Note 1: All voltages are referenced to ground. Currents entering the IC are specified positive and currents exiting the IC are nega-
tive.
Note 2: ICC is specified with the following conditions: SCL = 400kHz; SDA pulled up; and RL, RW, RH floating.
Note 3: ICC is specified with the following conditions: SCL, SDA pulled up; RL, RW, RH floating; and temperature sensor on.
Note 4: ISTBY is specified with SDA = SCL = VCC = 5.5V, resistor pins floating, and CR2 bit 0 = logic-high.
Note 5: This is the minimum VCC voltage that causes NV memory to be recalled.
Note 6: This is the time from VCC > VPOR until initial memory recall is complete.
Note 7: Guaranteed by design.
Note 8: Integral nonlinearity is the deviation of a measured resistor setting value from the expected values at each particular resis-
tor setting. Expected value is calculated by connecting a straight line from the measured minimum setting to the measured
maximum setting. INL = [V(RW)i - (V(RW)0] / LSB(ideal) - i, for i = 0...127.
Note 9: Differential nonlinearity is the deviation of the step-size change between two LSB settings from the expected step size. The
expected LSB step size is the slope of the straight line from measured minimum position to measured maximum position.
DNL = [V(RW)i+1 - (V(RW)i] / LSB(ideal) - 1, for i = 0...126.
Note 10: ZS error = code 0 wiper voltage divided by one LSB(ideal).
Note 11: FS error = (code 127 wiper voltage - V+) divided by one LSB (ideal).
Note 12: I2C interface timing shown is for fast-mode (400kHz) operation. This device is also backward-compatible with I2C standard
mode timing.
Note 13: CB—total capacitance of one bus line in picofarads.
Note 14: EEPROM write time begins after a STOP condition occurs.
Note 15: Pulses narrower than max are suppressed.
