7.4 Device Functional Modes

The LOG305 offers two functional modes:

  • Disabled- Power Down
    • In this mode, the complete LOG305 is disabled and consumes only IPD current. To enter this mode, tie Log_En to VEE
  • Normal operating mode
    • In this mode, all blocks of the LOG305 are operational. See Section 5.5 for detailed parameters such as power consumption, acceptable supply, and input and output range.
    • This mode can be entered by floating the Log_En or tying the pin to VCC.
