NOTES:
2. These parameters are periodically sampled and not 100% tested.
3. Parts are 100% tested at +25°C. Over-temperature limits established by characterization and are not production tested.
4. The device goes into Standby: 200ns after any STOP, except those that initiate a nonvolatile write cycle. It goes into Standby tWC after 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.
5. tWC is the time from a valid STOP condition at the end of a write sequence to the end of the self-timed internal nonvolatile write cycle. It is the
minimum cycle time to be allowed for any nonvolatile write by the user, unless Acknowledge Polling is used.
6. 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%.
7. These parameters are periodically sampled and not 100% tested.
8. TCOref = [Max V(VREF) - Min V(VREF)] x 106/(1.21V x +140°C).
Electrical Specifications
Conditions are as follows, unless otherwise specified. All typical values are for TA = +25°C and 5V at pin VCC.
Maximum and minimum specifications are over the recommended operating conditions. All voltages are
referred to the voltage at pin VSS. All bits in control registers are “0”. 255Ω, 0.1%, resistor connected between
R1 and VSS, and another between R2 and VSS. 400kHz TTL input at SCL. SDA pulled to VCC through an
external 2k
Ω resistor. 2-wire interface in “standby” (see Notes 9 and 10 on page 5). WP, A0, A1, and A2 floating.
VREF pin unloaded. (Continued)
