Product Summary
The DS3902U-530+ is a Dual, NV, Variable Resistor with User EEPROM. It 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. The low cost and the small size of the DS3902U-530+ make it an ideal replacement for conventional mechanical-trimming resistors. The applications of the DS3902U-530+ are Optical Transceivers, Optical Transponders, Instrumentation and Industrial Controls, RF Power Amps, Audio Power-Amp Biasing, Replacement for Mechanical Variable Resistors and DIP Switches.
