Line Impedance Matching GENERAL DESCRIPTION The AD5222 provides a dual channel, 128-position, digitally
controlled variable-resistor (VR) device. This device performs
the same electronic adjustment function as a potentiometer or
variable resistor. These products 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 …
