DESCRIPTION
●The DS1868 Dual Digital Potentiometer Chip consists of two digitally controlled solid-state potentiometers. Each potentiometer is composed of 256 resistive sections. Between each resistive section and both ends of the potentiometer are tap points which are accessible to the wiper.
●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 kW
●- DS1868-50 ~ 50 kW
●- DS1868-100 ~ 100 kW
●+5V or ±3V operation
●Operating Temperature Range:
●\- Industrial: -40°C to 85°C
