DS1267B - Dual Digital Potentiometer

General Description

L0, L1 - Low End of Resistor H0, H1 - High End of Resistor W0, W1 - Wiper Terminal of Resistor VB SOUT - Substrate Bias Voltage - Stacked Configuration Output RST - Serial Port Reset Input DQ - Serial Port Data Input CLK - Serial Port Clock Input COUT VCC GND - Cascade Port Output - +5V S

Key Features

  • 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 16-pin SO and 20-pin TSSOP packages Resistive elements are temperature compensated to ±0.3 LSB relative linearity Standard resistance values:.
  • DS1267B-10 ~ 10kΩ.
  • DS1267B-50 ~ 50kΩ.
  • DS1267B-100 ~ 100kΩ Operating Temperature Range:.
  • Industrial: -40°C to +85°C PIN A.
