To save power, the LDC0851 has a shutdown mode. In order to place the LDC0851 in shutdown mode set the EN (Enable) pin low. This mode is useful for low power applications where the EN pin can be duty cycled at a low rate for wake-up applications to achieve a very low average supply current. An example of a duty-cycled application can be found in the applications section Low Power Operation. To resume active operation, set EN high and wait t_AMT + t_DELAY for valid output data. The current consumption in this mode is given in the electrical table as I_SD. Note that the output will remain high (OFF) when EN is low. See Power-Up Conditions for more information on the startup conditions.
