DS3501：High-Voltage NV I²C Potentiometer with Temperature Sensor and LUT

Provides a VCOM Calibrator Solution for TFT-LCD Panels

The DS3501 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 DS3501 contains an on-chip temperature sensor and associated analog-to-digital converter (ADC). The ADC output addresses a 36-byte NV lookup table (LUT). The LUT output can drive the pot directly or be added to an NV initial-value register (IVR) to drive the pot. This flexible LUT-based architecture allows the DS3501 to provide a temperature-compensated potentiometer output with arbitrary slope.

Key Features 128 Wiper Tap Points Full-Scale Resistance: 10kΩ On-Chip Temperature Sensor and ADC 36-Byte Lookup Table (LUT) I²C-Compatible Serial Interface Address Pins Allow Up to Four DS3501s to Share the Same I²C Bus Digital Operating Voltage: 2.7V to 5.5V Analog Operating Voltage: 4.5V to 15.5V Operating Temperature: -40°C to +100°C Pin and Software Compatible with ISL95311 (Default Mode) 10-Pin µSOP Package
