The example component configuration shown in the Figure 6-1 illustrates a default board setup for evaluating the THS4567 amplifier. In the configuration shown, the board is set for 50-Ω single ended voltage input on IN- (J1) and output on OUT+ (J8). The gain is set to approximately 7 V/V using the input and feedback resistors, and resistor R2 provides the 50-Ω input impedance match while R12 balances the inpedance on the non-signal input. The output network created by R6, R7, and R16 form a total load of 1kΩ to the amplifier while still providing a 50-Ω output impedance match. In addition to the impedance matching, the output network also attenuates the total output an additional 32 dB.

The input common mode enable and amplifier enable functions are set by default for easy control using jumpers J7 and J5 respectively. The Vocm and Vicm voltage signals are set up for simple DC voltage control using the test points TP1 and TP7.

The power supply is set up for a split supply configuration with three decoupling capacitors on each supply to provide high speed decoupling performance.
