ELECTRICAL CHARACTERISTICS (CONTINUED)
All typical values are for 25°C ambient temperature and 5 V at pin Vcc. Maximum and minimum specifications are
over the recommended operating conditions. All voltages are referred to the voltage at pin Vss unless otherwise
specified. All bits in control registers are “0” unless otherwise specified. 510 Ω , 0.1%, resistor connected between R1
and Vss, and another between R2 and Vss unless otherwise specified. 400kHz TTL input at SCL unless otherwise
specified. SDA pulled to Vcc through an external 2k Ω resistor unless otherwise specified. 2-wire interface in “standby”
(see notes 1 and 2 on page 22), unless otherwise specified. WP, A0, A1, and A2 floating unless otherwise specified.
VRef pin unloaded, unless otherwise specified.

See note 4 and 5.
See note 3.
See note 4.
See Figure 8.
Notes: 1. The device goes into Standby: 200 ns after any STOP, except those that initiate a nonvolatile write cycle. It goes into Standby t WC 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 cor-
rect Slave Address Byte.
2. t WC 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.
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.
5. TCO ref = [Max V(V REF ) - Min V(V REF )] x 10 6 /(1.21V x 140°C)
