The PA198 is a 450V power operational amplifier with a very high 2,000V/µs slew rate targeted at high voltage applications including instrumentation, piezoelectric transducers and electrostatic transducers and deflection. Output voltages can swing up to ±215V on dual supplies, and up to +440V single supply. This high voltage amplifier utilizes a MOSFET output stage and has a power bandwidth of up to 2MHz. When operating within a safe operating area, the PA198 has a maximum continuous current of 200mA.
High accuracy is achieved with a cascode input circuit configuration. All internal biasing is referenced to a bootstrapped Zener-MOSFET current source. As a result, the PA198 features an unprecedented supply range and excellent supply rejection. The PA198 series is a hybrid product design housed in a space saving, electrically isolated 12-pin PowerSIP package which lends itself to high-density circuit board layouts.
