New Surface Mount Amplifiers Break Barriers For Price And Performance
Apex Microtechnology introduces the PA38 and PA39, cost-effective high voltage MOSFET power operational amplifiers constructed with surface mount components on a thermally conductive but electrically isolated substrate. The metal substrate allows the PA38 and PA39 to dissipate power up to 125 watts and their power supply voltages can range up to +/- 100 Volts (200V total) for the PA38, +/-50 Volts (100V total) for the
PA39 both with a high slew rate of 10 V/µs.
While keeping the cost low, the PA38 and PA39 offer many of the same features and performance specifications found in more expensive hybrid power amplifiers. Without the pre-limitations of hybrid packages the PA38 and PA39 feature external compensation, four-wire current sense, boost voltage, and strapable class cooperation for improved efficiency.
