Product details
Overview
NE5534ADRG4 from Texas Instruments is a precision low-noise operational amplifier designed for high-fidelity analog signal conditioning in audio and instrumentation systems. 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 - ideal for microphone preamplifiers and servo error amplifiers.
For engineers reviewing the NE5534ADRG4 datasheet, NE5534ADRG4 pinout, NE5534ADRG4 application, or NE5534ADRG4 equivalent, key selection criteria include its SOIC-8 package, internal gain ≥3 compensation, external offset nulling capability via BALANCE/COMP/BAL pins, and verified performance across 0°C to 70°C industrial temperature range.
Technical Context
The NE5534ADRG4 implements a bipolar-input, internally compensated op-amp architecture optimized for unity-gain-stable operation at gains ≥3. Its differential input stage uses matched transistor pairs with on-chip protection diodes, while the output stage provides high current drive (±38 mA short-circuit) and rail-to-rail output swing capability under load.
Frequency response is adjustable via external capacitor between COMP and COMP/BAL pins, enabling trade-offs between bandwidth (10 MHz typ. with 22 pF) and stability. Input bias current (20–300 nA typ.) and CMRR (100 dB typ.) are maintained across ±15 V supply and 25°C ambient, supporting precision DC-coupled applications.
Key Specifications

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 IB), lower noise (8 nV/√Hz), no external compensation pins | Better for ultra-high-Z sensor interfaces; lacks BALANCE/COMP pins for fine-tuning | Select when input bias current <1 pA is critical and offset trimming is handled digitally |
| LM4562MA | Lower noise (2.7 nV/√Hz), higher slew rate (20 V/μs), same SOIC-8 package | Superior for high-end audio DAC output stages requiring minimal distortion | Choose for premium audio where 0.00003% THD+N and rail-to-rail output are mandatory |
Compared with OPA2134PA and LM4562MA, the NE5534ADRG4 offers unique external compensation and offset-nulling flexibility at lower cost, making it optimal for legacy audio designs and industrial servo loops where manual calibration is preferred over digital trimming.

FAQ
What is the maximum supply voltage rating for the NE5534ADRG4?
The NE5534ADRG4 has an absolute maximum supply voltage rating of ±22 V. Operation beyond this limit risks permanent damage. For reliable long-term use, TI specifies recommended operating conditions of ±5 V to ±15 V. The NE5534ADRG4 achieves optimal noise and distortion performance at ±15 V, with full functionality maintained down to ±3 V.
Does the NE5534ADRG4 require external compensation capacitors?
The NE5534ADRG4 is internally compensated for stable operation at gains ≥3, so no external capacitor is required for basic unity-gain or inverting configurations. However, an external capacitor (typically 22 pF) between COMP and COMP/BAL pins allows bandwidth optimization - increasing unity-gain bandwidth to 10 MHz while maintaining phase margin. This flexibility makes the NE5534ADRG4 adaptable to both wideband and precision low-noise applications.
How is offset voltage adjusted on the NE5534ADRG4?
Offset voltage on the NE5534ADRG4 is adjusted using the BALANCE (Pin 1) and COMP/BAL (Pin 8) terminals. A 10 kΩ potentiometer is connected with its ends to VCC+ and VCC−, and its wiper to BALANCE; COMP/BAL is left unconnected during nulling. This configuration injects opposing currents into the input stage to cancel inherent transistor mismatches. The NE5534ADRG4 achieves ≤4 mV input offset after nulling, critical for DC-coupled integrators and precision summing amplifiers.
What is the operating temperature range of the NE5534ADRG4?
The NE5534ADRG4 is rated for operation from 0°C to 70°C ambient temperature - the commercial-grade specification matching the NE5534x family. This range covers standard industrial control panels, consumer audio equipment, and telecom infrastructure operating in climate-controlled environments. For extended temperature applications (−40°C to 85°C), TI offers the SA5534x series, which shares identical electrical characteristics but differs in qualification testing and part marking.
Can the NE5534ADRG4 drive 600 Ω loads effectively?
Yes, the NE5534ADRG4 is explicitly characterized to drive 600 Ω loads, delivering ±12 V peak-to-peak output swing at ±15 V supply and ±32 V at ±18 V. Its output stage provides ±38 mA short-circuit current and maintains low distortion (<0.002% THD+N) under these conditions. This capability meets professional audio line-driving standards and eliminates the need for external buffer transistors in mixer and interface designs.
