General Description
The DS3502 is a 7-bit, nonvolatile (NV) digital poten-
tiometer (POT) featuring an output voltage range of up to
15.5V. Programming is accomplished by an I2C-compat-
ible 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.
Applications
TFT-LCD VCOM Calibration
Instrumentation and Industrial Controls
Mechanical POT Replacement
Features
