AD5160BRJ10-R2

Overview

The AD5160BRJZ10-R2 is a single-channel, 8-bit digital potentiometer from Analog Devices. It provides 256 adjustable tap positions with a nominal end-to-end resistance of 10 kΩ and a tolerance of ±15%. 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 features an SPI-compatible 3-wire serial interface for wiper control and includes a power-on preset function that initializes the wiper to midscale. The component is housed in a compact 8-lead SOT-23 package and supports an operating temperature range from –40°C to +125°C.

Feature Summary

• 256-position resolution with linear taper and 10 kΩ nominal resistance
• SPI-compatible 3-wire serial interface (CS, SDI, CLK)
• Power-on preset to midscale for fault recovery
• Low power consumption: 3 µA typical supply current

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 ordering suffix '-R2' corresponds to the reel packaging format required for production integration. Confirm RoHS compliance status via the manufacturer's documentation. Ensure the 10 kΩ resistance variant matches the circuit design requirements, as other values such as 5 kΩ, 50 kΩ, and 100 kΩ are available within the same family.

Selection Notes

Select this component when a compact SOT-23-8 footprint is required for space-constrained PCB layouts. The 10 kΩ value is suitable for moderate impedance applications; lower or higher resistance options are available if system loading constraints differ. Verify that the host controller supports the SPI protocol with appropriate clock speeds up to 25 MHz. Consider the ±15% tolerance if precise absolute resistance is critical without calibration.

Part Context

This part belongs to the AD5160 series of 256-position digital potentiometers. It serves as a solid-state alternative to mechanical pots, offering enhanced reliability and low temperature coefficients. The 'BRJZ' designation indicates the industrial temperature grade (-40°C to +125°C) and RoHS-compliant SOT-23-8 package. The '10' suffix specifies the 10 kΩ resistance value, while '-R2' denotes the tape and reel packaging option.
