Product details
Overview
NE5534AD 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 - enabling high-fidelity gain stages in studio-grade audio equipment and medical sensor front-ends.
For engineers reviewing the NE5534AD datasheet, NE5534AD pinout, NE5534AD application, or NE5534AD equivalent, key selection criteria include its balanced offset-nulling capability (BALANCE and COMP/BAL pins), external compensation flexibility (COMP pin), 8-pin SOIC package compatibility, and guaranteed 0°C to 70°C operating range per TI's production data.
Technical Context
The NE5534AD is internally compensated for stable operation at closed-loop gains ≥3, but supports external frequency compensation via the COMP and COMP/BAL pins to optimize bandwidth and phase margin for specific load conditions. Its bipolar input stage provides low input bias current (20–300 nA typ) and high DC voltage gain (100 V/mV typ), while the output stage delivers ±14 V swing into 600 Ω with 38 mA short-circuit current capability.
It features input protection diodes, output short-circuit protection, and dedicated terminals for offset voltage nulling - enabling precision calibration in servo error amplifiers and telephone channel amplifiers. The device operates across ±3 V to ±20 V supplies and maintains 100 dB CMRR and 80–100 dB PSRR over its full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Noise Voltage | 3.5 nV/√Hz typ @ 1 kHz - enables high-resolution audio signal amplification without audible hiss. |
| Unity-Gain Bandwidth | 10 MHz typ - supports wideband applications including active filters and video signal conditioning. |
| Slew Rate | 13 V/μs typ - preserves transient fidelity in fast-rising audio transients and pulse amplification. |
| DC Voltage Gain | 100 V/mV typ (140 dB) - ensures precise closed-loop gain accuracy in instrumentation and servo loops. |
| CMRR | 100 dB typ - rejects common-mode interference in noisy industrial or medical environments. |
| Supply Range | ±3 V to ±20 V - accommodates both low-voltage portable designs and high-dynamic-range line-powered systems. |
| Output Swing | 32 VPP typ @ ±18 V, RL ≥ 600 Ω - delivers full-rail headroom for professional audio line drivers. |
Pinout & Package
NE5534AD 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 (Level-2-260°C-1 year MSL rating).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BALANCE (Pin 1) | Offset null adjustment | Connects to center tap of 10 kΩ potentiometer for manual input offset cancellation. |
| IN− (Pin 2) | Inverting input | Differential input node accepting feedback signals in inverting amplifier configurations. |
| IN+ (Pin 3) | Noninverting input | High-impedance input for reference or signal source in noninverting buffer/gain stages. |
| VCC− (Pin 4) | Negative supply rail | Accepts −3 V to −20 V; must be bypassed with 0.1 μF ceramic capacitor near pin. |
| COMP (Pin 5) | External compensation | Connects to COMP/BAL to add frequency-compensation capacitor for stability tuning. |
| OUT (Pin 6) | Amplifier output | Capable of ±14 V swing into 600 Ω; includes short-circuit protection and thermal shutdown. |
| VCC+ (Pin 7) | Positive supply rail | Accepts +3 V to +20 V; requires local 0.1 μF ceramic bypass to ground. |
| COMP/BAL (Pin 8) | Shared compensation/offset node | Configurable as second offset null terminal or compensation capacitor return point. |
Key Features
| Feature | Design Value |
|---|---|
| Low harmonic distortion | Specified in TI SLOS070D - enables clean signal reproduction in audio preamps and measurement systems. |
| External compensation capability | COMP and COMP/BAL pins allow bandwidth/phase-margin optimization for capacitive loads or custom gain profiles. |
| Offset nulling with dual terminals | BALANCE and COMP/BAL support precision trimming using a single potentiometer - critical for DC-coupled servo loops. |
| Output short-circuit protection | Guaranteed safe operation under continuous output-to-rail shorts - reduces system-level fault handling complexity. |
| Wide supply voltage range | ±3 V to ±20 V operation supports both battery-powered portables and high-headroom line-powered gear. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5534ADR | Same electrical specs and SOIC-8 package; differs only in tape-and-reel packaging (2500 pcs) and RoHS compliance. | No functional difference - identical use in audio, medical, and telecom designs. | Select NE5534ADR for volume production with automated pick-and-place; NE5534AD is obsolete per TI's packaging addendum. |
| SA5534ADR | Extended temperature range (−40°C to +85°C); otherwise identical noise, slew rate, and gain specs. | Required for automotive or outdoor industrial deployments where ambient exceeds 70°C. | Choose SA5534ADR when operating outside 0°C–70°C; not drop-in due to different temp grade qualification. |
Compared with NE5534AD, NE5534ADR offers identical performance in a RoHS-compliant, production-ready tape-and-reel format, while SA5534ADR extends operational reliability to harsher environments - making the latter essential for extended-temperature applications despite shared pinout and circuit design.

FAQ
What is the maximum supply voltage for NE5534AD?
The absolute maximum supply voltage for NE5534AD is ±22 V, but TI specifies recommended operation from ±3 V to ±20 V. Exceeding ±22 V risks permanent damage per Absolute Maximum Ratings in SLOS070D. For reliable long-term use, maintain supply within ±15 V unless transient testing confirms margin at ±18 V.
Does NE5534AD support single-supply operation?
NE5534AD is designed for dual-supply operation (±VCC), but can be used in single-supply configurations with appropriate level-shifting and biasing - e.g., by referencing IN+ to VCC/2 and ensuring input/output stay within VICR (±12 V typical) and VO(PP) limits. TI's datasheet does not guarantee rail-to-rail performance in single-supply mode.
How do I configure the BALANCE and COMP/BAL pins on NE5534AD?
For offset nulling, connect a 10 kΩ potentiometer between BALANCE (Pin 1) and COMP/BAL (Pin 8), with wiper to VCC−. For external compensation, connect a capacitor (e.g., 22 pF) between COMP (Pin 5) and COMP/BAL (Pin 8). Do not use both functions simultaneously - refer to Figure 10 in SLOS070D for validated schematics.
Is NE5534AD pin-compatible with NE5534ADR?
Yes - NE5534AD and NE5534ADR share identical SOIC-8 pinout, electrical characteristics, and thermal specifications. The only differences are packaging (tube vs. tape-and-reel) and RoHS compliance status. NE5534ADR is the active, recommended replacement per TI's packaging addendum.
What is the typical input bias current of NE5534AD at 25°C?
The typical input bias current of NE5534AD is 20 nA at 25°C (with a max of 300 nA), measured under VO = 0 V conditions. This value increases with temperature - up to 2000 nA over full range - so designs requiring ultra-low bias should verify worst-case leakage in high-impedance sensor interfaces.
