I was testing the ADTR1107 on the transmit side, and I observed that the datasheet specifies the control supply currents—such as IDD_SW and ISS_SW—to be in the microamp range. However, the datasheet does not state the absolute maximum current ratings for these supply pins. My concern is that the power supply I am using has a minimum current output capability of 1 mA, which is significantly higher than the typical current these pins draw. I would appreciate clarification on whether it is safe to use such a power supply and whether external load resistors or current sinks are required to ensure proper voltage regulation and stable operation.
Additionally, in the event that the device is not functioning correctly despite aiming for microamp-level currents, is it permissible to supply a slightly higher current—such as in the milliamp range—for testing purposes? If so, how much current (in milliamps) is considered safe for these control supply pins without risking damage to the device?
Thank you for your support and guidance.
