The μPC258 and 4558 are dual operational amplifier with a built-in phase compensation circuit, feature High-Speed, wide band and low noise. Therefore, applications such as active filters, audio amplifiers and VCOs can be realized with a simple circuit configuration. Depending on the operating ambient temperature, µPC258 is suitable for communication application while µPC4558 is suitable for general-purpose usage. In addition, special arrangement products with sorted DC items are available. Along with this series of lineup, the quad type op-amp µPC458 and 4741 with same circuit configuration are also available.
