A0, A1, A2 – Address Inputs. These input pins specify the address of the device when used in a multi-

dropped configuration. Up to eight individual DS1808s may be addressed on a single 2-wire bus.

H0, H1 – These are the high-end terminals of the potentiometers. For both potentiometers, it is not

required that these terminals be connected to a potential greater than the low-end terminal of the

potentiometer. Voltage applied to the high end of the potentiometers cannot exceed the power supply

L0, L1 – These are the low-end terminals of the potentiometers. It is not required that these terminals be

connected to a potential less than the high-end terminals of the pot. Voltage applied to the low end of the

W0, W1 – Wiper of the Potentiometer. This pin is the wiper terminal of the potentiometer. Voltage
