Sp491een купить от 44,00 руб.

sp491een, also known as the STMicroelectronics SP491EN, is a monolithic integrated circuit that was first introduced in 1979. It is a quadruple op-amp that is widely used for audio applications, including guitar and bass amplifiers, preamplifiers, and other audio equipment.

The SP491EN is a low-cost solution for audio amplifiers that needs four op-amps. This device has a wide supply voltage range from ±5 V to ±35 V. The output swing is ±12 V, which makes it ideal for driving low impedance loads. The device is available in a 14-pin DIP package.

One of the most popular applications for the SP491EN amplifier is guitar cabinets. Guitar cabinets require a lot of power, so using four op-amps is the best choice for this application. The SP499EN has a very low distortion level, which is important for professional guitarists.

Another application for the SP491EN is preamplifiers. Preamplifiers are used to amplify the signal before it goes to the main amplifier. The SP499EN is a great choice for preamplifier because it has a high slew rate and low noise.

In conclusion, the SP491EN op-amp is a great solution for audio applications. It has a wide range of supply voltages and can drive low impedance loads well. The SP491EN has been used in many guitar cabinets and preamplifiers over the years, and it is still one of the best options for these types of applications.
