MAX5395NATA+T

The MAX5395NATA+T is a single, 256-tap volatile, I2C, low-voltage linear taper digital potentiometer in 8 pin TDFN package. The single, 256-tap volatile, low-voltage linear taper digital potentiometer offers three end to end resistance values of 100kohm. 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, midcode, full-code, or the value contained in the wiper register. Ultra-low-quiescent supply current (<lt/> 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. Suitable for portable consumer market and battery-backup industrial applications.
