AD5115BCPZ80-500R7

Overview

The AD5115BCPZ80-500R7 is a digital potentiometer featuring an 80 kΩ resistance value and 256 programmable tap positions. It operates within a supply voltage range of 2.3 V to 5.5 V, with analog terminals (A, W, B) constrained between ground and VDD. The device utilizes a serial interface supporting clock frequencies up to 50 MHz for data transfer. Maximum continuous current ratings are specified at ±1.5 mA for the 80 kΩ variant. Internal logic includes power-on reset and EEPROM storage capabilities for retaining wiper settings.

Feature Summary

• 256-position digital adjustment with 80 kΩ total resistance
• Serial interface compatible with standard protocols via CLK, CS, and U/D pins
• EEPROM memory retains wiper position during power cycles
• Operates on single supply voltage from 2.3 V to 5.5 V

Applications

• Portable battery-operated equipment requiring low power consumption
• Programmable gain amplifier circuits
• Voltage reference adjustment
• Audio volume control applications

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct channels. Confirm package integrity upon receipt, as the device is electrostatic discharge sensitive. Ensure handling procedures comply with ESD protection standards to prevent performance degradation. Cross-reference ordering codes with official datasheets to confirm specific resistance values and suffix designations.

Selection Notes

Select this component when an 80 kΩ resistance range is required with 256 discrete steps. Verify that the application current does not exceed the ±1.5 mA limit for the 80 kΩ configuration. Ensure the system voltage remains within the 2.3 V to 5.5 V operating window. Consider the 50 MHz maximum clock speed for high-speed serial communication requirements.

Part Context

This part belongs to the AD511x family of digital potentiometers, which includes variants with different resistance values such as 5 kΩ and 10 kΩ. The BC suffix typically denotes temperature range specifications, while the 80 indicates the nominal resistance. The CPZ package identifies the specific surface-mount housing used for this component.

Replacement Considerations

Direct replacements include other AD5115 variants with matching 80 kΩ resistance and pinout compatibility. Ensure substitute components support the same 256-position resolution and EEPROM retention features. Verify that alternative packages maintain identical electrical characteristics and thermal performance.
