MAX5395

Single, 256-Tap Volatile, I C, Low-Voltage Linear

Taper Digital Potentiometer

General Description

Features

The MAX5395 single, 256-tap volatile, low-voltage

linear taper digital potentiometer offers three end-to-

end resistance values of 10kΩ, 50kΩ, and 100kΩ.

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

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.
