Description
The SA09 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 overloads as well as shorts to supply or ground. The current limit is programmable with one or two external resistors depending on the application. A shutdown input disables all output bridge drivers. The 18 pin steel package is hermetically sealed.
Applications:
- High Fidelity Audio Amplifier
- Brush Type Motor Control
- Vibration Cancelling Amplifier
