DESCRIPTION

The amplifier design consists of dual power op amp on a single

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

power audio applications.

The PA75 is available in three standard package designs. The

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).

The monolithic amplifier is directly attached to the metal tabs

of the PA75CC, PA75CD, and PA75CX. The metal tabs of the

packages are directly tied to -Vs.

Combining the power op amp (master channel A) and the

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

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

(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.
