1 Accuracy specifications apply only to voltages listed under Test Conditions. See Temperature Accuracy vs. Supply section for typical accuracy performance over the

full VDD supply range.

2 100% production tested at 40°C to these limits.

3 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, IIN, 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 I2C specification. Switching off the input filters improves the transfer

rate but has a negative effect on the EMC behavior of the part.

9 Guaranteed by design. Not tested in production.
