The PA79 is a dual 350V power operational amplifier with a novel input stage that provides extremely high slew rates in pulse applications while maintaining low quiescent current of under 2.5mA. This novel input stage also has the effect of adding variables to the power response and slew rate characteristics of the amplifier.
The output stages for this amplifier are well protected with user defined current limit. External phase compensation provides the user with great flexibility in trading gain, stability and bandwidth. Target applications for the PA79 include piezoelectric positioning, actuation and electrostatic deflection.
This dual amplifier hybrid product is housed in an electrically isolated 20-pin PSOP package that requires less than one square inch of board space, thus providing a cost effective, high density solution for applications where multiple amplifiers are required. A heatsink is required to realize the SOA.
The PA78 provides a single amplifier option.
