DS3904U-020+
Digital Potentiometer ICs Triple, 128-Position, Nonvolatile, Variable, Digital Resistor/Switch
Brands: Analog Devices Inc./Maxim Integrated
Mfr.Part #: DS3904U-020+
Datasheet: DS3904U-020+ Datasheet (PDF)
Package/Case: 8-TSSOP,8-MSOP(0.118",3.00mmWidth)
DS3904U-020+ General Description
The DS3904/DS3905 contain three nonvolatile (NV) lowtemperature coefficient, variable digital resistors. Eachresistor has 128 user-selectable positions. Additionally,the DS3904/DS3905 have a high-impedance setting thatallows each resistor to function as a digital switch. TheDS3904/DS3905 can operate over a 2.7V to 5.5V supplyvoltage range, and communication with the device isachieved through a 2-wire serial interface. Address pinsallow multiple DS3904/DS3905s to operate on the sametwo-wire bus. The DS3904 has one address pin, allowingtwo DS3904s to share the bus, while the DS3905has three address pins, allowing up to eight DS3905s toshare a common bus. The low-cost and small size of theDS3904/DS3905 make them ideal replacements for conventionalmechanical trimming resistors.
