Product details
Overview
SA5534P from Texas Instruments is a precision, low-noise bipolar operational amplifier in an 8-pin PDIP package, delivering 3.5 nV/√Hz input noise voltage, 10 MHz unity-gain bandwidth, and 13 V/μs slew rate at ±15 V supply. It features internal compensation for gain ≥3, external offset nulling via BALANCE and COMP/BAL pins, and operates across –40°C to +85°C for industrial-grade audio and instrumentation signal conditioning.
For engineers reviewing the SA5534P datasheet, SA5534P pinout, SA5534P application, or SA5534P equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed industrial applications, and two rigorously cross-checked alternative parts with documented functional and application-level differences.
Technical Context
The SA5534P uses a fully compensated bipolar input stage optimized for high dc accuracy and wide ac bandwidth. Its internal compensation ensures stability at closed-loop gains ≥3, while external capacitor placement between COMP and COMP/BAL enables bandwidth and phase margin tuning for demanding audio and servo loops.
It supports dual-supply operation from ±3 V to ±20 V, delivers ±12 V output swing into 600 Ω, and integrates input protection diodes and output short-circuit protection. The BALANCE and COMP/BAL pins provide dedicated paths for offset nulling and frequency compensation-functions not shared with standard op-amp pinouts.

| Operating Temperature | –40°C to +85°C - certified for deployment in automotive cabin electronics, medical diagnostics, and outdoor telecom equipment |
| Output Swing (±18 V) | 32 VPP typ into 600 Ω - drives professional audio loads directly without output stage buffering |
Pinout & Package
SA5534P is housed in an 8-pin plastic dual in-line package (PDIP) with 0.300-inch body width and through-hole mounting. Pin 1 is marked by a notch or dot; leads are tin-lead (NIPDAU) finish, RoHS-compliant, and rated for manual and wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BALANCE (Pin 1) | Offset null adjustment | Connects to center tap of 10-kΩ potentiometer for precise input offset cancellation in precision DC-coupled circuits |
| IN− (Pin 2) | Inverting input | Primary feedback node in inverting amplifiers; accepts differential input signals with 100 dB CMRR rejection |
| IN+ (Pin 3) | Noninverting input | High-impedance (≥30 kΩ) input for unity-gain buffers and noninverting configurations with minimal loading |
| VCC− (Pin 4) | Negative supply | Reference for internal biasing; must be ≤ –3 V and ≥ –22 V; requires local 0.1-μF ceramic bypass to ground |
| COMP (Pin 5) | Compensation output | Provides access to internal compensation node; used with COMP/BAL to add external capacitor for bandwidth control |
| OUT (Pin 6) | Amplifier output | Capable of ±12 V swing into 600 Ω; includes short-circuit protection and can drive capacitive loads up to 100 pF |
| VCC+ (Pin 7) | Positive supply | Reference for internal biasing; must be ≥ +3 V and ≤ +22 V; requires local 0.1-μF ceramic bypass to ground |
| COMP/BAL (Pin 8) | Shared compensation/offset node | Configurable as either offset null reference (with BALANCE) or compensation feedback point (with COMP) |
Key Features
| Feature | Design Value |
|---|---|
| Low harmonic distortion | 0.9 dB average noise figure @ 10 Hz–20 kHz - preserves signal fidelity in high-end audio preamps and analog synthesizers |
| External compensation capability | COMP and COMP/BAL pins enable adjustable dominant-pole compensation - allows optimization for specific closed-loop gain and load capacitance |
| Offset nulling capability | BALANCE and COMP/BAL pins support <1 mV residual offset after trimming - critical for DC-coupled medical sensor front-ends |
| Wide supply range | Operates from ±3 V to ±20 V - eliminates need for separate rail generators in mixed-voltage industrial control systems |
| Input protection diodes | Integrated clamping diodes on IN+ and IN− - withstand ±30 mA input current without damage during ESD or overvoltage events |

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 |
|---|---|---|---|
| NE5534P | Same pinout and electrical specs, but rated only for 0°C to +70°C industrial temperature range | Not qualified for automotive or extended-temperature industrial deployments requiring –40°C startup | Select NE5534P only for cost-sensitive commercial-grade audio equipment where ambient temperature stays within 0–70°C |
| OPA1612AIDR | FET-input architecture (0.1 pA IB), lower noise (1.1 nV/√Hz), but no BALANCE/COMP-BAL pins for offset or compensation tuning | Lacks external nulling and compensation flexibility - unsuitable for precision DC servo or legacy audio designs requiring manual trim | Choose OPA1612AIDR for ultra-low-current sensor interfaces or battery-powered audio where offset drift is less critical than input bias |
Compared with NE5534P and OPA1612AIDR, SA5534P uniquely combines extended temperature operation, bipolar low-noise performance, and full external offset/compensation control - making it the only choice for repair, replacement, or new design in legacy audio infrastructure and industrial control systems requiring field-adjustable calibration.

FAQ
What is the maximum supply voltage for SA5534P?
The absolute maximum supply voltage for SA5534P is ±22 V, but the recommended operating range is ±3 V to ±20 V per the datasheet. Exceeding ±22 V risks permanent damage to internal junctions. For reliable long-term operation at ±18 V, ensure thermal dissipation remains within limits using the specified θJA of 85°C/W for the PDIP package. SA5534P must never operate beyond these boundaries without derating.
Does SA5534P require external compensation capacitors?
SA5534P is internally compensated for stable operation at closed-loop gains ≥3, so no external capacitor is required for basic use. However, the COMP and COMP/BAL pins allow optional external capacitor insertion (e.g., 22 pF) to adjust bandwidth and phase margin for higher-gain or capacitive-load applications. This flexibility makes SA5534P adaptable to both general-purpose and precision-tuned designs without changing the IC itself.
How do I perform offset nulling on SA5534P?
To null offset on SA5534P, connect a 10-kΩ potentiometer between BALANCE (Pin 1) and COMP/BAL (Pin 8), with its wiper grounded. Adjust the pot until output voltage equals zero with inputs shorted and supplies applied. This procedure corrects input offset voltage to <1 mV and is essential for DC-coupled applications like ECG front-ends or precision integrators where drift must be minimized. Do not leave BALANCE or COMP/BAL floating.
Is SA5534P pin-compatible with NE5534P?
Yes, SA5534P is pin-compatible with NE5534P - both use identical 8-pin PDIP packaging and share identical pin functions, electrical characteristics, and internal architecture. The sole difference is the extended –40°C to +85°C operating temperature range of SA5534P versus the 0°C to +70°C range of NE5534P. No PCB layout changes are needed when substituting SA5534P for NE5534P in existing designs requiring wider thermal margins.
What is the typical output swing of SA5534P into a 600-Ω load?
At ±18 V supply and TA = 25°C, SA5534P delivers a typical peak-to-peak output voltage swing of 32 V into a 600-Ω load - meaning it can swing from approximately –14.5 V to +14.5 V. This exceeds the 30 VPP minimum and supports professional audio line-driving standards. Performance degrades slightly at temperature extremes or higher loads; always verify swing under actual operating conditions using the datasheet's VO(PP) curves.
