Replacement verdict
Compatible functional replacement candidate
The AD5252BRUZ1 and AD5254BRUZ50 share the same dual-channel digital potentiometer architecture, I2C interface, TSSOP-14 footprint, and 256-position resolution, making the AD5254BRUZ50 a viable functional replacement candidate for the AD5252BRUZ1 in applications where the higher 50 kΩ end-to-end resistance is acceptable. Designers must validate the resistance value against circuit requirements, since the tenfold increase from 1 kΩ to 50 kΩ directly affects wiper current, voltage divider ratios, and signal attenuation behavior.

Key electrical and mechanical differences between the two devices
| Parameter | AD5252BRUZ1 | AD5254BRUZ50 | Why it matters |
|---|---|---|---|
| Number of Positions | 256 | 256 | Both are 8-bit (256-position) digital potentiometers, so wiper resolution is identical. |
| Number of Channels | 2 | 4 | Channel count determines how many independent resistance elements are available in the design. |
| End-to-End Resistance | 1 kΩ | 50 kΩ | The nominal resistance directly sets the adjustable resistance range and affects circuit impedance matching. |
| Interface Type | I²C | I²C | Both use a 2-wire I²C-compatible serial interface, allowing similar digital control schemes. |
| Nonvolatile Memory | Yes (EEPROM) | Yes (EEPROM) | On-chip EEPROM retains the wiper setting across power cycles without external storage. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Compatible supply range means both can operate from common 3 V or 5 V logic rails. |
| Resistance Tolerance | ±30% | ±30% | Tolerance indicates the worst-case deviation of end-to-end resistance from its nominal value. |
| Package / Mounting | 14-Lead TSSOP | 20-Lead TSSOP | Different pin counts and package sizes affect PCB footprint and layout compatibility. |
| Operating Temperature Range | -40°C to +105°C | -40°C to +105°C | Identical industrial temperature range supports use in similar environmental conditions. |

Frequently asked questions
What are the key differences between the AD5252BRUZ1 and AD5254BRUZ50?
The AD5252BRUZ1 is a dual-channel, 1 kΩ digital potentiometer, while the AD5254BRUZ50 is a quad-channel, 50 kΩ digital potentiometer. The AD5252 offers two independently programmable resistance channels, whereas the AD5254 provides four channels. Both are single-supply or dual-supply I²C-compatible devices from Analog Devices in 14-lead TSSOP packages.
Are the AD5252BRUZ1 and AD5254BRUZ50 pin-compatible?
No. The AD5252BRUZ1 is a dual-channel device in a 14-lead TSSOP, while the AD5254BRUZ50 is a quad-channel device also in a 14-lead TSSOP but with different pin assignments to accommodate four resistor terminals. They are not direct drop-in replacements for each other.
What is the end-to-end resistance of each device?
The AD5252BRUZ1 has a 1 kΩ nominal end-to-end resistance. The AD5254BRUZ50 has a 50 kΩ nominal end-to-end resistance. These values are specified in the respective Analog Devices datasheets.
How many resistor channels does each part provide?
The AD5252BRUZ1 provides two independent digitally controlled resistor channels. The AD5254BRUZ50 provides four independent digitally controlled resistor channels.
What is the resolution of the AD5252BRUZ1 and AD5254BRUZ50?
Both devices offer 256-position resolution (8-bit) for each resistor channel, as specified in the Analog Devices datasheets.
What communication interface do these digital potentiometers use?
Both the AD5252BRUZ1 and AD5254BRUZ50 use a 2-wire I²C-compatible serial interface for programming and control.
What are the operating supply voltage ranges for these devices?
Both the AD5252BRUZ1 and AD5254BRUZ50 operate from a single supply of 2.7 V to 5.5 V, or from dual supplies of ±2.25 V to ±2.75 V, per the Analog Devices datasheets.
Can the AD5252BRUZ1 be used as a direct substitute for the AD5254BRUZ50 in an existing design?
No. The AD5252BRUZ1 has two channels and 1 kΩ resistance, while the AD5254BRUZ50 has four channels and 50 kΩ resistance. Channel count, resistance value, and pinout differ, so a direct substitution is not possible without redesign and validation.
