AD5160BRJZ5-RL7

Overview

The AD5160BRJZ5-RL7 is a single-channel, 256-position digital potentiometer manufactured by Analog Devices. It features an end-to-end resistance of 5 kΩ with a linear taper and ±20% tolerance at 25°C. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V, consuming a typical supply current of 8 µA. It utilizes an SPI-compatible 3-wire serial interface for control. Key electrical characteristics include a temperature coefficient of 45 ppm/°C, a bandwidth of 1.2 MHz at midscale, and a settling time of 1 µs. The component is housed in a compact SOT-23-8 package and supports an operating temperature range from –40°C to +125°C.

Feature Summary

• 256-position resolution with 8-bit digital control via SPI-compatible interface
• Single supply operation from 2.7 V to 5.5 V with low power consumption (8 µA typical)
• Compact 8-lead SOT-23 package (2.9 mm × 3 mm) suitable for space-constrained designs
• Power-on preset to midscale position for simplified fault 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 circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging type and compliance status. The suffix indicates reel packaging configuration. Ensure compatibility with existing board layouts regarding the SOT-23-8 footprint dimensions and thermal requirements. Cross-reference the part number with the latest datasheet revision to confirm pinout and electrical specifications remain unchanged.

Selection Notes

Select this component when a solid-state replacement for mechanical potentiometers is required in portable or battery-operated applications due to its low supply current. The 5 kΩ resistance value is suitable for moderate impedance circuits. Verify that the system logic levels are compatible with the SPI interface inputs. Consider the 45 ppm/°C temperature coefficient for precision applications requiring stable resistance over wide temperature ranges.

Part Context

The AD5160BRJZ5-RL7 belongs to the AD5160 family of digital potentiometers. This family offers various end-to-end resistance options including 10 kΩ, 50 kΩ, and 100 kΩ. All variants share the same 256-position resolution, SPI interface, and SOT-23-8 package form factor. The 'B' grade indicates the commercial temperature range and tolerance specifications defined in the datasheet.

Replacement Considerations

Direct replacements within the AD5160 series include AD5160BRJZ10-RL7 (10 kΩ), AD5160BRJZ50-RL7 (50 kΩ), and AD5160BRJZ100-RL7 (100 kΩ). These parts maintain identical pinouts and functionality but differ in nominal resistance values. Ensure the selected resistance value matches the circuit design requirements.
