PIN ASSIGNMENT
DESCRIPTION
The DS1806 Digital Sextet Potentiometer is a six-channel, digitally controlled, solid-state linear
potentiometer. Each potentiometer is comprised of 63 equiresistive sections as illustrated in the block
diagram of Figure 1. Each potentiometer has three terminals accessible to the user. These include the high
side terminals, HX, the wiper terminals, WX, and the low-end terminals, L1-3 and L4-6. Potentiometers 1
through 3 share the same low-end terminal L1-3; likewise, potentiometers 4 through 6 share the low-end
terminal L4-6.
Each wiper’s position is selected via an 8-bit register value. Communication and control of the device is
accomplished via a 3-wire serial port interface. This interface in conjunction with a cascade output allows
the value of the device wiper settings to be read.
