The PA12 is a 15 A, 100 V power operational amplifier with low thermal resistance (1.4°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 PA12 is not recommended for gains below –3 (inverting) or +4 (non-inverting).
The PA12A is the A grade version providing enhance performance in the areas of offset voltage, offset current and bias current. The PA12H is a high temperature version for use in extreme operating environments. The PA12M/883 is the fully-certified military grade version. The PA12 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.
