The X9429WV14-2.7 is a high performance digital potentiometer from the Data Acquisition - Digital Potentiometers range. It is a three-terminal device that combines a voltage-controlled switch and resistive element with a one-slope R-2R resistor ladder circuit in one package to provide an adjustable resistance range. The X9429WV14-2.7 is designed to operate with a low voltage supply and is ideal for applications requiring precision control of an adjustable voltage.

The X9429WV14-2.7 offers a wide range of benefits and features. These include a low on-resistance of 0.05 Ohm, a wide single voltage range of 2.7 V, a maximum resistance range of 20 kOhms, and an output and wiper positions that remain stable during switching transients. This device is also capable of sinking and sourcing up to 10 mA of current, and features low power consumption of 1.1 mW for entire device and 20 mW for adjustable resistor range.

The X9429WV14-2.7 is ideal for use in applications such as level shifting interfaces, LED control, and DACs. It is also suitable for matching the reference voltage ranges of various ICs and enhancing the application’s performance. In addition, the X9429WV14-2.7 can be used as a voltage-controlled resistor in voltage division and transfer functions.

The working principle of the X9429WV14-2.7 involves the use of a one-slope R-2R resistor ladder to adjust the adjustable voltage. When power is applied, the voltage applied to the adjust pin controls the voltage of the output pin. This adjustment can be achieved by selecting the appropriate resistance values which are stored in the device. Once the resistance is selected and set, the output and wiper positions remain constant during the subsequent transient.

The X9429WV14-2.7 also offers protection against shorts and over-currents, as well as a power-off leakage current protection for increased safety. It is also available as an AEC-Q100 compliant device for automotive applications. The X9429WV14-2.7’s wide range of features make it an ideal choice for a variety of applications.
