Notes: 1.

a STOP that initiates a nonvolatile write cycle. It also goes into Standby 9 clock cycles after any START that is not followed by the

correct Slave Address Byte.

2.

is the minimum cycle time to be allowed for any nonvolatile write by the user, unless Acknowledge Polling is used.

3.

For this range of V(VRef) the full scale sink mode current at I1 and I2 follows V(VRef) with a linearity error smaller than 1%.

4.

These parameters are periodically sampled and not 100% tested.

All typical values are for 25°C ambient temperature and 5 V at pin Vcc. Maximum and minimum specifications are
