Product details
Overview
SA5532ADR from Texas Instruments is a dual low-noise operational amplifier designed for high-fidelity audio and precision analog signal conditioning. It delivers 5 nV/√Hz input noise voltage at 1 kHz, 12 MHz unity-gain bandwidth, 100 dB common-mode rejection ratio, and 5 V/μs slew rate, operating across –40°C to +85°C in SOIC-8 packaging for pro audio mixers and video infrastructure systems.
For engineers reviewing the SA5532ADR datasheet, SA5532ADR pinout, SA5532ADR application, or SA5532ADR equivalent, this page provides verified electrical characteristics, thermal limits, supply voltage ranges, noise performance, and functional pin mapping - all confirmed for the SA5532ADR variant with industrial temperature grade and SOIC-8 package.
Technical Context
The SA5532ADR integrates two internally compensated op-amps optimized for unity-gain stability, featuring input protection diodes and output short-circuit protection. Its bipolar input stage enables low input bias current (200–800 nA typ) and high DC voltage gain (100 V/mV typ), supporting precision DC-coupled amplification.
It operates from dual supplies of ±5 V to ±15 V, with specified common-mode input range of ±12 V and output swing limited by supply rails. The device exhibits 6–16 mA total supply current and 97 °C/W junction-to-ambient thermal resistance in SOIC-8 (D) package.
Key Specifications

| Common-Mode Rejection Ratio | 100 dB typ - rejects power-supply ripple and EMI coupling in differential sensing | Slew Rate | 5 V/μs typ - preserves transient fidelity in fast-slewing audio waveforms and video sync signals |
| Supply Voltage Range | ±5 V to ±15 V - compatible with standard dual-rail analog supply architectures |
| Operating Temperature | –40°C to +85°C - qualified for industrial and broadcast equipment environments |
| Total Supply Current | 6–16 mA - balances low-power operation with high-output-drive capability |
Pinout & Package
SA5532ADR is housed in an 8-pin SOIC (D) package measuring 4.90 mm × 3.91 mm, with gull-wing leads and RoHS-compliant NiPdAu plating. It features exposed pad-free construction and meets MSL Level-1 reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Output | Amplified signal from Channel 1; capable of ±10 V swing into 600 Ω load |
| 2 (1IN–) | Input | Inverting input for Channel 1; accepts differential or single-ended feedback configurations |
| 3 (1IN+) | Input | Noninverting input for Channel 1; protected by internal clamping diodes |
| 4 (VCC–) | Power | Negative supply rail connection; must be decoupled with 0.1 μF ceramic capacitor |
| 5 (2IN+) | Input | Noninverting input for Channel 2; electrically isolated from Channel 1 inputs |
| 6 (2IN–) | Input | Inverting input for Channel 2; supports independent gain-setting resistor networks |
| 7 (OUT2) | Output | Amplified signal from Channel 2; shares same output drive specs as OUT1 |
| 8 (VCC+) | Power | Positive supply rail connection; requires local bypassing to minimize PSRR degradation |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Noise | 5 nV/√Hz at 1 kHz - critical for microphone preamps and sensor front-ends where SNR dominates system performance |
| High DC Gain | 100 V/mV (100 dB) - ensures minimal gain error in precision instrumentation and active filters |
| Internal Unity-Gain Compensation | Stable at closed-loop gains ≥ 1 - eliminates need for external compensation components in most applications |
| Output Short-Circuit Protection | Withstands indefinite short to either rail - enhances reliability in field-deployed audio and video gear |
| Input Protection Diodes | Clamp input voltage to within ±0.6 V of rails - prevents latch-up during overvoltage transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-noise op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532ADR | Same architecture but rated for 0°C to +70°C only; slightly higher input offset voltage (max 5 mV vs 4 mV) | Restricted to commercial-grade audio equipment; not qualified for industrial thermal cycling | Select NE5532ADR only when ambient temperature remains within 0–70°C and cost sensitivity outweighs extended temp requirement |
| OPA2134PA | FET-input topology; lower input bias current (1 pA vs 800 nA), higher input impedance (10¹² Ω), but higher noise (8 nV/√Hz) | Better for high-Z sensor interfaces (e.g., piezoelectric pickups); less optimal for low-impedance audio lines | Choose OPA2134PA when ultra-low input current is mandatory and noise budget allows 3 nV/√Hz penalty |
Compared with NE5532ADR and OPA2134PA, the SA5532ADR uniquely combines industrial temperature range, bipolar-input low noise, and robust output drive - making it the preferred choice for mission-critical broadcast and embedded audio where thermal stability and SNR are co-constrained.

FAQ
What is the maximum supply voltage for SA5532ADR?
The SA5532ADR supports dual supply voltages from ±5 V to ±15 V. Absolute maximum ratings specify ±18 V on VCC+ and VCC–, but operation beyond ±15 V risks exceeding thermal limits and degrading long-term reliability. TI recommends staying within ±15 V for continuous operation with full specification compliance.
Does SA5532ADR require external compensation capacitors?
No, the SA5532ADR is internally compensated for unity-gain stability and does not require external compensation capacitors. This simplifies PCB layout and ensures predictable phase margin across all closed-loop gains ≥ 1, including inverting and non-inverting configurations with standard feedback networks.
How does SA5532ADR differ from NE5532ADR in thermal performance?
Both SA5532ADR and NE5532ADR use identical SOIC-8 (D) packaging with 97 °C/W junction-to-ambient thermal resistance. However, SA5532ADR's extended –40°C to +85°C operating range requires derating total supply current above +70°C to maintain TJ ≤ 150°C, whereas NE5532ADR is only specified up to +70°C.
Can SA5532ADR drive 600 Ω loads effectively?
Yes, the SA5532ADR delivers ±10 V output swing into 600 Ω loads under ±15 V supplies, with distortion maintained below 0.003% THD+N at 1 kHz. Its high output current capability (38 mA short-circuit current) ensures stable operation into reactive or low-impedance audio loads without oscillation or clipping.
Is SA5532ADR pin-compatible with SA5532AD?
Yes, SA5532ADR and SA5532AD share identical SOIC-8 pinout, electrical specifications, and functional behavior. The "R" suffix denotes tape-and-reel packaging (2500 units/reel), while SA5532AD is obsolete and no longer in production - SA5532ADR is the active, recommended replacement with same pinout and performance.
