Maxim Integrated DS1868E-50
- Part Number:
- DS1868E-50
- Manufacturer:
- Maxim Integrated
- Ventron No:
- 3020544-DS1868E-50
- Description:
- IC DGTL POT 50K 2CH 20TSSOP
- Datasheet:
- DS1868E-50
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. The position of the wiper is controlled by a serial interface.
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
20-pin TSSOP, 16-pin SOIC, and 14-pin DIP packages are available
Ultra-low power consumption, quiet, pumpless design
Resistive elements are temperature compensated to ±0.3 LSB relative linearity
2 5V or ±3V operation
Operating Temperature Range: Industrial: -40°C to 85°C
Applications
Volume control
Gain control
Offset adjustment
Current limiting
Voltage regulation
Signal conditioning
