AF Power Amplifier (Split Power Supply) (100 W min, THD = 0.008 %)

SANYO -> Panasonic 

Ordering number : EN4608A

Thick Film Hybrid IC

STK4044XI

AF Power Amplifier (Split Power Supply)

(100 W min, THD = 0.008 %)

Features

• Compact packaging supports slimmer set designs

• Series designed from 50 up to 150 W and pin-

compatibility

• Simpler heat sink design facilitates thermal design of

slim stereo sets

Specifications

Maximum Ratings at Ta = 25°C

• Current mirror circuit, cascade circuit and pure-

complimentary circuit application reduce distortion to

0.008 %

• Supports addition of electronic circuits for thermal

shutdown and load-short protection circuit as well as

pop noise muting which occurs when the power supply

switch is turned on and off.

Note: Use rated power supply for test unless otherwise specified.

*1 When measuring permissible load short time and output noise voltage use transformer power supply indicated next page.

*2 Output noise voltage represents the peak value on the rms scale (VTVM). The noise voltage waveform does not include the pulse noise.

Any and all SANYO products described or contained herein do not have specifications that can handle

applications that require extremely high levels of reliability, such as life-support systems, aircraft’s

control systems, or other applications whose failure can be reasonably expected to result in serious

physical and/or material damage. Consult with your SANYO representative nearest you before using

any SANYO products described or contained herein in such applications.

SANYO assumes no responsibility for equipment failures that result from using products at values that

exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other

parameters) listed in products specifications of any and all SANYO products described or contained

herein.
