Product details
Overview
SA5534PSE4 from Texas Instruments is a precision, low-noise operational amplifier in an 8-pin PDIP package, featuring 3.5 nV/√Hz input noise voltage, 10 MHz unity-gain bandwidth, and 13 V/μs slew rate. It operates across ±3 V to ±20 V supplies, delivers ±32 V peak-to-peak output swing at ±18 V, and supports offset nulling and external frequency compensation - widely deployed in high-fidelity audio preamplifiers and medical instrumentation signal chains.
For engineers reviewing the SA5534PSE4 datasheet, SA5534PSE4 pinout, SA5534PSE4 application, or SA5534PSE4 equivalent, this page provides verified technical context, real-world design meaning for key specs, validated pin functions, confirmed alternatives with functional distinctions, and supply support tailored for industrial and medical analog systems requiring stable, long-lifecycle op-amps.
Technical Context
The SA5534PSE4 is internally compensated for closed-loop gains ≥3 and supports external compensation via the COMP and COMP/BAL pins to optimize bandwidth and stability for specific gain configurations. Its bipolar input stage delivers low input bias current (20–300 nA typ) and high DC voltage gain (100 V/mV typ), enabling precision DC-coupled amplification without significant drift.
It features dual supply operation (±3 V to ±20 V), rail-to-rail output drive into 600 Ω loads, and robust protection including input diodes and output short-circuit tolerance. The extended temperature range (–40°C to +85°C) and specified noise performance distinguish it from the commercial-grade NE5534 series.
Key Specifications

Pinout & Package
SA5534PSE4 is housed in an 8-pin plastic dual in-line package (PDIP), 0.300-inch body width, with through-hole mounting and industry-standard pin spacing (0.100" pitch). Thermal resistance θJA = 85°C/W enables reliable operation at up to 700 mW dissipation in typical PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BALANCE (Pin 1) | Offset null adjustment terminal | Connects to one end of a 10 kΩ potentiometer for manual input offset voltage trimming - critical for DC-precision applications like medical front-ends. |
| IN− (Pin 2) | Inverting input | Primary feedback node in inverting amplifier configurations; accepts signals referenced to system ground or virtual ground. |
| IN+ (Pin 3) | Noninverting input | High-impedance input for unity-gain buffers or noninverting amplifiers; sensitive to layout-induced noise and requires guard ringing. |
| VCC− (Pin 4) | Negative supply rail | Must be bypassed with 0.1 µF ceramic capacitor near the pin to suppress power-supply noise coupling into the input stage. |
| COMP (Pin 5) | Compensation output | Provides internal compensation node access; used with COMP/BAL to configure external frequency compensation networks. |
| OUT (Pin 6) | Amplifier output | Capable of driving 600 Ω loads directly; output short-circuit protected but requires thermal derating above 70°C ambient. |
| VCC+ (Pin 7) | Positive supply rail | Paired with VCC− for dual-supply operation; supports single-supply use with appropriate level-shifting and biasing. |
| COMP/BAL (Pin 8) | Shared compensation/offset node | Connects to other end of offset null pot or to external capacitor for gain-dependent bandwidth shaping - enables custom stability tuning. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise bipolar input stage | 3.5 nV/√Hz input voltage noise enables clean amplification of microvolt-level signals from condenser mics or biopotential electrodes. |
| External frequency compensation | COMP and COMP/BAL pins allow precise bandwidth and phase-margin control - essential for stable high-gain (>10×) or capacitive-load applications. |
| Offset voltage nulling capability | BALANCE and COMP/BAL pins support <1 mV residual offset after trimming - required for DC-coupled servo loops and precision instrumentation. |
| High output drive into 600 Ω | Delivers >25 mA continuous output current - drives professional audio line outputs, ADC drivers, and active filters without external buffers. |
| Extended temperature qualification | Specified over –40°C to +85°C - suitable for deployment in uncontrolled environments such as factory-floor controllers or portable diagnostic gear. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5534P | Commercial temperature range (0°C to 70°C); identical pinout, noise (3.5 nV/√Hz), and bandwidth (10 MHz). | Limited to indoor, climate-controlled systems - unsuitable for automotive, outdoor, or medical field equipment. | Select NE5534P only when cost sensitivity outweighs environmental qualification needs and ambient stays within 0–70°C. |
| OPA1611AIDR | FET-input architecture (0.2 pA bias current), lower noise (1.1 nV/√Hz), but higher quiescent current (3.6 mA vs. 8 mA) and no offset-null pins. | Better for ultra-high-Z sources (piezo sensors, photodiode TIA), but lacks BALANCE/COMP/BAL for manual trimming or custom compensation. | Choose OPA1611AIDR when lowest possible noise and input bias dominate; avoid when offset trimming or legacy compensation network compatibility is required. |
Compared with NE5534P and OPA1611AIDR, SA5534PSE4 uniquely combines extended temperature operation, offset-null capability, and proven bipolar noise performance - making it the preferred choice for ruggedized, serviceable analog systems where long-term calibration stability matters.

FAQ
What is the maximum supply voltage for SA5534PSE4?
The absolute maximum supply voltage for SA5534PSE4 is ±22 V, but the recommended operating range is ±3 V to ±20 V per the datasheet. Operation beyond ±20 V risks permanent damage and violates TI's specified safe operating area. For reliable long-term use in medical or industrial applications, staying within ±15 V is advised to maintain thermal margin and ensure 100% parametric compliance across –40°C to +85°C.
Does SA5534PSE4 support single-supply operation?
Yes, SA5534PSE4 can operate from a single supply (e.g., +15 V and ground), but its input common-mode range extends only to within ~3 V of the negative rail - so a proper input bias network (e.g., resistive divider) and output level-shifting are required. Unlike rail-to-rail op-amps, SA5534PSE4 does not swing fully to either rail; its output remains ~2 V away from each supply, necessitating careful headroom planning in single-supply designs.
How do I configure external compensation for SA5534PSE4?
Connect a capacitor (typically 22–47 pF) between Pin 5 (COMP) and Pin 8 (COMP/BAL) to adjust unity-gain bandwidth and phase margin. Increasing capacitance reduces bandwidth and improves stability at high closed-loop gains; decreasing it raises bandwidth but may induce peaking. TI's SLOS070D datasheet Figure 10 shows the standard configuration, and the device remains stable for gains ≥3 without external compensation.
What is the purpose of the BALANCE and COMP/BAL pins on SA5534PSE4?
The BALANCE (Pin 1) and COMP/BAL (Pin 8) pins enable two distinct functions: BALANCE serves as one terminal for a 10 kΩ potentiometer used to null input offset voltage, while COMP/BAL acts as the second terminal - either for offset trimming or as the return node for external compensation capacitors. This dual-role design allows designers to retain offset adjustability even when using external frequency compensation.
Is SA5534PSE4 RoHS-compliant?
Yes, SA5534PSE4 is RoHS-compliant, as confirmed by Texas Instruments' packaging addendum: it carries "Yes" in the RoHS column and uses NiPdAu (NIPDAU) lead finish. The part marking "SA5534P" appears on the package, and the "E4" suffix denotes TI's green, lead-free, RoHS-compliant packaging standard - verified for use in medical and industrial products requiring full substance compliance documentation.
