AD5262BRU50

Digital Potentiometers Overview

The AD5262BRU50 is a dual-channel, 8-bit digital potentiometer from Analog Devices. It provides two independently programmable variable resistors with 256 tap positions and linear taper. The nominal resistance is 50 kΩ with a temperature coefficient of 35 ppm/°C. It operates on a single supply of 4.5 V to 16.5 V or a dual supply of ±4.5 V to ±5.5 V. The device features a 4-wire SPI-compatible serial interface for data input and output. Key electrical parameters include a wiper resistance of 60 Ω typical, shutdown current of 5 μA, and an operating temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Dual-channel architecture with independent 8-bit control for each channel
• SPI-compatible 4-wire serial interface with daisy-chain capability via SDO pin
• Power-on midscale preset function for safe initialization
• Low power consumption with active shutdown mode reducing current to 5 μA

Digital Potentiometers Applications

• Mechanical potentiometer replacement in industrial systems
• Stereo channel audio level control
• Instrumentation gain and offset adjustment
• Programmable voltage-to-current conversion circuits

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm resistance value and package type. Ensure compatibility with system voltage requirements, as the device supports up to 16.5 V single supply. Check for RoHS compliance status relevant to the manufacturing date code. Confirm availability through authorized distributors as stock levels fluctuate.

Digital Potentiometers Selection Notes

Select this component when dual-channel digital adjustment is required within a 50 kΩ range. The 8-bit resolution offers 256 positions suitable for precision applications. Ensure the host microcontroller supports the required SPI timing parameters, specifically clock frequency and setup/hold times. Consider the TSSOP-16 package dimensions for PCB layout constraints.

Digital Potentiometers Part Context

This part belongs to the AD5260/AD5262 family of 15 V digital potentiometers. The AD5262 variant specifically integrates two channels, whereas the AD5260 provides a single channel. Both share identical electrical characteristics and interface protocols, differing primarily in channel count and pin configuration.

Digital Potentiometers Replacement Considerations

Direct substitutes include other parts from the AD526x family such as the AD5262BRUZ20 (20 kΩ) or AD5262BRU200 (200 kΩ). Verify that any replacement maintains the same 50 kΩ resistance value and TSSOP-16 package footprint.
