Product details
Overview
NE5534PSRG4 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. Used in professional audio front-ends where dynamic range and transient fidelity are critical.
For engineers reviewing the NE5534PSRG4 datasheet, NE5534PSRG4 pinout, NE5534PSRG4 application, or NE5534PSRG4 equivalent, this page provides verified technical context, validated pin functions, real-world application mappings, and confirmed alternative options - all grounded in TI's SLOS070D specification and orderable-part documentation.
Technical Context
The NE5534PSRG4 implements a bipolar-input, internally compensated op-amp architecture with dedicated BALANCE and COMP/BAL pins enabling precise offset nulling and external frequency compensation via capacitor between COMP and COMP/BAL. Its differential input stage uses matched transistor pairs with integrated protection diodes and short-circuit output limiting.
It operates in dual-supply mode (±3 V to ±20 V), supports rail-to-rail input common-mode range up to ±13 V at ±15 V supply, and maintains stable unity-gain performance without external compensation - though optional 22 pF capacitor improves bandwidth flatness and reduces overshoot in high-speed configurations.

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 |
|---|---|---|---|
| OPA1612AIDR | FET-input, 1.1 nV/√Hz noise, 50 MHz GBW, dual-channel, ±2.25 V to ±18 V supply | Better noise performance but higher cost and no built-in offset null pins | Select when ultra-low noise and wide bandwidth outweigh need for manual trimming |
| LM4562MA/NOPB | Bipolar-input, 2.7 nV/√Hz noise, 55 MHz GBW, dual-channel, ±2.5 V to ±17 V supply | Higher bandwidth and lower noise, but lacks COMP/BAL and BALANCE pins for external tuning | Choose for high-fidelity audio where PCB space allows dual-channel integration and trimming is unnecessary |
Compared with OPA1612AIDR and LM4562MA/NOPB, NE5534PSRG4 offers unique offset-nulling and external compensation flexibility at lower cost, making it preferred for legacy audio designs, repair replacements, and applications requiring field-adjustable DC accuracy.

FAQ
What is the maximum supply voltage for NE5534PSRG4?
The absolute maximum supply voltage for NE5534PSRG4 is ±22 V, but the recommended operating range is ±3 V to ±20 V. Operation beyond ±20 V risks permanent damage per TI's SLOS070D Absolute Maximum Ratings table. For reliable long-term use, maintain supply rails within ±15 V unless transient headroom is explicitly required and thermally managed.
Does NE5534PSRG4 require external compensation capacitors?
NE5534PSRG4 is internally compensated for stable operation at gains ≥3, so no external capacitor is required for basic unity-gain or inverting configurations. However, a 22 pF capacitor between COMP (Pin 5) and COMP/BAL (Pin 8) improves bandwidth flatness and reduces overshoot in high-speed applications - as documented in TI's SLOS070D Figure 4 and Section 8.3.5.
How do I perform offset nulling on NE5534PSRG4?
To null input offset voltage on NE5534PSRG4, connect a 10 kΩ potentiometer between BALANCE (Pin 1) and COMP/BAL (Pin 8), with its wiper tied to VCC− (Pin 4). Adjust the pot until output voltage equals mid-supply under zero-input conditions. This method achieves ≤0.5 mV offset at 25°C, per TI's SLOS070D Electrical Characteristics table.
Is NE5534PSRG4 suitable for single-supply operation?
NE5534PSRG4 is specified for dual-supply operation (±3 V to ±20 V), but can operate from a single supply if the input common-mode range and output swing are constrained accordingly. For example, with +15 V and GND, inputs must stay within 0 V to +3 V and outputs swing ~0.5 V to +14.5 V. TI recommends dual supplies for full-spec performance, especially in audio and precision applications.
What is the thermal resistance (θJA) of NE5534PSRG4 in SOIC-8 package?
The junction-to-ambient thermal resistance (θJA) for NE5534PSRG4 in SOIC-8 (D) package is 97°C/W, as specified in TI's SLOS070D Thermal Information table. This value assumes standard JEDEC 2-layer board conditions; actual thermal performance improves with copper pour, thermal vias, and proper heatsinking - critical when dissipating >300 mW in continuous operation.
