DS1267
Dual Digital Potentiometer Chip
www.dalsemi.com
FEATURES
Ultra-low power 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
14-pin DIP, 16-pin SOIC, 20-pin TSSOP
packages
Resistive elements are temperature
compensated to 卤0.3 LSB relative linearity
Standard resistance values:
鈥?DS1267-10 ~ 10 k鈩?/div>
鈥?DS1267-50 ~ 50 k鈩?/div>
鈥?DS1267-100 ~ 100 k鈩?/div>
Operating Temperature Range:
鈥?Industrial: -40掳C to +85掳C
