DS1267B Dual Digital Potentiometer
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
