AS1500

Applications

The digital potentiometer can replace in many applications the analog trimming potentiometer. The digital

potentiometer is not sensitive to vibrations and shocks. It has an extremely small form-factor and can be adjusted very

fast (e.g. AS1500 has an update rate of 600kHz). Furthermore the temperature drift, resolution and noise are

significant better and cannot be achieved with a mechanical trimming potentiometer. Due to the programmability the

resistor settings can be stored in the system memory, so that after a power down the exact settings can be recalled

easily.

used directly. In the case of a low impedance load, a buffer shall be used.
