Using a highly reliable cascaded architecture, Apex Microtechnology has introduced a power amplifier that meets the power supply and test equipment markets' demand for higher voltage amplifiers with a small form factor. The PA99 is capable of operating on a maximum voltage supply of 2500V and provides output voltages beyond 2400VPP.

Based on its MP108FD power op amp, Apex Microtechnology has released a next-gen open frame POA, the MP118FD. The MP118FD mirrors the high current and high voltage performance features of the MP108FD, adding a more comprehensive set of circuit protection capabilities, along with better thermal efficiency. Apex expects that customers using the MP118FD will find even more to like when it comes to driving piezo transducer applications.
