FEATURES  
PIN ASSIGNMENT  
§ Ultra-low power consumption, quiet,  
pumpless design  
§ Two digitally controlled, 256-position  
potentiometers  
§ Serial port provides means for setting and  
reading both potentiometers  
§ Resistors can be connected in series to  
provide increased total resistance  
§ 14-pin DIP, 16-pin SOIC, 20-pin TSSOP  
packages  
§ Resistive elements are temperature  
compensated to ±0.3 LSB relative linearity  
§ Standard resistance values:
