Product details
Overview
SA5534PSG4 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 ±32 V peak-to-peak output swing (at ±18 V supply, RL = 600 Ω), operating across –40°C to +85°C industrial temperature range in an SO (PS) 8-pin package.
For engineers reviewing the SA5534PSG4 datasheet, SA5534PSG4 pinout, SA5534PSG4 application, or SA5534PSG4 equivalent, key selection considerations include its external compensation capability via COMP/COMP-BAL pins, offset nulling support, wide ±3 V to ±20 V supply range, and suitability for low-distortion analog front-ends requiring stable DC performance and high slew rate (13 V/μs).
Technical Context
The SA5534PSG4 is internally compensated for closed-loop gains ≥3 but supports external frequency compensation between COMP and COMP/BAL terminals to optimize bandwidth and stability for specific gain configurations. Its bipolar input stage enables low input bias current (20–300 nA typ) and high common-mode rejection (100 dB typ), while the dual-supply architecture supports true rail-swing operation with ±12 V output swing at ±15 V supplies.
Offset voltage nulling is implemented using the BALANCE and COMP/BAL pins with an external potentiometer, enabling precise trimming of input offset (0.5–4 mV typ). The device features built-in input protection diodes, output short-circuit protection, and operates reliably under recommended conditions of ±5 V to ±15 V supply and –40°C to +85°C ambient temperature.

| IN+ (Pin 3) | Noninverting input | Differential input node; used for unity-gain buffers and noninverting gain stages |
| VCC− (Pin 4) | Negative supply rail | Reference for internal biasing; must be decoupled with 0.1 µF ceramic capacitor near pin |
| COMP (Pin 5) | Compensation output | Provides access to internal compensation node for external capacitor-based bandwidth tuning |
| OUT (Pin 6) | Amplifier output | Low-impedance buffered output capable of driving 600 Ω loads with <0.002% THD |
| VCC+ (Pin 7) | Positive supply rail | Reference for internal biasing; requires local 0.1 µF ceramic bypass to ground |
| COMP/BAL (Pin 8) | Shared compensation/offset node | Configurable as either external compensation point (with Pin 5) or second offset null terminal |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5534DR | Same core architecture but rated for 0°C to +70°C; lower temp grade and SOIC-D (4.90 × 3.91 mm) package | Restricted to commercial-grade equipment; not suitable for extended-temperature industrial deployments | Select NE5534DR only when ambient operating temperature remains within 0–70°C and board space permits smaller SOIC footprint |
| OPA1611AIDR | Lower noise (1.1 nV/√Hz), higher GBW (40 MHz), but no external compensation or offset null pins; DSO-8 package | Optimized for fixed-gain, high-speed audio; lacks trimmable offset and flexible compensation for variable-gain designs | Choose OPA1611AIDR when ultimate noise performance is critical and offset trimming is handled digitally or upstream |
Compared with SA5534PSG4, NE5534DR offers identical electrical behavior at lower cost but sacrifices industrial temperature range and uses a physically smaller SOIC package, while OPA1611AIDR delivers superior noise and speed but removes analog offset adjustment and external compensation-key features for field-serviceable or multi-gain analog systems.

FAQ
What is the maximum supply voltage for SA5534PSG4?
The absolute maximum supply voltage for SA5534PSG4 is ±22 V, but the recommended operating range is ±3 V to ±20 V. Operation beyond ±22 V risks permanent damage. For reliable long-term use, TI specifies ±5 V to ±15 V as the optimal range, especially when driving 600 Ω loads. Always apply 0.1 µF ceramic bypass capacitors at VCC+ and VCC− pins per the layout guidelines in the SA5534PSG4 datasheet.
Does SA5534PSG4 support unity-gain stable operation?
SA5534PSG4 is internally compensated for closed-loop gains ≥3 and is not unity-gain stable by default. However, it supports external compensation via a capacitor between Pins 5 (COMP) and 8 (COMP/BAL) to achieve stable operation at gain = 1. The typical value used is 22 pF, which yields 10 MHz unity-gain bandwidth and controlled phase margin. This configuration is validated in TI's SLOS070D datasheet Figure 10.
How do I perform offset nulling on SA5534PSG4?
Offset nulling on SA5534PSG4 uses Pins 1 (BALANCE) and 8 (COMP/BAL) with a 10 kΩ potentiometer: connect the wiper to Pin 1 and both ends to Pins 8 and ground (or VCC−). Adjust the pot until output voltage equals mid-supply under zero-input conditions. This trims input offset voltage (typically 0.5–4 mV) to sub-millivolt levels. Avoid floating either pin-always terminate both ends of the potentiometer.
What is the thermal resistance (θJA) of the SA5534PSG4 PS package?
The SA5534PSG4 in the SO (PS) 8-pin package has a junction-to-ambient thermal resistance (θJA) of 95°C/W, as specified in TI's SLOS070D datasheet Section 7.4. This value assumes standard JEDEC 2-layer board conditions. For sustained operation near maximum dissipation, ensure adequate copper area and airflow, and verify junction temperature stays below 150°C using TJ = TA + (PD × θJA), where PD is calculated from supply current and output loading.
Is SA5534PSG4 RoHS compliant and lead-free?
Yes, SA5534PSG4 is RoHS compliant and features lead-free (NIPDAU) termination, as confirmed in TI's PACKAGE OPTION ADDENDUM. It carries MSL Level-1 (260°C peak reflow, unlimited floor life) and is qualified for Pb-free soldering processes. The part marking "SA5534" appears on the top surface, and full compliance documentation-including material declarations and test reports-is available through TI's Quality & Environmental Information portal.
