AD5113BCPZ10-RL7

Overview

The AD5113BCPZ10-RL7 is a digital potentiometer from the AD5111/AD5113/AD5115 family, featuring a 10 kΩ resistance value. 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 protocols, utilizing CLK, CS, and U/D pins for data transmission. It includes an internal EEPROM for non-volatile storage of wiper settings. The component supports maximum clock frequencies up to 50 MHz and allows for increment, decrement, shutdown, and store commands via its control logic.

Feature Summary

• 10 kΩ nominal resistance with single-ended operation
• Serial interface supporting 50 MHz maximum clock speed
• Non-volatile memory for persistent wiper position storage
• Operates within a 2.3 V to 5.5 V power supply range

Applications

• Volume control in audio systems
• Gain adjustment in instrumentation amplifiers
• Voltage reference trimming
• Programmable biasing circuits

Procurement Notes

Verify the specific resistance tolerance and temperature coefficient associated with the 'B' grade suffix by consulting the official AD5113 datasheet. Confirm that the CPZ package type matches the required PCB footprint and thermal management needs for the target application environment.

Selection Notes

Select this component when a 10 kΩ digital potentiometer is required with SPI compatibility. Ensure the system voltage falls between 2.3 V and 5.5 V. Consider the current limits: ±6 mA for 5 kΩ/10 kΩ variants. Verify if non-volatile memory retention is necessary for the design, as this model includes EEPROM storage capabilities.

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 RDAC, register, and control logic. The AD5113 specifically denotes the 10 kΩ variant, distinguishing it from the 5 kΩ (AD5111) and 80 kΩ (AD5115) counterparts in terms of current handling and impedance characteristics.

Replacement Considerations

Direct replacements include AD5111BCPZ10-RL7 (5 kΩ) or AD5115BCPZ10-RL7 (80 kΩ) if resistance values differ. For identical 10 kΩ specifications, verify pinout compatibility and electrical ratings against other AD5113 revisions or grades.
