MDT Exclusive: Power Operational Amplifier
The PA78 is a high-voltage, high-speed precision IC power op amp with performance features not found in any commercially available op amp. The novel input stage design of this amplifier provides extremely high slew rates in pulse applications while maintaining low quiescent current of under 1 mA. The output stages are well protected with user defined current limit although the safe operating area must be observed for reliable protection. Proper heatsinking is required for maintaining maximum reliability. External phase compensation provides the user with great flexibility in trading gain, stability, and bandwidth.
