where low distortion, wide output swing (32 VPP at ±18 V), and offset nulling capability are critical - especially in microphone preamps, servo error amplifiers, and medical instrumentation.
Technical Context
The NE5534DRE4 uses a compensated bipolar input stage with internal gain ≥3, supporting stable unity-gain operation only when external compensation is applied between COMP and COMP/BAL pins. Its differential pair architecture enables high CMRR (100 dB) and PSRR (100 dB), while input protection diodes and short-circuit protected output ensure robustness in real-world circuits.
Offset voltage nulling is implemented via BALANCE and COMP/BAL pins using an external potentiometer, allowing precise trimming of VIO (typ. 0.5–4 mV). The SOIC-8 package supports surface-mount integration with thermal resistance θJA = 97°C/W, and operation across 0°C to 70°C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Noise Voltage | 3.5 nV/√Hz typ - enables high-resolution amplification of microvolt-level audio or sensor signals without adding measurable noise floor. |
| Unity-Gain Bandwidth | 10 MHz typ - supports full-spectrum audio (20 Hz–20 kHz) with ample phase margin and minimal group delay distortion. |
| Slew Rate | 13 V/μs typ - prevents slew-induced distortion on fast transients (e.g., drum hits, square-wave edges) in audio paths. |
| Output Swing (±18 V) | 32 VPP min - delivers rail-to-rail usable dynamic range into 600 Ω loads, essential for line-driving and active filter stages. |
| CMRR / PSRR | 100 dB typ each - rejects power supply ripple and common-mode interference in noisy industrial or mixed-signal environments. |
| Supply Range | ±3 V to ±20 V - accommodates both low-voltage portable designs and high-headroom studio-grade systems. |
| Input Offset Voltage | 0.5–4 mV (25°C) - minimized via external nulling circuitry for DC-coupled precision applications like servo loops. |
Pinout & Package
NE5534DRE4 is housed in an 8-pin SOIC (D) package measuring 4.90 mm × 3.91 mm, with standard JEDEC MS-012AC footprint and RoHS-compliant NiPdAu lead finish. Thermal resistance θJA = 97°C/W supports continuous operation up to 70°C ambient without forced cooling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BALANCE (Pin 1) | Offset null adjustment input | Connects to one end of external potentiometer for fine-tuning input offset voltage to <1 mV. |
| IN− (Pin 2) | Inverting input | Primary feedback node in inverting configurations; accepts differential input with VICR = ±12 V at ±15 V supply. |
| IN+ (Pin 3) | Noninverting input | High-impedance (30–100 kΩ) input for unity-gain buffers or noninverting gain stages. |
| VCC− (Pin 4) | Negative supply rail | Accepts −3 V to −20 V; must be decoupled with 0.1 μF ceramic capacitor placed within 2 mm of pin. |
| COMP (Pin 5) | Compensation output | Provides internal compensation node; tied to COMP/BAL for external capacitor-based frequency shaping. |
| OUT (Pin 6) | Amplifier output | Capable of ±16 V swing into 600 Ω; short-circuit protected with 38 mA current limit. |
| VCC+ (Pin 7) | Positive supply rail | Accepts +3 V to +20 V; requires local 0.1 μF bypass to ground for noise immunity. |
| COMP/BAL (Pin 8) | Combined compensation & null input | Shared terminal for external capacitor (22–47 pF) to adjust bandwidth or potentiometer wiper for offset trim. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise bipolar input stage | 3.5 nV/√Hz input voltage noise at 1 kHz - preserves SNR in mic preamp and EEG front-end designs. |
| External frequency compensation | COMP and COMP/BAL pins enable bandwidth tailoring (e.g., 22 pF → 10 MHz GBW; 47 pF → 50 kHz dominant pole). |
| Offset voltage nulling | BALANCE and COMP/BAL support 2-terminal potentiometer connection for <1 mV residual VIO. |
| High-output drive capability | Delivers ±16 V into 600 Ω with <0.002% THD+N - suitable for driving long cables or reactive loads without buffering. |
| Dual-supply flexibility | Operates from ±3 V (low-power portable) to ±20 V (high-dynamic-range studio gear) with no performance degradation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2134PA | FET-input (10 fA IIB), lower noise current (0.2 pA/√Hz), but higher voltage noise (8 nV/√Hz); no offset null pins. | Better for high-Z sensor interfaces (piezo, pH probe); unsuitable where VIO trimming is required. | Select OPA2134PA only when ultra-low input bias current outweighs need for offset adjustment and lowest voltage noise. |
| LM4562MA | Lower noise (2.7 nV/√Hz), higher slew rate (20 V/μs), but fixed internal compensation; no COMP/BAL or BALANCE pins. | Superior for fixed-gain, wideband audio paths; lacks external bandwidth tuning or DC offset correction capability. | Choose LM4562MA for highest fidelity in non-adjustable, high-speed applications; retain NE5534DRE4 when design requires flexibility in compensation or nulling. |
Compared with OPA2134PA and LM4562MA, the NE5534DRE4 uniquely combines low voltage noise, external compensation, and offset nulling in a single SOIC-8 package - making it irreplaceable in tunable, precision analog systems where DC accuracy and bandwidth control are co-required.

FAQ
What is the maximum supply voltage rating for NE5534DRE4?
The absolute maximum supply voltage for NE5534DRE4 is ±22 V, but recommended operating range is ±3 V to ±20 V. Exceeding ±22 V risks permanent damage per TI's Absolute Maximum Ratings table. For reliable long-term operation at ±18 V, ensure thermal dissipation stays within limits using the 97°C/W θJA value and appropriate PCB copper area. NE5534DRE4 must never operate beyond these boundaries.
Does NE5534DRE4 require external compensation capacitors?
Yes - NE5534DRE4 is internally compensated for closed-loop gains ≥3, but unity-gain stability requires external compensation between COMP (Pin 5) and COMP/BAL (Pin 8). A 22 pF capacitor yields ~10 MHz bandwidth; larger values reduce bandwidth and improve phase margin. Without this capacitor, NE5534DRE4 may oscillate in unity-gain or low-gain configurations.
How is offset voltage adjusted on NE5534DRE4?
Offset voltage on NE5534DRE4 is trimmed using a 10 kΩ potentiometer connected between BALANCE (Pin 1) and COMP/BAL (Pin 8), with wiper grounded. Adjusting the potentiometer changes the current injected into the input stage, canceling VIO. This allows reduction of typical 0.5–4 mV offset to <1 mV - critical for DC-coupled applications like servo amplifiers where NE5534DRE4 is deployed.
What is the output drive capability of NE5534DRE4 into 600 Ω?
At ±18 V supply, NE5534DRE4 delivers a minimum 32 VPP output swing into 600 Ω, corresponding to ±16 V amplitude. This meets professional audio line-driving standards and supports full-scale signal transmission without clipping. Output short-circuit current is limited to 38 mA, protecting NE5534DRE4 during fault conditions while maintaining integrity under sustained load.
Is NE5534DRE4 suitable for single-supply operation?
NE5534DRE4 can operate from a single supply (e.g., +12 V with GND), but its input common-mode range extends only to within ~3 V of the negative rail - so with GND as VCC−, inputs must stay ≥3 V above GND. For true rail-to-rail input operation, level-shifting or dual-supply configuration is required. NE5534DRE4's design prioritizes dual-supply performance, and most published application circuits assume ±15 V or ±18 V.
