������������������������������������������� ���� �������������������������������������������������������������� � � � � � � � � � � � � � � � INTRODUCTION TYPICAL COMPONENT FUNCTIONS Fast, easy breadboarding of circuits using the PA75CX or PA35CX are possible with the EK33 PC board. Mounting holes are provided and the provision for standard banana jacks simplifies connection and testing. Components are labeled on both sides of the board for ease in probing. This kit is not suitable for PA75CC, PA75CD, PA35CC or PA35CD. A multitude of circuit configurations are possible, so only several component locations have specific functions and will usually be necessary: COMPONENT C1, C5, C7, C9 C2, C6 PARTS LIST J3, J9 J2, J8 J4, J6 J5, J10 Part # Eval33 Clamp04 MS11 TW14 Description Evaluation Board Clamp for HS29 Pin Receptacle, 30 pin strip Thermal Washer TO-220 10/Pack Heat Sink, 2.7 DEG/W HS29 Quantity 1 2 1 1 1 R11, R5 FUNCTION Power Supply bypasses MUST be used for each amplifier. Usually ceramic types of .01µF to 1.0µF and 10µF of capacitance per ampere of output current. Feedback resistors The following locations should be jumpered unless used otherwise (their most common function is listed). Output amp a to input amp b -Vs Connects paralleling output a to output b Connects feedback for amp a The following locations should be left open unless used otherwise (their most common anticipated function is listed). J1, J7 Connects -Vs to ground reference The function of all other components is up to the designer's circuit needs.
