General Description

The Supertex HV440 is a monolithic integrated circuit capable of generating up to 70V RMS sine wave output at frequencies of 15Hz to 60Hz with a load of 5 North American RENs. Its output rating can be enhanced to 20 North American RENs with the addition of two Supertex MOSFETs: one N-Channel MOSFET, the TN2524N8 and one P-Channel MOSFET, the TP2522N8.
