DS1868 Product details

Description

L0, L1 H0, H1 W0, W1 SOUT - Low End of Resistor - High End of Resistor - Wiper Terminal of Resistor - Stacked Configuration Output RST - Serial Port Reset Input DQ - Serial Port Data Input CLK - Serial Port Clock Input COUT - Cascade Port Output VCC - +5 Volt Supply GND - Ground Connections NC - No Internal Connection VB - Substrate Bias Voltage DNC - Do Not Connect All GND pins must be connected to ground.

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.
