10.1.5 Duty Cycling To Reduce Power Consumption

For applications where power consumption is critical, the TLA202x support duty cycling that yield significant power savings by periodically requesting high data rate readings at an effectively lower data rate. For example, an TLA202x in power-down state with a data rate set to 3300 SPS can be operated by a microcontroller that instructs a single-shot conversion every 7.81 ms (128 SPS). A conversion at 3300 SPS requires approximately 0.3 ms, so the TLA202x enters power-down state for the remaining 7.51 ms. In this configuration, the TLA202x consume approximately 1/25th the power that is otherwise consumed in continuous-conversion mode. The duty cycling rate is arbitrary and is defined by the master controller.
