ANALOG DEVICES AD5222BRZ50 易失性数字电位器, 50 kohm, 双, 递增递减, ± 30%, 2.7 V
The is a dual-channel increment/decrement Digital Potentiometer for use with programmable voltage-to-current conversion. This device performs the same electronic adjustment function as a potentiometer or variable resistor. These conducts were optimized for instrument and test equipment push-button applications. Choices between bandwidth or power dissipation are available as a result of the wide selection of end-to-end terminal resistance values. The AD5222 contains two fixed resistors with wiper contacts that tap the fixed resistor value at a point determined by a digitally controlled up/down counter. The resistance between the wiper and either end point of the fixed resistor provides a constant resistance step size that is equal to the end-to-end resistance divided by the number of positions. The variable resistor offers a true adjustable value of resistance, between Terminal A and the wiper or Terminal B and the wiper.
ESD sensitive device. Electrostatic charges as high as 4000V readily accumulate on the human body and test equipment and can discharge without detection.
