Product details
Overview
SA5534PS 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 and –40°C to +85°C industrial temperature range.
For engineers reviewing the SA5534PS datasheet, SA5534PS pinout, SA5534PS application, or SA5534PS equivalent, this page provides verified specifications, SO (PS) package details, offset-nulling and external compensation capabilities, and validated alternatives for audio, medical, and servo amplifier designs.
Technical Context
The SA5534PS is internally compensated for stable operation at gain ≥ 3, with dedicated BALANCE and COMP/BAL pins enabling precise offset nulling and frequency response tailoring via external capacitor. Its bipolar input stage delivers low input bias current (20–300 nA typ) and high DC voltage gain (100 V/mV typ).
It features input protection diodes, output short-circuit protection, and operates across ±3 V to ±20 V supplies. The SO (PS) package supports surface-mount assembly with Level-1 moisture sensitivity and 2000-unit tape-and-reel packaging.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5534DR | Commercial-grade (0°C to 70°C); identical electrical specs but narrower temp range and SOIC (D) package | Limited to ambient-temperature consumer or lab equipment; not suitable for industrial enclosures | Select NE5534DR only when cost-sensitive and operating within 0–70°C; SA5534PS offers broader thermal margin |
| OPA1611AIDR | Lower noise (1.1 nV/√Hz), rail-to-rail output, but higher quiescent current (3.6 mA vs 8 mA) and no external compensation pins | Superior SNR for ultra-high-end audio; lacks BALANCE/COMP pins needed for precision DC servo loops | Choose OPA1611AIDR for noise-critical AC-coupled audio; retain SA5534PS where offset nulling or custom compensation is required |
Compared with NE5534DR and OPA1611AIDR, the SA5534PS uniquely combines industrial temperature range, external compensation flexibility, and proven low-noise performance-making it the preferred choice for servo, medical, and ruggedized audio systems demanding long-term DC stability and thermal robustness.

FAQ
What is the maximum supply voltage for SA5534PS?
The absolute maximum supply voltage for SA5534PS is ±22 V, but the recommended operating range is ±3 V to ±20 V per TI's SLOS070D datasheet. Exceeding ±22 V risks permanent damage. For reliable long-term operation, maintain supply rails within ±18 V, especially when driving 600 Ω loads where peak output swing reaches ±14 V.
Does SA5534PS support single-supply operation?
Yes, SA5534PS 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 single-supply use, bias the IN+ pin at mid-rail (e.g., 6 V) and AC-couple inputs/outputs. Dual-supply operation (±15 V) is preferred to fully exploit its ±13 V common-mode range and maximize dynamic headroom.
How do I configure external compensation on SA5534PS?
To configure external compensation on SA5534PS, 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 for gains below 3. Do not connect the capacitor directly to ground or supply rails-TI's SLOS070D Figure 10 shows the correct configuration. Avoid values >100 pF unless stability analysis confirms margin.
What is the purpose of the BALANCE and COMP/BAL pins on SA5534PS?
The BALANCE (Pin 1) and COMP/BAL (Pin 8) pins on SA5534PS serve dual functions: BALANCE is used with a potentiometer (10–50 kΩ) across Pins 1 and 8 to null input offset voltage; COMP/BAL doubles as the second terminal for that potentiometer or as the return node for the external compensation capacitor connected to Pin 5. Both pins must be actively configured-leaving them floating degrades DC accuracy and stability.
Is SA5534PS pin-compatible with NE5534 or SA5534A variants?
SA5534PS is pin-compatible with all 8-pin variants in the 5534 family-including NE5534, NE5534A, SA5534, and SA5534A-because they share identical SO (PS), SOIC (D), and PDIP (P) footprints and pinouts. However, SA5534PS is rated for –40°C to +85°C, while NE5534 variants are limited to 0°C to +70°C. Electrical specs are identical except for guaranteed max input noise voltage, which is tighter for 'A' versions.
