Product details
Overview
NE5532AD from Texas Instruments is a dual low-noise operational amplifier designed for high-fidelity analog signal conditioning in professional audio and precision instrumentation. It delivers 5nV/√Hz input noise voltage at 1kHz, 12MHz unity-gain bandwidth, 100dB common-mode rejection ratio, 5V/μs slew rate, and operates over 0°C to 70°C with ±5V to ±15V dual supply. It serves as the core gain stage in pro audio mixer channel strips.
For engineers reviewing the NE5532AD datasheet, NE5532AD pinout, NE5532AD application, or NE5532AD equivalent, this page provides verified specifications, SOIC-8 package details, real-world audio and video signal chain use cases, and two validated alternative op-amps with documented functional and thermal differences.
Technical Context
The NE5532AD features internally compensated unity-gain stable architecture with bipolar input stage, enabling robust performance without external compensation. Its dual-channel layout supports independent signal paths with matched dc characteristics (input offset voltage ≤4mV typ) and ac behavior (noise, bandwidth, slew rate).
It operates under dual-supply conditions (±5V to ±15V), with rail-to-rail output swing limited by supply headroom and load, and includes input protection diodes and output short-circuit protection. The device is not rail-to-rail input or output but achieves ±13V common-mode input range and ±12V output swing into 600Ω at ±15V supplies.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-noise operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532DR | Same SOIC-8 package and electrical specs, but NE5532DR lacks the 'A' grade's tighter input offset voltage (5mV max vs 4mV max) and improved noise floor consistency | Acceptable for cost-sensitive consumer audio where <0.5mV offset drift is tolerable; not recommended for DC-coupled studio-grade summing amps | Select NE5532AD when guaranteed 4mV max VIO and production lot consistency are required for calibrated test equipment or OEM audio modules |
| OPA2134PA | FET-input architecture (0.8pA IIB), lower 1/f noise, but higher 1kHz noise (8nV/√Hz); 8MHz GBW; SOIC-8 package | Better for high-impedance sensor interfaces (e.g., piezo pickups); less suitable for driving 600Ω lines due to lower output current and slew rate (2V/μs) | Choose OPA2134PA only when ultra-low input bias current is critical and bandwidth/noise trade-offs are acceptable |
Compared with NE5532DR and OPA2134PA, the NE5532AD delivers optimal balance of low noise, high slew rate, and robust output drive in commercial temperature-grade audio signal chains-making it the preferred choice for volume-manufactured prosumer AV gear where cost, performance, and qualification stability are jointly constrained.

FAQ
What is the maximum supply voltage for NE5532AD?
The NE5532AD supports a maximum supply voltage of ±15V per rail, with absolute maximum ratings specifying ±18V. Operation beyond ±15V risks exceeding thermal limits and degrading long-term reliability. The NE5532AD datasheet explicitly defines ±15V as the upper limit for recommended operating conditions, and all published electrical characteristics-including noise, bandwidth, and slew rate-are guaranteed within this range.
Does NE5532AD support single-supply operation?
The NE5532AD is optimized for dual-supply operation (±5V to ±15V) and does not support true single-supply operation down to ground. Its input common-mode range extends to ±13V and output swing reaches ±12V, but both require symmetric rails. While it can be biased above ground using a virtual ground, the NE5532AD lacks rail-to-rail input/output capability and exhibits degraded PSRR and CMRR in single-supply configurations-making dedicated single-supply op-amps like the TLV2462 preferable for such designs.
What is the input offset voltage specification for NE5532AD?
The NE5532AD has a maximum input offset voltage of 4mV at 25°C, with a typical value of 0.5mV. This parameter is tested across the full commercial temperature range (0°C to 70°C), where the maximum allowable offset increases to 5mV. The 'A' suffix denotes the improved grade over standard NE5532, ensuring tighter initial tolerance and better thermal drift stability-critical for DC-coupled applications like active filters and precision summing amplifiers where offset directly impacts output accuracy.
Is NE5532AD pin-compatible with NE5532DR?
Yes, the NE5532AD is pin-compatible with NE5532DR in the SOIC-8 (D) package, sharing identical pinout, footprint, and thermal pad configuration. Both devices use the same 4.90mm × 3.91mm outline and 1.27mm pitch. However, the NE5532AD offers tighter input offset voltage (4mV max vs 5mV max) and improved noise consistency, so while PCB layout remains unchanged, system-level performance validation is recommended when substituting NE5532DR for NE5532AD in precision audio paths.
What thermal considerations apply to NE5532AD in continuous operation?
The NE5532AD has a junction-to-ambient thermal resistance (RθJA) of 97°C/W in SOIC-8 package. At ±15V supply and no load, total supply current is 16mA, yielding ~480mW dissipation. Under worst-case ambient (70°C), junction temperature reaches ~117°C-within the 150°C absolute maximum. To ensure reliability, maintain ≥25°C margin via adequate copper pour, avoid stacking heat sources, and verify board-level thermal performance using TI's thermal metrics methodology per JEDEC JESD51-7.
