The PA08 is a high voltage power operational amplifier designed for output voltage swings up to ±145 V with a dual supply, or a 290 V single supply. This power amplifier delivers high accuracy via a cascode input circuit configuration. All internal biasing is referenced to a zener diode fed by a FET constant current source. As a result, the PA08 features an unprecedented supply range and excellent supply rejection. Target applications for this POA include electrostatic transducers, deflection circuits and programmable power supplies.
The PA08A is the A grade version providing enhance performance in the areas of offset voltage, offset current and bias current. The PA08V is the extended supply range version (350 V). The PA08M/883 is the fully-certified military grade version. The PA08 series is a hybrid product design housed in an electrically isolated, hermetically sealed 8-pin TO-3 metal package. For continuous operation under load, a heatsink of proper rating is recommended.
