Product details
Overview
NE5532ADR from Texas Instruments is a dual low-noise operational amplifier designed for high-fidelity audio and precision analog signal conditioning. It delivers 5nV/√Hz input noise voltage at 1kHz, 12MHz unity-gain bandwidth, and 5V/μs slew rate, operating across ±5V to ±15V supplies in 0°C to 70°C ambient. It serves as the core gain stage in pro-audio mixers and AV receiver line-level circuitry.
For engineers reviewing the NE5532ADR datasheet, NE5532ADR pinout, NE5532ADR application, or NE5532ADR equivalent, key selection criteria include its guaranteed 100dB CMRR at 25°C, ±13V common-mode input range, 6–16mA total supply current, and SOIC-8 packaging with NIPDAU lead finish and Level-1 moisture sensitivity rating.
Technical Context
The NE5532ADR is internally compensated for stable unity-gain operation and features input protection diodes plus output short-circuit protection. Its bipolar input stage enables high DC voltage gain (≥10V/mV min) and low input bias current (≤800nA typ), while maintaining rail-to-rail output swing capability under 600Ω load.
It operates exclusively in dual-supply mode with dedicated VCC+ (Pin 8) and VCC– (Pin 4) terminals, supporting symmetrical supply configurations. The device exhibits specified maximum equivalent input noise voltage and meets JEDEC JESD22-C101 CDM ESD rating of 1000V across all pins.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Output | First amplifier output; drives external load directly or feeds next stage with ≥38mA short-circuit capability |
| 2 (1IN–) | Input | Inverting input of first amplifier; accepts feedback network for precise gain setting and stability control |
| 3 (1IN+) | Input | Noninverting input of first amplifier; referenced to ground or bias network for single-ended or differential inputs |
| 4 (VCC–) | Power | Negative supply rail connection; must be decoupled with 0.1μF ceramic capacitor placed ≤2mm from pin |
| 5 (2IN+) | Input | Noninverting input of second amplifier; electrically isolated from first channel for dual independent signal paths |
| 6 (2IN–) | Input | Inverting input of second amplifier; supports inverting configuration, summing junctions, or active filters |
| 7 (OUT2) | Output | Second amplifier output; identical AC/DC performance to OUT1, enabling stereo or dual-channel processing |
| 8 (VCC+) | Power | Positive supply rail connection; requires local 0.1μF bypass to minimize PSRR degradation above 10kHz |
Key Features

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 |
|---|---|---|---|
| NE5532DR | Same electrical specs but unqualified A-grade; input offset voltage max 5mV vs 4mV for NE5532ADR | Acceptable in cost-sensitive consumer audio where tighter VIO not required | Select NE5532DR only when full temperature-range VIO spec (5mV max) suffices and BOM cost reduction is critical |
| OPA2134PA | FET-input architecture; 8nV/√Hz noise, 8MHz GBW, ±13.5V max supply - lower bias current but higher noise than NE5532ADR | Better for high-impedance sensor interfaces; less suitable for low-Z line driving due to lower output current | Choose OPA2134PA when ultra-low input bias (<1pA) is mandatory and 5nV/√Hz noise is not required |
Compared with NE5532DR and OPA2134PA, the NE5532ADR provides the optimal balance of ultra-low noise, high output drive, and proven reliability in commercial audio infrastructure - making it the preferred choice for line-level signal chains demanding both fidelity and robustness.

FAQ
What is the maximum supply voltage for NE5532ADR?
The NE5532ADR supports a maximum supply voltage of ±15V per rail, with absolute maximum ratings specifying ±18V. Operation beyond ±15V violates recommended conditions and risks parametric shift or reliability degradation. The NE5532ADR datasheet explicitly limits continuous operation to ±15V under all temperature conditions, and TI advises against exceeding this value even briefly in production designs.
Does NE5532ADR support single-supply operation?
No, the NE5532ADR is not designed for true single-supply operation. Its input common-mode range extends to ±13V and output swing is optimized for dual ±VCC rails. While it can function with a split virtual ground, the NE5532ADR lacks rail-to-rail input/output capability and requires both positive and negative supplies to meet its specified AC and DC performance - including CMRR, THD, and output swing - across the full temperature range.
What is the meaning of the 'A' suffix in NE5532ADR?
The 'A' in NE5532ADR denotes the improved version of the original NE5532, featuring tighter input offset voltage (4mV max vs 5mV max), enhanced common-mode rejection ratio (100dB typ), and updated thermal and ESD specifications. This 'A' grade is fully backward-compatible with NE5532 footprints and electrical behavior, but offers superior DC precision and noise performance - confirmed in TI's SLOS075K datasheet revision history.
How does NE5532ADR compare to SA5532ADR in terms of temperature range?
The NE5532ADR is rated for 0°C to 70°C operation, whereas the SA5532ADR extends to –40°C to +85°C. Both share identical electrical characteristics (noise, bandwidth, slew rate) at 25°C, but the SA5532ADR guarantees performance across the extended industrial temperature range. For commercial audio equipment operating indoors, the NE5532ADR is sufficient; outdoor or automotive-adjacent applications require SA5532ADR.
Is NE5532ADR RoHS compliant and what is its MSL rating?
Yes, the NE5532ADR is RoHS compliant (lead-free, NIPDAU finish) and carries a Moisture Sensitivity Level (MSL) rating of Level-1 at 260°C peak reflow, meaning it has unlimited floor life and requires no baking prior to soldering. This MSL-1 classification is verified in TI's official Packaging Information addendum and simplifies manufacturing for high-volume SMT lines using standard reflow profiles.
