With ample breadboarding areas it is flexible enough to analyze a multitude of standard or proprietary circuit configurations. Critical con - nections for power supply bypassing, compensation and current limiting are pre-wired. Components not usually readily available in engineering labs are provided. External connection to the evaluation kit can be made via the terminals at the edge of the circuit board. These terminal pads are suitable for standard banana jacks or direct soldering of wires. The schematic is shown in Figure 1. PARTS LIST Part # Description, Vendor Quantity CLAMP02 Mounting clip, Apex 1 HS21 Heat sink, Apex 1 EVAL18 PC Board, Apex 1 TWO9 Thermal washer, Apex 1 Box/10 each OX7R105KWN Capacitor, Novacap 2 1825B105K201N CRS01 Resistor, Caddock 2 MP725-0.10-1% CRS02 Resistor, Caddock 2 MP725-0.05-1% ASSEMBLY See Figure 3. 1. Solder the surface mount ceramic capacitors to the DUT side of the circuit board at CVs and CVcc. 2. Select a current limiting resistor from the two values provided. See the product data sheet for information on how to select a value. Apply a thin coating of thermal grease to the back of the resistors. Press the resistor body onto the circuit board foil at positions Ra and Rb and solder the leads. 3. Assemble the amplifier, thermal washer and heat sink to the circuit board as illustrated in Figure 1. As a last step push the clip through the heat sink and circuit board until it locks. Solder the amplifier pins to the circuit side of the circuit board. 4. The four holes at the corners of the circuit board are for mounting #6 standoff spacers if desired. 5. Add other components as necessary to complete your ap - plication circuit. BEFORE YOU GET STARTED * All Apex amplifiers should be handled using proper ESD precautions. * Always use thermal grease between the amplifier and heat - sink. * Always use adequate power supply bypassing. * Do not change connections while the circuit is powered. * Initially set all power supplies to the minimum operating levels allowed in the device data sheet.
