Description
General part information
DS3902 Series
The DS3902 features a dual, nonvolatile (NV), low temperature-coefficient, variable digital resistor with 256 user-selectable positions. The DS3902 can operate over a wide supply range of 2.4V to 5.5V, and communication with the device is achieved through an I²C compatible serial interface. Internal address settings allow the DS3902 slave address to be programmed to one of 128 possible addresses. The low cost and the small size of the DS3902 make it an ideal replacement for conventional mechanical-trimming resistors.ApplicationsAudio Power-Amp BiasingInstrumentation and Industrial ControlsOptical TransceiversOptical TranspondersReplacement for Mechanical Variable Resistors and Dip SwitchesRF Power Amps
