(1) Standby current corresponds to the current consumed in the digital, where not the main oscillator is
running which is used for analog sequencing, but only the low-power oscillator. This standby
current is present in Burst mode; whenever the ASIC is counting down to start a new conversion.
(2) Idle current is the current that is drawn by the ASIC in the IDLE mode, where it can only receive new
commands on the communication bus, but all other blocks are disabled. The analog (excluding the
power-on-reset block) is disconnected, only the digital IO part allows clocking of a few vital gates.
5. Timing Specification
The specifications are applicable at 25degC, unless specified otherwise, and for the complete supply voltage
range.
