Table 2. Conversion Modes
Conversion Modes Description
Continuous Enabled channels are measured continuously.
Enabled channels are measured, then the device is automatically placed into shutdown mode. This
Low Power cycle is repeated every 728 ms.
When One-Shot Register (address 09h) is programmed while the device is in shutdown or deep
shutdown mode, the device will initiate a single conversion and comparison cycle, after which the
One-Shot device returns to the respective mode it was in.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
