These current values can be used to determine average power consumption at different one-shot conversion rates. Average power consumption at the automatic
conversion rate of 1.25 kHz is 940 µW.
4
This peak supply current is required for 29 µs (the conversion time plus power-up time) out of every 800 µs (the conversion rate).
5
These current values are derived by not issuing a stop condition at the end of a write or read, thus preventing the part from going into a conversion.
6
The current is derived assuming a 400 kHz serial clock being active continuously.
7
On power-up, the initial input current, I
IN
, on the AS pin is typically 50 µA.
8
The SDA and SCL timing is measured with the input filters turned on so as to meet the fast mode I
2
C specification. Switching off the input filters improves the transfer
rate but has a negative effect on the EMC behavior of the part.

Junction-to-case resistance is applicable to components featuring a
preferential flow direction, such as components mounted on a heat sink.
Junction-to-ambient resistance is more useful for air-cooled, PCB-mounted
components.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
