Parameter Test Conditions Symbol Limits Units Min Typ Max Potentiometer Resistance ‘−50’ RPOT 50 kW Potentiometer Resistance ‘−00’ RPOT 100 kW Potentiometer Resistance Tolerance 20 % Power Rating 25C 50 mW Wiper Current IW 3 mA Wiper Resistance IW = 3 mA VCC = 3.3 V RW 70 200 W Integral Non-Linearity Voltage Divider Mode INL 1 LSB (Note 4) Differential Non-Linearity DNL 0.5 LSB (Note 4) Integral Non-Linearity Resistor Mode RINL 1 LSB (Note 4) Differential Non-Linearity RDNL 0.5 LSB (Note 4) Voltage on RH or RL VSS = 0 V VTERM VSS VCC V Resolution 0.4 % Zero Scale Error 0 0.5 2 LSB (Note 5) Full Scale Error −2 −0.5 0 LSB (Note 5) Temperature Coefficient of RPOT (Notes 6, 7) TCRPOT 100 ppm/C Ratiometric Temp. Coefficient (Notes 6, 7) TCRATIO 20 ppm/C Potentiometer Capacitances (Notes 6, 7) CH/CL/CW 10/10/25 pF Frequency Response RPOT = 50 kW (Note 8) fc 0.4 MHz 3. Latch-up protection is provided for stresses up to 100 mA on address and data pins from −1 V to VCC +1 V. 4. LSB = RTOT / 255 or (RH − RL) / 255, single pot. 5. V(RW)255−V(RW)0]/255 (RW)255 = 0xFF, (RW)0 = 0x00. 6. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a potentiometer. 7. Relative linearity is a measure of the error in step size. It is determined by the actual change in voltage between two successive tap positions when used as a potentiometer. 8. This parameter is tested initially and after a design or process change that affects the parameter. Table 6. D.C.
