The NE5532AD is an integrated circuit from Texas Instruments intended for audio amplification. It has two independent, internally compensated high gain operational amplifiers designed specifically to operate from dual-polarity power supplies as low as ±4.5 volts. The device is suitable for applications such as audio preamplifiers, active filters, or as a general audio amplifier.

The NE5532AD is a dual, internally frequency-compensated, low-noise operational amplifier. It is ideal for a number of high performance applications including active filters and audio pre-amplifiers and general audio amplifiers. Two independent amplifiers are incorporated in the SO-8 package, offering high operating current (20 mA per amplifier), a low voltage noise figure, and wide power supply range.

The operational amplifiers feature high-gain and ample open-loop differential voltage. The wide differential voltage gain of NE5532AD enables driving 600 ohm loads for line-level audio. High output current allows for driving capacitive loads with low distortion and without external compensation.

The NE5532AD is a direct replacement for the NE5532A which is designed for high performance line and load driving applications such as active filters and audio pre-amplifiers and general audio amplifiers. The output voltage swing is wide and may be extended to near the supply rails. The high operating current allows for driving capacitive loads with low distortion. The high performance, wide frequency range and low distortion characteristics of the NE5532AD make it especially suitable for driving loads such as headphones, speakers, and other audio transducers.

The NE5532AD has a wide power supply operation range of 4.5 - 18V, and may be operated with supplies ranging from +/-5V to +/-15V. The circuit includes input differential voltage noise canceling and resistive feedback, as well as complementary outputs with current limiting and thermal shutdown. The connection of an external compensation capacitor is required in order to observe amplitude and phase responses over a wide frequency range.

The NE5532AD is a versatile, low-cost component offered from various suppliers, that is easy to use and highly reliable. Its superior performance, low noise figure and excellent output current drive capability make the NE5532AD ideal for a variety of applications in audio processing and signal conditioning. Its wide frequency range, low distortion and excellent power supply rejection ratio make it an ideal choice for high-performance audio systems. Its high performance, wide frequency range and low distortion characteristics make it compatible with various transducers. In addition, its low input offset voltage, low input bias current, wide power supply operating range, and excellent temperature and power supply rejection, provide exceptional system performance.
