High-Voltage, Bipolar Dual Operational Amplifier, Dual-Power Supply, Ultra Low-Noise, High-Speed, Wide Band for Consumer Product

The μPC4570 is a high-performance version of the general-purpose low-noise operational amplifier μPC258, 4558. Various characteristics such as band and slew rate, including input equivalent noise, were greatly improved in comparison to μPC258 and 4558. It is also possible to operate the amplifier with stability for a gain of 1 (total feedback or unity gain). Therefore, it is ideal for application circuits such as audio preamplifiers, equalizers, tone controls, and active filters. Under this product series, there is also a quad type (μPC4574) with equivalent characteristics.
