Low-Cost VCOM Calibrator with Anti-Image-Stick Features
The DS3503 features two synchronized stepping digital potentiometers: one 7-bit potentiometer with RW as its output, and another potentiometer with Y as its output. Both potentiometers reference the RH and RL terminals and feature an output voltage range of up to 15.5V. In addition, both potentiometer outputs can be stepped up and down by configuring the control registers. Programming is accomplished by an I²C-compatible interface that can operate at speeds of up to 400kHz.
