The μPC824 and 4074 are low noise versions operational amplifier of μPC804 and 4084 series with the general-purpose J-FET input. Compared with the μPC804 and 4084 series, various characteristics such as input referred noise, input offset voltage and input bias current have been improved. It is therefore ideal for application circuits such as preamplifiers and active filters for measurement, audio and measurement where low noise, high input impedance and high-speed characteristics are important. Depending on the operating ambient temperature, μPC824 is suitable for communication application while μPC4074 is suitable for general-purpose usage. Along with this series of lineup, the dual type op-amp μPC822 and 4072 with same circuit configuration are also available.
