General Description  
Features  
The MAX5395 single, 256-tap volatile, low-voltage  
linear taper digital potentiometer offers three end-to-  
end resistance values of 10k, 50k, and 100k.  
Potentiometer terminals are independent of supply for  
voltages up to 5.25V with single-supply operation from  
1.7V to 5.5V (charge pump enabled). User-controlled  
shutdown modes allow the H, W, or L terminal to be  
opened with the wiper position set to zero-code, mid-  
code, full-code, or the value contained in the wiper  
register. Ultra-low-quiescent supply current (< 1µA) can  
be achieved for supply voltages between 2.6V and 5.5V  
by disabling the internal charge pump and not allowing  
potentiometer terminals to exceed the supply voltage by  
more than 0.3V. The MAX5395 provides a low 50ppm/°C  
end-to-end temperature coefficient and features an I2C  
serial interface.

The small package size, low operating supply voltage,  
low supply current, and automotive temperature range  
of the MAX5395 make the device uniquely suited for the  
portable consumer market, battery-backup industrial  
applications, and automotive market.  
Applications  
Portable Electronics  
System Calibration  
The MAX5395 is available in a lead-free, 8-pin TDFN  
(2mm x 2mm) package. The device operates over the  
-40°C to +125°C automotive temperature range.
