AD5160BRJZ50-R2

Overview

The AD5160BRJZ50-R2 is a single-channel, 8-bit SPI-compatible digital potentiometer manufactured by Analog Devices. It features a nominal end-to-end resistance of 50 kΩ with 256 tap positions and linear taper. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V, consuming a typical supply current of 3 µA. It provides a low temperature coefficient of 45 ppm/°C for the resistor element and 15 ppm/°C in potentiometer divider mode. The component is housed in an 8-lead SOT-23 package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• 256-position resolution with 8-bit SPI digital interface
• Nominal resistance of 50 kΩ with ±15% tolerance at 25°C
• Single supply operation from 2.7 V to 5.5 V with 3 µA typical current
• Power-on preset to midscale (code 0x80) for 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 '-R2' corresponds to the required tape and reel packaging quantity as defined in the manufacturer's ordering guide. Confirm RoHS compliance status via the official datasheet documentation before integration into production assemblies.

Selection Notes

Select this variant when a 50 kΩ end-to-end resistance is required. Ensure the system design accommodates the 2.9 mm × 3 mm SOT-23-8 footprint. Verify that the SPI clock frequency does not exceed 25 MHz and that logic levels are compatible with the 2.7 V to 5.5 V supply range.

Part Context

This component belongs to the AD5160 family of 256-position digital potentiometers. Other variants in the series include models with 5 kΩ, 10 kΩ, and 100 kΩ resistances, such as the AD5160BRJZ5 and AD5160BRJZ100. The BRJZ designation indicates the commercial temperature grade and SOT-23 package type.

Replacement Considerations

Direct pin-compatible substitutes within the same family include AD5160BRJZ50-RL7, which shares identical electrical specifications but differs in shipping packaging format.
