Apex Microtechnology's PA07R, a Radiation Tolerant Power Amplifier

The PA07R is a high voltage, high output current operational amplifier designed to drive resistive, inductive, and capacitive loads. For optimum linearity, especially at low levels, the output stage is biased for class A/B operation using a thermistor compensated base-emitter voltage multiplier circuit. A thermal shutoff circuit protects against overheating and minimizes heatsink requirements for abnormal operating conditions. The safe operating area (SOA) can be observed for all operating conditions by selection of user programmable current limiting resistors. The amplifier is internally compensated for all gain settings. For continuous operation under load, a heatsink of proper rating is recommended.

Apex Microtechnology's radiation tolerant devices are tested to maintain operability after exposure to certain levels of radiation. Apex's RT devices include radiation data for HDR, ELDRS, and SEE testing in addition to TID lot traceability and PIND data.
