Overview
The AD5207BRUZ10-RL7 is a dual-channel, 8-bit digital potentiometer with 256 tap positions and a nominal resistance of 10 kΩ. It operates on a single supply from 2.7 V to 5.5 V or dual supplies up to ±2.7 V. The device features a 3-wire SPI-compatible serial interface for data input and includes a power-down mode consuming less than 5 µA. It is housed in a TSSOP-14 package and guaranteed to operate over an extended industrial temperature range of –40°C to +125°C.
Feature Summary
- Dual-channel architecture with 256 programmable positions per channel
- 10 kΩ nominal end-to-end resistance with ±30% tolerance
- 3-Wire SPI-compatible serial control interface with daisy-chain capability via SDO
- Power shutdown mode reduces current consumption to under 5 µA
Applications
- Mechanical potentiometer replacement
- Stereo channel audio level control
- Instrumentation gain and offset adjustment
- Programmable voltage-to-current conversion
- Line impedance matching
Procurement Notes
Verify the specific resistance value suffix (e.g., 10 for 10 kΩ) matches the design requirement. Confirm the 'B' grade indicates the specified industrial temperature range and performance characteristics. Ensure the RL7 packaging format aligns with automated assembly needs.
Selection Notes
Select this component when a dual-channel solution is required within a compact TSSOP-14 footprint. The 10 kΩ value offers a balance between noise performance and drive capability. Verify that the system logic levels are compatible with the 3-wire serial interface requirements.
Part Context
This part belongs to the AD5207 family of 256-position digital potentiometers. The BRUZ10 designation specifies the B-grade temperature range, TSSOP-14 package, and 10 kΩ resistance. The -RL7 suffix indicates tape and reel packaging for high-volume manufacturing.
Replacement Considerations
The AD8402 serves as a drop-in replacement due to compatible address bit structures. Other AD52xx series devices may require interface adjustments if they utilize different control protocols or pinouts.
