DESCRIPTION

The DS1667 is a dual-solid state potentiometer that is adjustable by digitally selected resistive elements.

Each potentiometer is composed of 256 resistive elements. Between each resistive section of each

potentiometer are tap points accessible to the wiper. The position of the wiper on the resistive array is set

by an 8-bit register that controls which tap point is connected to the wiper output. Each 8-bit register can

be read or written by sending or receiving data bits over a 3-wire serial port. In addition, the resistors can

be stacked such that a single potentiometer of 512 sections results. When two separate potentiometers are

used, the resolution of the DS1667 is equal to the resistance value divided by 256. When the

potentiometers are stacked end to end, the resistance value is doubled while the resolution remains the
