Description
●Since J-FET input operational amplifiers are formed from a pair of J-FET transistors, they provide superlative characteristics, including a high input impedance and a low input bias current. Thus they can be used in a wide range of applications, from general-purpose control equipment to medical applications. In particular, they are optimal for processing signals from high-impedance sensors.
●Hitachi J-FET input operational amplifiers are available in single, dual, and quad versions. Other than the HA17080, all products are internal phase compensation types and include a built-in phase compensation capacitor. The HA17080 and the HA17083 allow offset adjustment. These products are also available in “A” grade versions with superlative electrical characteristics to allow the selection of an operational amplifier appropriate for the application.
