FEATURES

Single element 256-position linear taper

potentiometer

Supports potentiometer terminal working

voltages up to 11V

Potentiometer terminal voltage independent

of supply voltage

Potentiometer wiper position controlled and

read over minimal 1-Wire bus interface

100 k

Ω resistor element value

Provides 1-Wire and VDD power modes

Supports Conditional Search based on

power-on default wiper position

Multiple DS2890’s can be identified on a

common 1-Wire bus and operated

independently

Unique factory lasered 64-bit registration

number assures error free device selection

and absolute part identity

Built-in multi-drop controller ensures

compatibility with other 1-Wire Network

products

Supports Overdrive mode which boosts

communication speed up to 142 kbits per

second

-40

oC to +85oC operating temperature range

2.8V – 6.0V operating voltage range
