 PA13 Data Sheet

The PA13 is a 15A, 90V power operational amplifier with low thermal resistance (1.1°C/W). Target applications include driving resistive, inductive and capacitive loads such as motors, magnetic deflection, transducers, and programmable power supplies.

For optimum linearity, especially at low levels, the output stage is biased for Class A/B operation by using a thermistor compensated base emitter voltage multiplier circuit. The safe operating area (SOA) can be observed for all operating conditions by selection of user programmable current limit resistors, and the amplifier is internally compensated for all gain settings. The PA13 is not recommended for gains below –3 (inverting) or +4 (non-inverting).

The PA13A is the A grade version providing enhance performance in the areas of offset voltage, offset current and bias current. The PA13 series is a hybrid product design housed in an electrically isolated 12-pin PowerSIP package. For continuous operation under load, a heatsink of proper rating is recommended.
