... MAXIMUM POWER DISSIPATION Rating The maximum power that can be safely dissipated by the 12.6 V AD8031/AD8032 is limited by the associated rise in junction temperature. The maximum safe junction temperature for 1.3 W plastic encapsulated devices is determined by the glass 0.8 W transition temperature of the plastic, approximately 150°C. ...

... THEORY OF OPERATION The AD8031/AD8032 are single and dual versions of high speed, low power, voltage feedback amplifiers featuring an innovative architecture that maximizes the dynamic range capability on the inputs and outputs. The linear input common- mode range exceeds either supply voltage by 200 mV, and the amplifiers show no phase reversal up to 500 mV beyond supply ...

... The distortion performance of the AD8031/AD8032 amplifiers differs from conventional amplifiers. Typically, the distortion I2 performance of the amplifier degrades as the output voltage 25µA Q47 amplitude increases. Used as a unity gain follower, the output of the AD8031/ C9 Q68 5pF AD8032 exhibits more distortion in the peak output voltage region around V Q27 ...

... A given value of capacitance causes much less ringing when the amplifier is used with a higher noise gain. The capacitive load drive of the AD8031/AD8032 can be increased by adding a low valued resistor in series with the capacitive load. Introducing a series resistor tends to isolate the capacitive load from the feedback loop, thereby diminishing its influence ...
Page 16
... The emitter follower, which is inside the feedback loop, ensures that the output voltage from the AD8031 stays about 700 mV above ground. Using this circuit, low distortion is attainable even when the output signal swings to within ground. ...
