Apex Microtechnology PA10 High Temp Power Amplifiers

Apex Microtechnology PA10 High Temp Power Amplifiers are 5A, 100V amplifiers with a 4MHz gain bandwidth. The PA10 are ideal for driving resistive, inductive, and capacitive loads like motors, magnetic deflection, and programmable power supplies. The PA10 offer optimum linearity at low levels, and the output stage is biased in the Class A/B mode. The safe operating area (SOA) is observed for operating conditions by selection of user-programmable current limit resistors, and the amplifier is internally compensated for all gain settings. The PA10A is the A-grade version with enhanced performance in offset voltage, offset current, and bias current. The PA10M/883 is the certified military grade version. The PA10 is 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.
