Overview
The AD5115BCPZ10-500R7 is a digital potentiometer featuring a 500 Ω resistance value with 64 tap positions. It operates within a supply voltage range of 2.3 V to 5.5 V and utilizes an SPI-compatible serial interface for data transfer. The device includes an internal EEPROM for nonvolatile storage of wiper settings, ensuring data retention upon power loss. Maximum continuous current ratings are ±6 mA for the 5 kΩ and 10 kΩ variants, while the clock input supports frequencies up to 50 MHz.
Feature Summary
- 64-position digital potentiometer with 500 Ω nominal resistance
- Nonvolatile EEPROM memory for persistent wiper setting storage
- SPI-compatible serial interface supporting 50 MHz maximum clock frequency
- Operates on a single 2.3 V to 5.5 V power supply
Applications
- Programmable gain amplifiers
- Voltage reference adjustment
- Digital volume control in audio systems
Procurement Notes
Verify the specific suffix 'R7' against official documentation to confirm tape and reel packaging specifications. Ensure that the 500 Ω resistance variant matches the application requirements, as other resistance values may have different current handling capabilities.
Selection Notes
Select this component when a low-resistance digital potentiometer with nonvolatile memory is required. Verify that the system's serial interface timing aligns with the 50 MHz maximum clock speed and that the operating voltage falls within the 2.3 V to 5.5 V range.
Part Context
This part belongs to the AD511x family of digital potentiometers, which includes the AD5111, AD5113, and AD5115. These devices share similar functional block diagrams and command sets but differ in resistance values and resolution. The AD5115 specifically offers 64 tap positions.
Replacement Considerations
Check for direct pin-to-pin replacements within the AD511x series or other Analog Devices digital potentiometers with matching resistance and interface specifications.
FAQ
What is the maximum clock frequency supported by the AD5115?
The maximum clock frequency for the CLK input is 50 MHz.
How many tap positions does the AD5115 provide?
The AD5115 provides 64 tap positions for resistance adjustment.
Is the wiper setting retained after power loss?
Yes, the device features internal EEPROM that stores the wiper setting, retaining it even when power is removed.
