DESCRIPTION

monolithic die. Side B of the dual monolithic is configured as a

unity gain buffer to increase the current capability of the master

side A. The use of two PA75 amplifiers provides a cost-effective

solution to applications where multiple amplifiers are required or

a bridge configuration is needed. Very low harmonic distortion

of .02% THD and low I

power audio applications.

surface mount version of the PA75, the PA75CC, is an industry

standard non-hermetic plastic 7-pin DDPAK. The through hole

version of the PA75, the PA75CD and PA75CX, are industry

standard non-hermetic plastic 7-pin TO-220 packages. The

PA75CX is staggered lead formed and offers standard 100 mil

spacing. This allows for easier PC board layout. (Please refer to

the CX lead form package drawing for dimension of the PA75CX).

TYPICAL APPLICATION

Ref: APPLICATION NOTES 8, 20, 26

unity gain buffer (slave channel B) in a parallel connection

yields a single 2.5A amplifier. RI and RF can set up channel A

for the required gain for the overall circuit. Small values of R

(sense resistors) are used on the outputs to improve current

sharing characteristics. The master amplifier can be configured

in inverting or non-inverting gain configurations.

... THERMAL CONSIDERATIONS The PA75CD and CX have a large exposed copper heat tab to which the monolithic is directly attached. The PA75CD and CX may require a thermal washer, which is electrically insulating since the tab is directly tied to -VS. This can result in a thermal impedance RCS 1˚C/W or greater. ...
