Hello, please let me ask some questions about DRV8305-Q1.
- How should pins of current shunt amplifier be treated if the amplifier is not used? SPx, SNx and SOx pins (x = either of 1, 2 or 3)
- Only the maximum of 60 pF is recommended on the output of the current shunt amplifier, but what if an external resistor is inserted between them to form a RC LPF? The resistance value is not decided yet.
- Can AVDD output be used to drive an external load of about 2 to 3 mA?
- Does Figure 18 on page 45 of the data sheet surely cover all the things users must take care of? Is something else missing?
- For example, in the figure, WAKE pin is left open, but does it in fact have to be tied to somewhere?
Best regards,
