AD5160BRJZ10-RL7 is the 10 kohm version of the AD5160 256-position SPI-compatible digital potentiometer. The resistance option is part of the order-code identity: this device provides a nominal 10 kohm end-to-end resistance rather than the 100 kohm value of the otherwise similar BRJZ100 variant. The device operates from 2.7 V to 5.5 V and powers up at midscale. That predictable startup point is useful in digitally adjusted gain, bias, or calibration networks where an uncontrolled endpoint at power-up would be undesirable.

Engineering Selection Notes
- Treat 10 kohm as the exact end-to-end resistance option; it is the primary electrical difference from the 100 kohm order code in this batch.
- The 256 positions set the available wiper codes, but actual resistance at each code also includes wiper resistance and end-to-end tolerance.
- Power-on midscale provides a defined startup code; the host can then program the final value over SPI.
- The SOT-23-8 footprint, -40 to +125 C range and RL7 packing are exact procurement attributes.
Lifecycle and Procurement Context
Manufacturer lifecycle status: Production. This status is included for procurement planning and should be rechecked for long-term BOM decisions.
For the higher-resistance AD5160 ordering option, compare AD5160BRJZ100-RL7 (100 kΩ). It uses the same SPI-compatible family but changes the analog resistance range and loading. See the digital potentiometer category to compare other interfaces.
