HIGH VOLTAGE POWER OPERATIONAL AMPLIFIER UNEDITABLE
The PA89 is an ultra high voltage, MOSFET operational amplifier designed for output currents up to 75 mA. Output voltages can swing over 1000V p-p. The safe operating area (SOA) has no second breakdown limitations and can be observed with all types of loads by choosing an appropriate current limiting resistor. High accuracy is achieved with a cascode input circuit configuration and 120dB open loop gain. All internal biasing is referenced to a bootstrapped zener- MOSFET current source, giving the
Pulse Width Modulation Amplifiers
The SA07 amplifier is a 40 volt, 500kHz PWM amplifier. The full bridge output circuit provides 5 amps of continuous drive current for applications as diverse as high fidelity audio and brush type motors. Clock output and input pins can be used for synchronization with other amplifiers or an externally generated clock. An integrator amplifier is provided. Direct access to the pwm input is provided for connection to digital motion control circuits. Protection circuits guard against thermal overloa
