... High accuracy is achieved with a cascode input circuit configuration. All internal biasing is referenced to a bootstrapped zener-MOSFET cur- rent source result, the PA98 features an unprec- edented supply range and excellent supply rejection. The MOSFET output stage is biased on for linear oper- ation ...

... TEMPERATURE, junction TEMPERATURE RANGE, storage OPERATING TEMPERATURE RANGE, case CAUTION The PA98 is constructed from MOSFET transistors. ESD handling procedures must be observed. The exposed substrate contains beryllia (BeO). Do not crush, machine, or subject to temperatures in excess of 850°C to avoid generating toxic fumes. SPECIFICATIONS Test Condi- ...

... Full temp range TEMPERATURE RANGE, case Meets full range specifications NOTES: * The specification of PA98A is identical to the specification for PA98 in applicable column to the left. 1. Unless otherwise noted: T are ± value given. Power supply voltage is typical rating. 2. Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power dissipation to achieve high MTTF ...

... INTERNAL POWER DISSIPATION AND HEATSINK SELECTION With the unique combination of high voltage and speed of the PA98, traditional formulas for heatsink selection will falsely lower the apparent power handling capability of this amplifier. To predict operating temperatures use the following procedure: Find internal dissipation (PD) resulting from driving the load ...
