μPC844, μPC4744 are high-speed version of the single-power general-purpose operational amplifier μPC451, μPC324 realizing high-speed response and high stability. By adopting a High-Speed PNP transistor circuit, various characteristics such as slew rate and gain bandwidth are improved, as compared to μPC451 and μPC324, the load capacity stability is also improved, with no crossover distortion. It can be used widely for various application circuits such as single power supply AC amplifier, active filter, line driver, amplifier for light receiving element, etc. Depending on the usage and operating ambient temperature range, the μPC844 is designed for extended temperature and suited for wide operating ambient temperature application, and μPC4744 is design for general purposes. Along with this series of lineup, the dual type operational amplifier, µPC842, μPC4742 with the same circuit configuration are also available.
