Dual, 64-Position Nonvolatile Digital  
Potentiometer with Buffered Outputs  
General Description  
Features  
The DS3908 contains two nonvolatile digital poten-  
tiometers with programmable-gain amplifiers buffering  
the wiper outputs. The potentiometer position and  
Two 64-Position Linear Taper Potentiometers  
Integral Wiper Buffering Amplifiers with  
Selectable Gains of 1V/V, 2V/V, or 4V/V  
2
amplifier gain are controlled through an I C-compatible  
100kΩ Potentiometer End-to-End Resistance  
Low Potentiometer Temperature Coefficient  
Nonvolatile Wiper and Gain Storage  
serial bus. The DS3908 operates in both 3.3V and 5V  
systems and features a write-protect pin that locks the  
position of the potentiometers and gain registers. Up to  
2
eight DS3908s can be placed on a single I C bus.
