Description

The PA04 is a high voltage MOSFET power operational amplifier that extends the performance limits of power amplifiers in slew rate and power bandwidth, while maintaining high current and power dissipation ratings.

The PA04 is a highly flexible amplifier. The sleep mode feature of PA04 allows ultra-low quiescent current for standby operation or load protection by disabling the entire amplifier. Boost voltage inputs allow the small signal portion of the amplifier to operate at a higher voltage than the high current output stage. PA04  is then biased to achieve close linear swings to the supply rails at high currents for extra efficient operation. External compensation tailors performance to user needs. A four wire sense technique of PA04 allows precision current limiting without the need to consider internal or external milliohm parasitic resistance in the output line.

The JEDEC MO-127 12-pin Power Dip? package (see Package Outlines) is hermetically sealed and isolated from the internal circuits. The use of compressible thermal washers will void product warranty.

The PA04A is the A grade version.

Applications:

• Sonar Transducer Driver
• Linear and Rotary Motor Drives
• Yoke/Magnetic Field Excitation
• Programmable Power Supplies to ±95V
• Audio up to 400W

The PA04 is designed as one kind of high voltage MOSFET power operational amplifier that extends the performance limits of power amplifiers in slew rate and power bandwidth, while maintaining high current and power dissipation ratings.And the amplifier is then biased to achieve close linear swings to the supply rails at high currents for extra efficient operation.Package of it is hermetically sealed and isolated from the internal circuits.

Features of the PA04 are:(1)high internal dissipation:200 watts;(2)high voltage,high current:200V,20A;(3)high slew rate:50V/uS;(4)4 wire current limit sensing;(5)low distortion;(6)external sleep mode control;(7)optional boost voltage inputs;(8)evaluation kit:see EK04.

The absolute maximum ratings of the PA04 can be summarized as:(1)supply voltage:200 V;(2)boost voltage:supply voltage +20V;(3)output current,within SOA:20 A;(4)power dissipation,internal:200 W;(5)input voltage,differential:+/-20 V;(6)input voltage,common mode:+/-Vs;(7)temperature,pin solder-10 s:300;(8)temperature,junction:150;(9)temperature,storage:-65 to +150;(10)operating temperature range,case:-55 to +125.If you want to know more information such as the electrical characteristics about the PA04,please download the datasheet in www.seekic.com or www.chinaicmart.com .
