AD5113BCPZ5-500R7

Overview

The AD5113BCPZ5-500R7 is a digital potentiometer from the AD5111/AD5113/AD5115 family, featuring a 50 kΩ resistance value. It operates with a supply voltage (VDD) ranging from 2.3 V to 5.5 V and supports analog signals between GND and VDD on terminals A, W, and B. The device utilizes a serial interface with a maximum clock speed of 50 MHz for data input. It includes an internal EEPROM for non-volatile storage of wiper settings and offers programmable increment/decrement commands alongside a shutdown mode.

Feature Summary

• 50 kΩ single-channel digital potentiometer
• Serial interface supporting up to 50 MHz clock frequency
• Internal EEPROM for persistent wiper position storage
• Operates within a 2.3 V to 5.5 V power supply range

Applications

• Programmable gain amplifiers
• Voltage reference adjustment
• Digital volume control in audio systems

Procurement Notes

Verify that the specific suffix '500R7' corresponds to the 50 kΩ resistance variant as indicated by the model number structure. Confirm package type matches the CPZ designation found in official Analog Devices documentation. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS circuitry described in the quick start guide.

Selection Notes

Select this component when a 50 kΩ resistance range is required for digital adjustment applications. The AD5113 variant is suitable for systems needing non-volatile memory retention via its internal EEPROM. Ensure the system logic levels are compatible with the SPI-like serial interface operating at up to 50 MHz. Verify that the current requirements do not exceed the ±6 mA limit specified for the 5 kΩ and 10 kΩ versions, noting that the 80 kΩ version has a lower limit.

Part Context

This part belongs to the AD5111/AD5113/AD5115 series of digital potentiometers. The AD5113 specifically denotes the 50 kΩ resistance option within this family, distinguishing it from the 10 kΩ (AD5111) and 80 kΩ (AD5115) counterparts. All variants share identical pinouts, command sets, and functional block diagrams as detailed in the UG-379 quick start guide.

Replacement Considerations

Direct replacements include the AD5111BCPZ5-100R7 for 10 kΩ applications and the AD5115BCPZ5-800R7 for 80 kΩ applications, provided the resistance value difference is acceptable for the circuit design. Other digital potentiometers from Analog Devices with similar serial interfaces and EEPROM features may be considered if pin compatibility and electrical specifications align.
