Microchip Technology MCP4662T-103E/MF

Description
The MCP45XX and MCP46XX devices are a family of I²C interface digital potentiometers with non-volatile memory. They offer a wide range of product offerings, including:
Single or dual resistor network options
Potentiometer or rheostat configuration options
7-bit or 8-bit resistor network resolution
RAB resistances of 5kΩ, 10kΩ, 50kΩ, or 100kΩ
Zero-scale to full-scale wiper operation
Low wiper resistance (75Ω typical)
Low tempco (50 ppm typical for rheostat, 15 ppm typical for potentiometer)
Non-volatile memory for automatic recall of saved wiper setting
WiperLock™ technology for securing calibration settings
10 general purpose memory locations
I²C serial interface with support for 100 kHz, 400 kHz, and 3.4 MHz
Resistor network terminal disconnect feature
Write protect feature (hardware and software)
Brown-out reset protection (1.5V typical)
Serial interface inactive current (2.5 µA typical)
High-voltage tolerant digital inputs (up to 12.5V)
Wide operating voltage (-2.7V to 5.5V)
Device characteristics specified for 1.8V to 5.5V operation
