Features

Ultra-lowpower consumption, quiet, pumpless design.
Two digitally controlled, 256-position potentiometers.
Serial port provides means for setting and reading both potentiometers.
Resistors can be connected in series to provide increased total resistance.
20-pin TSSOP, 16-pin SOIC, and 14-pin DIP packages are available.
Resistive elements are temperature compensated to ±0.3 LSB relative linearity.
Standard resistance values: - DS1868-10 ∼ 10 kΩ - DS1868-50 ∼ 5.
