AD5113BCPZ5-RL7

Overview

The AD5113BCPZ5-RL7 is a digital potentiometer from the AD5111/AD5113/AD5115 family, featuring an 8-bit resolution and a single resistive divider (RDAC). It operates with a supply voltage (VDD) ranging from 2.3 V to 5.5 V. The device utilizes a serial interface compatible with SPI standards, utilizing CLK, CS, and U/D pins for data transmission. It includes an internal EEPROM for non-volatile storage of the wiper position. The component supports maximum clock speeds of 50 MHz and handles continuous currents up to ±6 mA for lower resistance variants.

Feature Summary

• 8-bit resolution digital potentiometer with single RDAC channel
• Serial interface supporting SPI-compatible communication protocols
• Internal EEPROM for persistent wiper position storage
• Supply voltage range of 2.3 V to 5.5 V

Applications

• Volume control in audio equipment
• Gain adjustment in instrumentation circuits
• System calibration and offset trimming

Procurement Notes

Verify the specific resistance value associated with the BC suffix against the manufacturer's official datasheet, as the provided quick start guide covers the general family without specifying individual part resistance tolerances or values. Confirm package type CPZ corresponds to the required footprint.

Selection Notes

Select this component when an 8-bit adjustable resistor is required within a 2.3 V to 5.5 V operating range. Ensure the system interface supports the required SPI timing parameters, specifically the 50 MHz maximum clock speed. Verify that the current requirements do not exceed the ±6 mA limit for the specific resistance variant selected.

Part Context

This part belongs to the AD511x series of digital potentiometers manufactured by Analog Devices Inc. The series shares common functional blocks including the power-on reset, up/down control logic, and EEPROM interface. The AD5113 specifically denotes the 8-bit resolution variant within this family.

Replacement Considerations

Check for direct pin-to-pin replacements within the AD5111/AD5113/AD5115 family that match the required resistance value and tolerance. Verify compatibility with existing SPI firmware if replacing with a different bit-resolution variant.
