DS3502 Datasheet | Maxim Integrated

Rev 1; 3/09 High-Voltage, NV, I2C POT General Description The DS3502 is a 7-bit, nonvolatile (NV) digital potentiometer (POT) featuring an output voltage range of up to 15.5V. Programming is acplished by an I2C-patible interface, which can operate at speeds of up to 400k Hz. External voltages are applied at the RL and RH inputs to define the lowest and highest potentiometer outputs. - - - 128 Wiper Tap Points Full-Scale Resistance: 10kΩ I2C-patible Serial Interface Features - Address Pins Allow Up to Four DS3502s to Share the Same I2C Bus - Digital Operating Voltage: 2.5V to 5.5V - Analog Operating Voltage: 4.5V to 15.5V - Operating Temperature: -40°C to +100°C - 10-Pin µSOP Package Applications TFT-LCD V Calibration Instrumentation and Industrial Controls Mechanical POT Replacement Ordering Information PART DS3502U+ TEMP RANGE -40°C to +100°C -40°C to +100°C PIN-PACKAGE 10 μSOP 10 μSOP Pin Configuration and Typical Operating Circuit appear at end of data sheet.
