Texas Instruments NE5532PSR

Overview

NE5532PSR 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 from ±5 V to ±15 V supplies across 0°C to 70°C. It is widely deployed in pro audio mixers and AV receivers where low distortion and wide dynamic range are critical.

For engineers reviewing the NE5532PSR datasheet, NE5532PSR pinout, NE5532PSR application, or NE5532PSR equivalent, key selection criteria include verified input noise performance, guaranteed unity-gain stability, dual-supply rail compatibility, thermal derating under continuous load, and SO package (PS) mechanical footprint compliance with IPC-7351B.

Technical Context

The NE5532PSR integrates two internally compensated op-amps optimized for unity-gain stability with fully differential input stages and short-circuit protected outputs. Its architecture supports rail-to-rail output swing within ±13 V of supply rails and maintains ≥100 dB CMRR over its full operating temperature range (0°C to 70°C).

It features input protection diodes, output short-circuit protection, and specified maximum limits for equivalent input noise voltage. The device is not rail-to-rail input but achieves ±12 V common-mode input range with ±15 V supplies, enabling robust operation in legacy audio and instrumentation designs.

Key Specifications

Pinout & Package

NE5532PSR uses an 8-pin SO (PS) package measuring 6.20 mm × 5.30 mm (nominal), compliant with JEDEC MS-012AB and IPC-7351B SOIC-8 standards. It shares pinout compatibility with SOIC (D) and PDIP (P) variants of the NE5532 family.

FAQ

What is the maximum supply voltage for NE5532PSR?

The absolute maximum supply voltage for NE5532PSR is ±18 V, but recommended operating conditions specify ±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 ±0.6 V of the rails, so maintaining supply margins ensures safe operation under transient load conditions. Always verify thermal dissipation using RθJA = 95°C/W for the PS package.

Does NE5532PSR require external compensation for unity-gain operation?

No, NE5532PSR is internally compensated for unity-gain stability and does not require external compensation components. Its dominant-pole compensation ensures phase margin >45° at gain = 1 across all process, voltage, and temperature corners. This allows direct use in voltage followers, active filters, and noninverting buffers without risk of oscillation - a key differentiator from decompensated op-amps like OPA1612 or LM4562.

What is the input common-mode voltage range of NE5532PSR?

At ±15 V supplies, NE5532PSR supports a common-mode input voltage range of ±12 V minimum, extending to ±13 V typical. This means both inputs can operate safely between –12 V and +12 V relative to ground. The range shrinks linearly with reduced supply voltage - e.g., ±10 V supplies yield ~±8 V usable common-mode range. Input protection diodes prevent damage if common-mode exceeds rails by more than 0.6 V.

How does NE5532PSR compare to NE5532DR in terms of thermal performance?

NE5532PSR has a junction-to-ambient thermal resistance (RθJA) of 95°C/W in its SO (PS) package, while NE5532DR in SOIC (D) package measures 97°C/W. Though nearly identical, the PS variant offers marginally better heat dissipation due to larger pad area and copper exposure. Both require 0.1 μF ceramic bypass capacitors at each supply pin and benefit from thermal vias under the exposed pad (if present) to sustain 16 mA total supply current at elevated ambient temperatures.

Is NE5532PSR suitable for single-supply operation?

NE5532PSR is optimized for dual-supply operation (±5 V to ±15 V) and is not characterized for true single-supply use. While it can function with a split virtual ground (e.g., 15 V rail with mid-rail bias), its input common-mode range does not extend to the negative rail, and output swing is asymmetric near ground. For dedicated single-supply applications, TI recommends alternatives like TL072 or OPA1671 - NE5532PSR should only be used in single-rail configurations with careful biasing and verification of headroom margins.
