... DESCRIPTION The SA07 amplifier volt, 500kHz PWM amplifier. The full bridge output circuit provides 5 amps of con- tinuous 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 ...

... OPERATING TEMPERATURE RANGE, case INPUTS CAUTION The SA07 is constructed from MOSFET transistors. ESD handling procedures must be observed. The internal substrate contains beryllia (BeO). Do not break the seal. If accidentally broken, do not crush, machine, or subject to temperatures in excess of 850°C to avoid generating toxic fumes. ...

... CC NOISE FILTERING Switching noise can enter the SA07 through the INT OUT to +PWM connection. A wise precaution is to low pass filter this connection. Adjust the pass band of the filter to 10 times the bandwidth required by the application. Keep the resistor value to 100 ohms or less since this resistor becomes part of the hysteresis circuit on the pwm com- parator ...

... Noise or flyback may be observed at the outputs during this time due to the high impedance of the outputs in the off state. This will vary with the nature of the load restart the SA07 remove the fault and recycle V down pulse. ...
