AD5112BCPZ5-500R7

AD5112 is a single-channel, 64 position, I²C, resistor tolerance, non-volatile digital potentiometer. The low resistor tolerance, low nominal temperature coefficient and high bandwidth simplify open loop applications, as well as tolerance matching applications. The new low wiper resistance feature minimizes the wiper resistance in the extremes of the resistor array to only 45 ohm, typical. The wiper settings are controllable through an I²C-compatible digital interface that is also used to readback the wiper register and EEPROM content. Resistor tolerance is stored within EEPROM, providing an end-to-end tolerance accuracy of 0.1%. It is widely used in application such as mechanical potentiometer replacement, portable electronics level adjustment, audio volume control, low resolution DAC, LCD panel brightness and contrast control, programmable voltage to current conversion, programmable filters, delays, time constants, feedback resistor programmable power supply, sensor calibration etc.

• Nominal resistor tolerance error is ±8% maximum
• Wiper current is ±6mA, 1million write cycles
• Rheostat mode temperature coefficient is 35ppm/°C typical
• Low power consumption is 2.5µA max at (2.7V and 125°C)
• Wide bandwidth is 4MHz typical, resistance is 5 ohm
• Power-on EEPROM refresh time is 50μs maximum
• 50-year typical data retention at 125°C
• Analog supply operation is 2.3V to 5.5V, logic supply operation is 1.8V to 5.5V
• Operating temperature is -40°C to +125°C
• Package style is 8-lead LFCSP
