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.
