1 Conversion time is 304 internal clock cycles for both channels (nominal clock 16 kHz); the internal clock frequency is equal to the specified excitation frequency.  
2 Specification is not production tested but is supported by characterization data at initial product release.  
3 Wake-up time is the maximum delay between the last SCL edge writing the configuration register and the start of conversion.  
4 Power-up time is the maximum delay between the VDD crossing the minimum level (1.8 V) and either the start of conversion or when ready to receive a serial  
interface command.  
5 Reset time is the maximum delay between the last SCL edge writing the reset command and either the start of conversion or when ready to receive a serial  
interface command.  
6 Sample tested during initial release to ensure compliance.  
7 All input signals are specified with input rise/fall times = 3 ns, measured between the 10% and 90% points. Timing reference points at 50% for inputs and outputs.  
Output load = 10 pF.
