Power
Table 12. Power specifications
Supply current (see Note 5)
+5V EXT output voltage range (see Note 6)
4.5 V minimum, 5.25 V maximum
+5V EXT output current (see Note 7)
Note 5: This is the total current requirement for the USB-1608HS. This specification does not include
any additional contribution due to +5VEXT output current, analog output source current, or DIO
loading.
Note 6: Output voltage range assumes input power supply is within specified limits.
Note 7: This refers to the total amount of current that can be sourced from the +5VEXT terminal pin for
general use.
