Product Summary
The DS3501U+TR is a 7-bit, nonvolatile (NV) digital potentiometer featuring an output voltage range of up to 15.5V. Programming is accomplished by an I2C-compatible interface, which can operate at speeds of up to 400kHz. External voltages are applied at the RL and RH inputs to define the lowest and highest potentiometer outputs. The applications of the DS3501U+TR include TFT-LCD VCOM Calibration, Linear and Nonlinear Compensation, Instrumentation and Industrial Controls, Mechanical POT Replacement, Optical Transceivers.
