The NE5532D is a dual low-noise, high-speed audio operational amplifier manufactured by Texas Instruments. It is designed for use in various audio applications including high-end audio, line-level mixing, and headphone amplifiers.The NE5532D features low-noise performance, wide bandwidth, and high slew rates for superior performance. The amplifier offers a typical voltage gain of 106dB, with a low typical supply current of 1.5mA per amplifier. The amplifier is designed for single supply operation, and can operate at a supply voltage range of 4.5V to 18V.The NE5532D also includes an enable/disable pin, which can be used to reduce the total power consumption of the amplifier when both amplifiers are not in use. Additionally, the amplifier is designed with low distortion and maximum output swing capabilities to provide accurate performance. It also includes an optional mute/shutdown control pin which can be used to shut off the amplifier with minimal audio disruption.The NE5532D is designed to meet all applicable standards, and is ideal for high-end audio components and audio mixing applications. It is available in two package options: SOIC-8 or single-in-line packages, which can be used in a variety of applications.
