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
