Quick Start Procedure

Caution: Do not turn on the power supply until all connections are completed.
• Connect the power supply to V
• Connect one signal generator output to G1IN and GND, another to G2IN and GND. G1 and G2 can be tested altogether
or separately.
• Turn on the power supply and adjust it to 10V.
• Adjust the signal generator to a pulse waveform of 50% duty cycle, 0-5V, 200kHz, turn on the signal generator.
• Connect the probes of an oscilloscope to G1/G2 and GND, G1IN/G2IN and GND for waveforms measurement.
• Verify the G1/G2 amplitude is 9.6V and follow the G1IN/G2IN inputs duty cycle and frequency. Adjust the
frequency/duty cycle of G1IN/G2IN, expect the corresponding change of G1/G2.
Test with Default Load Capacitor
The board has a default set up to test the driver LTC7067 with load capacitors C5 and C6. The typical value of these
capacitors are 3.3nF. Typical waveforms of rising/falling time, propagation delays are below.
