The PA98 is a 450V power operational amplifier with a very high 1,000V/µs slew rate targeted at high voltage applications including instrumentation, piezoelectric transducers and electrostatic transducers and deflection. Output voltages can swing up to ±215V on dual supplies, and up to +440V single supply. This MOSFET power amplifier also features a very high 30 kHz of power bandwidth and is designed for output currents up to 200mA. The PA98A is the A grade version that provides enhanced performance in the

400V, 4A Power Amplifier with Low Standby Current, High voltage – 400V (±200V),Low quiescent current – 10mA.

The PA78 is a 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, an

The PA09 is a 5A, 80V power operational amplifier designed to drive a variety of loads from DC through the video frequency range. Excellent input accuracy is achieved with a dual monolithic FET input transistor which is cascoded by two high voltage transistors to provide outstanding common mode characteristics. All internal current and voltage levels are referenced to a zener diode biased on by a current source. As a result, the PA09 exhibits superior DC and AC stability over a wide supply and temperature r
