AD5160BRJ50-R2

Overview

The AD5160BRJ5-R2 is a single-channel, 8-bit SPI-compatible digital potentiometer with a nominal end-to-end resistance of 5 kΩ. It provides 256 tap positions for precise resistance adjustment within an 8-lead SOT-23 package. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V and consumes a typical supply current of 8 μA. Key electrical characteristics include a temperature coefficient of 45 ppm/°C, a wiper resistance of 50 Ω to 120 Ω, and a –3 dB bandwidth of 1.2 MHz at midscale. It features volatile memory and powers up to a midscale preset.

Feature Summary

• 256-position resolution with linear taper in a compact SOT-23-8 package
• SPI-compatible 3-wire serial interface (CS, SDI, CLK)
• Single supply operation from 2.7 V to 5.5 V with low power consumption (8 μA typ.)
• Power-on preset to midscale position for safe initialization

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 '-R2' corresponds to the required reel packaging quantity as defined in the manufacturer's ordering guide. Confirm RoHS compliance status via the official datasheet documentation before procurement. Ensure the selected variant matches the required 5 kΩ resistance value and industrial temperature range specifications.

Selection Notes

Select this component when a single-channel digital potentiometer with 5 kΩ nominal resistance is required. The 8-bit resolution offers 256 discrete steps. Consider the 50 Ω to 120 Ω wiper resistance for circuit calculations. Verify that the system supports SPI communication protocols and that the 2.7 V to 5.5 V supply range aligns with the application's power constraints.

Part Context

This part belongs to the AD5160 family of 256-position SPI-compatible digital potentiometers. Other variants in the series offer different nominal resistances, including 10 kΩ, 50 kΩ, and 100 kΩ options. These devices share identical pinouts, interfaces, and functional characteristics, differing primarily in their end-to-end resistance values and associated thermal or current handling limits.

Replacement Considerations

Direct pin-compatible substitutes within the same family include AD5160BRJZ10-R2 (10 kΩ), AD5160BRJZ50-R2 (50 kΩ), and AD5160BRJZ100-R2 (100 kΩ). Selection depends on matching the required nominal resistance value while maintaining the same SOT-23-8 package and SPI interface compatibility.
