Texas Instruments NE5532APSRE4

Overview

NE5532APSRE4 from Texas Instruments is a dual low-noise operational amplifier designed for high-fidelity audio signal conditioning and precision analog front-ends. It delivers 5 nV/√Hz input noise voltage at 1 kHz, 12 MHz unity-gain bandwidth, 100 dB common-mode rejection ratio, 5 V/μs slew rate, and operates over ±5 V to ±15 V supplies in 0°C to 70°C ambient. It is widely deployed in pro audio mixers and AV receivers where low distortion and wide dynamic range are critical.

For engineers reviewing the NE5532APSRE4 datasheet, NE5532APSRE4 pinout, NE5532APSRE4 application, or NE5532APSRE4 equivalent, key selection considerations include its SO (PS) 8-pin package, dual-channel configuration, rail-to-rail output swing limitations, thermal performance under continuous load, and compatibility with ±15 V bipolar supply architectures used in legacy and industrial audio systems.

Technical Context

The NE5532APSRE4 integrates two internally compensated op-amps optimized for unity-gain stability, featuring input protection diodes and output short-circuit protection. Its architecture supports both single-supply and dual-supply operation, with specified common-mode input range of ±12 V and output swing within 2 V of rails at ±15 V supply.

It exhibits low distortion across audio frequencies, maintains DC accuracy with 4 mV typical input offset voltage and 150 nA typical input bias current, and achieves stable performance across temperature via internal compensation-enabling direct replacement in legacy NE5532-based designs without external phase compensation networks.

Key Specifications

Pinout & Package

NE5532APSRE4 uses an 8-pin SO (PS) surface-mount package measuring 6.20 mm × 5.30 mm, with gull-wing leads and RoHS-compliant NiPdAu lead finish. It is rated MSL Level-1 (unlimited floor life) and compatible with standard reflow profiles.

FAQ

What is the maximum supply voltage for NE5532APSRE4?

The absolute maximum supply voltage for NE5532APSRE4 is ±18 V, but the recommended operating range is ±5 V to ±15 V. Operation beyond ±15 V risks exceeding thermal limits and degrading long-term reliability. The device's internal protection diodes clamp input voltages to within ±15 V of the supply rails, so maintaining ±15 V ensures optimal noise performance and output swing. NE5532APSRE4 must never be operated at ±22 V, as that exceeds TI's absolute maximum rating and may cause permanent damage.

Does NE5532APSRE4 support single-supply operation?

Yes, NE5532APSRE4 supports single-supply operation, though it is optimized for dual-supply configurations. When used with a single supply (e.g., +15 V and GND), the input common-mode range extends to within 1.5 V of the negative rail (GND), and output swing reaches within 2 V of GND. Biasing the inputs at mid-supply using resistive dividers is required for AC-coupled applications. NE5532APSRE4 retains full functionality-including 12 MHz bandwidth and 5 nV/√Hz noise-in this mode, but DC accuracy depends on proper input referencing.

What is the thermal resistance (θ_JA) of NE5532APSRE4 in its SO (PS) package?

The junction-to-ambient thermal resistance (θ_JA) of NE5532APSRE4 in the SO (PS) 8-pin package is 95°C/W, as specified in TI's thermal information table. This value assumes standard JEDEC test conditions (single-layer board, 1 in² copper pad). In practice, adding thermal vias and a dedicated ground plane reduces effective θ_JA to ~55°C/W. For continuous 16 mA total supply current at ±15 V, power dissipation is ~480 mW-so with θ_JA = 95°C/W, junction temperature rise is ~46°C above ambient. NE5532APSRE4 remains within safe limits up to 70°C ambient.

How does NE5532APSRE4 compare to NE5532A in performance?

NE5532APSRE4 is functionally identical to the NE5532A variant: both share the same 5 nV/√Hz noise, 12 MHz bandwidth, 5 V/μs slew rate, and 0°C to 70°C temperature grade. The "A" suffix denotes improved input offset voltage (4 mV typ vs 5 mV typ for non-A versions) and tighter parameter distributions. NE5532APSRE4 is the tape-and-reel packaged version of NE5532A in SO (PS) form-no electrical or thermal differences exist between NE5532APSRE4 and other NE5532A variants like NE5532ADR. All NE5532A parts meet the same TI specification SLOS075K.

Is NE5532APSRE4 pin-compatible with other NE5532 variants?

Yes, NE5532APSRE4 is pin-compatible with all standard 8-pin NE5532 variants-including NE5532DR (SOIC-D), NE5532AP (PDIP), and NE5532PSR (SO-PS)-because all share identical pin numbering, functions, and electrical behavior per Figure 4-1 and Table 4-1. The SO (PS) package has the same 1.27 mm lead pitch and pinout order as SOIC-D and PDIP. Layout adaptation is required only for footprint dimensions (6.20 mm × 5.30 mm vs 4.90 mm × 3.91 mm), but no schematic or routing changes are needed when substituting NE5532APSRE4 into existing NE5532 designs.
