Note 1: All voltages are referenced to ground. Currents entering the IC are specified positive and currents exiting the IC are negative.
Note 2: ISTBY is specified with SDA = SCL = VCC and resistor pins floating.
Note 3: ICC is specified with the following conditions: SCL = 400kHz, SDA pulled up, and RL, RW, RH, and Y floating.
Note 4: This is the minimum VCC voltage that causes NV memory to be recalled.
Note 5: This is the time from VCC > VPOR until initial memory recall is complete.
Note 6: 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 7: 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 8: ZSERROR = code 0 wiper voltage divided by one LSB (ideal).
Note 9: FSERROR = (code 127 wiper voltage - V+) divided by one LSB (ideal).
Note 10: I2C interface timing shown is for fast-mode (400kHz) operation. This device is also backward-compatible with I2C stan-
dard mode timing.
Note 11: CB—total capacitance of one bus line in picofarads.
Note 12: EEPROM write time begins after a STOP condition occurs.
Note 13: Pulses narrower than max are suppressed.
(TA = +25°C, unless otherwise noted.)
