Power supply current (average)
Conversion rate = 0.25/sec
Conversion rate = 2/sec
Power supply current (standby)
SMBus inactive
Conversion time

Remote sensor source current
HIGH level
LOW level
Address pin bias current
Momentary as the address is being read
(Notes 3 and 4)
NOTES:
1. VDD (rising edge) voltage below which the ADC is disabled.
2. VDD (falling edge) voltage below which the logic is reset.
3. Address is read a power up and at start of conversion for all conversions except the fastest rate.
4. Due to the bias current, any pull-up/down resistors should be ≤ 2kΩ.
