AD5115BCPZ80-RL7

Overview

The AD5115BCPZ80-RL7 is a digital potentiometer featuring an 80 kΩ resistance value between terminals A and B. It operates within a supply voltage range of 2.3 V to 5.5 V, with analog signals referenced from GND to VDD. The device supports a maximum clock frequency of 50 MHz for serial data input. Current handling capabilities vary by resistance; the maximum continuous current is ±1.5 mA for the 80 kΩ variant. The component utilizes a three-wire serial interface comprising Chip Select (CS), Clock (CLK), and Up/Down (U/D) pins to control the wiper position.

Feature Summary

• Digital adjustment of resistance via SPI-compatible serial interface
• Maximum operating clock frequency of 50 MHz
• Supply voltage range of 2.3 V to 5.5 V
• Internal EEPROM for non-volatile storage of wiper settings

Applications

• Programmable gain amplifiers
• Voltage reference trimming
• Variable resistor replacement in portable battery-operated applications

Procurement Notes

Verify the specific resistance value associated with the '80' suffix in the model number against official Analog Devices documentation. Confirm package type and tape-and-reel packaging details directly with authorized distributors or the manufacturer to ensure compatibility with assembly requirements.

Selection Notes

Select this component when a solid-state alternative to mechanical potentiometers is required for precision adjustments. Ensure the application voltage does not exceed 5.5 V and that the load current remains within the ±1.5 mA limit for the 80 kΩ configuration. Verify interface compatibility with the host microcontroller's SPI controller.

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 AD5115 specifically denotes the 80 kΩ version. These devices are designed to replace mechanical potentiometers in systems requiring remote programmability and high reliability.

Replacement Considerations

Direct replacements include other members of the AD511x family, such as the AD5111 or AD5113, provided the resistance value matches the circuit requirements. Ensure pinout compatibility and verify that the replacement device supports the required supply voltage and current specifications.
