7.4.3 Standby Mode

The device supports a low-power standby mode in which only part of the circuit is powered down. The analog front-end, signal-conditioning circuit for each channel and the internal reference is powered down in this mode. In standby mode, the total power consumption of the device is typically equal to 6.5mW. To put the device in the low-power standby mode, set the DEVICE_PDN bit field of the PDN_CTL register to 1b.
