AD5160BRJZ100-RL7

Overview

The AD5160BRJZ100-RL7 is a single-channel, 8-bit SPI-compatible digital potentiometer with a nominal end-to-end resistance of 100 kΩ. It features 256 tap positions and operates on a single supply voltage ranging from 2.7 V to 5.5 V. The device consumes a typical supply current of 3 µA and maintains a low temperature coefficient of 45 ppm/°C. Designed for compact applications, it is housed in an 8-lead SOT-23 package (RJ-8) and supports an operating temperature range from –40°C to +125°C.

Feature Summary

• 256-position adjustment with 8-bit resolution via SPI-compatible interface
• Nominal resistance of 100 kΩ with ±15% tolerance at 25°C
• Low power consumption with 3 µA typical supply current
• Power-on preset to midscale for fault condition recovery

Applications

• Mechanical potentiometer replacement in new designs
• Transducer adjustment for pressure, temperature, position, chemical, and optical sensors
• RF amplifier biasing
• Gain control and offset adjustment

Procurement Notes

Verify the specific suffix 'RL7' indicates reel packaging when sourcing. Confirm RoHS compliance status as indicated by the 'Z' in the base model number. Ensure the 100 kΩ resistance value matches the design requirements, as other variants exist with different resistance values.

Selection Notes

Select this component for applications requiring precise digital control of resistance without mechanical wear. The 100 kΩ value suits high-impedance circuits. Consider the 45 ppm/°C temperature coefficient for thermal stability needs. The SOT-23-8 package is suitable for space-constrained PCB layouts.

Part Context

This part belongs to the AD5160 family of 256-position digital potentiometers. It shares the same interface and pinout with variants offering 5 kΩ, 10 kΩ, and 50 kΩ resistances. The BRJZ designation specifies the commercial temperature grade and SOT-23-8 package type.

Replacement Considerations

Direct replacements include other AD5160 variants with different resistance values if the circuit allows. For dual-channel applications, consider the AD5162. Verify that the SPI timing parameters are compatible with the host microcontroller.
