Product details
Overview
NE5534DRG4 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 sensor or microphone signals in professional audio equipment.
For engineers reviewing the NE5534DRG4 datasheet, NE5534DRG4 pinout, NE5534DRG4 application, or NE5534DRG4 equivalent, this page provides verified specifications, SOIC-8 package details, offset-nulling and external compensation capabilities, thermal derating guidance, and validated alternatives for audio, medical, and servo amplifier designs.
Technical Context
The NE5534DRG4 features internally compensated gain ≥3 architecture with dedicated COMP and COMP/BAL pins enabling precise external frequency compensation and DC offset nulling. Its bipolar input stage delivers low input bias current (20–300 nA) and high common-mode rejection (100 dB), supporting stable closed-loop operation in high-impedance sensor interfaces.
It operates across 0°C to 70°C ambient temperature with ±15 V typical supply, delivering 32 VPP output swing into 600 Ω and maintaining <0.9 dB average noise figure at 10 Hz–20 kHz - critical for low-distortion analog front-ends in studio-grade audio systems and precision instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Noise Voltage | 3.5 nV/√Hz typ - enables detection of microvolt-level audio or sensor signals without dominant amplifier noise floor |
| Unity-Gain Bandwidth | 10 MHz typ - supports wideband audio amplification up to 20 kHz with ample phase margin |
| Slew Rate | 13 V/μs typ - prevents slew-induced distortion on fast transients like drum hits or pulse edges |
| CMRR | 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 rails and modern low-voltage industrial systems |
| Output Swing | 32 VPP typ at ±18 V / 600 Ω - drives line-level loads directly without output stage buffering |
| DC Voltage Gain | 100 V/mV typ - ensures accurate DC-coupled gain stability in servo error amplifiers |
Pinout & Package
NE5534DRG4 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 enables operation up to 70°C ambient with moderate power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BALANCE (Pin 1) | Offset null adjustment terminal | Connects to potentiometer wiper for manual input offset cancellation - essential for DC-coupled precision applications |
| IN− (Pin 2) | Inverting input | Accepts feedback network input; high-impedance node requiring guarded layout to minimize leakage and noise pickup |
| IN+ (Pin 3) | Noninverting input | High-impedance signal input; sensitive to EMI - must be routed short and away from noisy traces |
| VCC− (Pin 4) | Negative supply rail | Requires local 0.1 μF ceramic bypass capacitor to ground to suppress supply noise coupling into analog path |
| COMP (Pin 5) | Compensation output | Provides internal compensation node for external capacitor connection to tailor bandwidth/stability trade-off |
| OUT (Pin 6) | Amplifier output | Capable of ±16 V swing into 600 Ω; drive strength supports direct connection to ADC drivers or line outputs |
| VCC+ (Pin 7) | Positive supply rail | Paired with Pin 4 for dual-supply operation; bypassing mandatory for THD performance below 0.002% |
| COMP/BAL (Pin 8) | Shared compensation/offset node | Configurable as either external compensation capacitor return or second offset null terminal - enables flexible stability tuning |
Key Features
| Feature | Design Value |
|---|---|
| Low harmonic distortion | 0.9 dB average noise figure (10 Hz–20 kHz) - preserves tonal integrity in audio chain without post-filtering |
| External compensation capability | COMP and COMP/BAL pins allow capacitor-based bandwidth limiting to prevent oscillation in high-gain configurations |
| Offset nulling capability | BALANCE and COMP/BAL pins support <1 mV residual offset after trimming - critical for DC servo loops |
| Output short-circuit protection | Withstands indefinite output-to-rail shorts without latch-up or parametric shift - improves system robustness |
| Input protection diodes | Clamps transient overvoltage on IN+/IN− to ±0.6 V beyond rails - prevents damage from ESD or cable discharge |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 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 for ultra-low-noise mic preamps; unsuitable where manual offset trim or external compensation is required | Select when lowest possible noise dominates; avoid if BALANCE/COMP/BAL functionality is needed |
| LM4562MA/NOPB | Similar noise (2.7 nV/√Hz), dual-channel, no COMP/BAL pins, higher quiescent current (10 mA vs 8 mA) | Preferred for stereo audio paths; lacks single-amplifier flexibility and external compensation control | Choose for dual-channel cost-sensitive designs; not drop-in for NE5534DRG4's single-channel, trimmable layout |
Compared with OPA1611AIDR and LM4562MA/NOPB, NE5534DRG4 uniquely retains user-adjustable offset nulling and external frequency compensation - making it irreplaceable in legacy audio gear service, precision servo calibration, and applications requiring field-trimmable DC accuracy.

FAQ
What is the maximum supply voltage for NE5534DRG4?
The absolute maximum supply voltage for NE5534DRG4 is ±22 V, but recommended operating conditions specify ±3 V to ±20 V. Operation above ±15 V requires careful thermal management due to increased power dissipation - the device's θJA of 97°C/W limits safe continuous use at ±18 V to ≤40°C ambient unless heatsinking is applied. Always observe derating curves in the NE5534DRG4 datasheet.
Does NE5534DRG4 support single-supply operation?
Yes, NE5534DRG4 can operate from a single supply (e.g., +12 V with ground), but its input common-mode range extends only to within ~3 V of the negative rail. For true rail-to-rail input capability, level-shifting or biasing networks are required. The device's output swing remains asymmetric in single-supply mode - verify VICR and VO(PP) specs under your specific VCC and load conditions per the NE5534DRG4 electrical characteristics table.
How do I configure external compensation on NE5534DRG4?
To configure external compensation on NE5534DRG4, connect a capacitor (typically 22 pF to 47 pF) between Pin 5 (COMP) and Pin 8 (COMP/BAL). This reduces unity-gain bandwidth and improves phase margin in high-gain (>10×) configurations. Do not connect the capacitor to ground or supply rails - the COMP/COMP-BAL node forms a controlled pole. Refer to Figure 10 in the NE5534DRG4 datasheet for the exact compensation circuit topology.
What is the purpose of the BALANCE and COMP/BAL pins on NE5534DRG4?
The BALANCE (Pin 1) and COMP/BAL (Pin 8) pins on NE5534DRG4 enable two distinct functions: BALANCE serves as the wiper terminal for a 10-kΩ potentiometer used to null input offset voltage, while COMP/BAL acts as either the return path for external compensation capacitance (when used with Pin 5) or the second terminal for offset nulling (when tied to BALANCE via resistor network). Both functions require external passive components per the NE5534DRG4 application circuit diagram.
Is NE5534DRG4 pin-compatible with NE5534A variants?
Yes, NE5534DRG4 is pin-compatible with NE5534A variants (e.g., NE5534ADR) in the same SOIC-8 package - all share identical pinout, footprint, and electrical interface. However, NE5534A specifies tighter input noise voltage (≤5 nV/√Hz max vs typical 3.5 nV/√Hz for NE5534DRG4), making it preferred for noise-critical designs. No PCB changes are required when substituting within the same package variant.
