Hi Team, The customer has some questions about DRV2510-Q1 . We can see "Table 1. Gain Configuration Table" of the datasheet. The input impedance has 20dB/26dB/32dB/36dB in the table 1. Q1: What does the Gain mean in the table 1? Does the Gain mean the voltage gain or the current gain? Q2: What are the relationship between the Gain set and output? Q3: The duty cycle percentage of PWM issue: If the duty cycle of the input PWM signal is greater than 50%, the motor is moving toward outside. If the duty cycle of the input PWM signal is lower than 50%, the motor is moving toward opposite. What is the reason? Can the duty cycle percentage of PWM determine the motion directions of voice coil motor? Q4: The output wave issue: The actual output wave is different to "Figure 5. BD Mode Modulation" of the datasheet. What is the reason? Please check the attachment. The yellow line is the OUT+ wave and the blue line is the OUT- wave. The customer's schematic is also in the attachment. The customer uses the single-ended output. Best Wishes, Mickey Zhang Asia Customer Support Center Texas Instruments
