ams OSRAM - TMF8806 Power Calculator

Operating Settings

The TMF8806 is completely switched off between measurements (EN=0) and has a very fast startup time (EN=1). The average VDD current is calculated per measurement cycle. Power of the host is excluded.
This does not result in fastest measurement rate but reduces average power consumption. For fastest operation disable ultra low power mode.

Device is switched off (EN=0) between measurements. Unchecked = device stays in wait (5 MHz OSC) between measurements, no start and config phases. Include power-down current while off
Adds I_VDD power-down (EN=0) for the off time. Unchecked = device is treated as fully off (0 µA).
