AD5162BRM50

Overview

The AD5162BRM50 is a dual-channel, 8-bit SPI digital potentiometer with a nominal end-to-end resistance of 50 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 maximum supply current of 6 µA and maintains a low temperature coefficient of 35 ppm/°C. Encased in a compact 10-lead MSOP package (3 mm × 4.9 mm), it supports full read/write access to the wiper register via a 3-wire serial interface. The unit includes power-on preset functionality to midscale and is qualified for automotive applications.

Feature Summary

• Dual-channel architecture with 256-position adjustment capability
• SPI-compatible 3-wire serial interface for digital control
• Low power consumption with 6 µA maximum supply current
• Compact 10-lead MSOP package suitable for space-constrained designs

Applications

• Systems calibrations and electronics level settings
• Replacement for mechanical trimmers in new PCB designs
• Transducer adjustment for pressure, temperature, and optical sensors
• RF amplifier biasing and gain control offset adjustment

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific ordering suffix matches the required resistance value and packaging format. Check for RoHS compliance status relevant to the manufacturing date code. Ensure storage conditions adhere to moisture sensitivity levels to prevent package damage prior to soldering.

Selection Notes

Select this model when a 50 kΩ nominal resistance is required for the dual-potentiometer configuration. Verify that the system power supply remains within the 2.7 V to 5.5 V operational range. Consider the 35 ppm/°C temperature coefficient for precision applications. Evaluate the MSOP-10 footprint against available PCB real estate constraints.

Part Context

This component belongs to the AD5162 family of dual, 256-position digital potentiometers. Variants within the series differ primarily by end-to-end resistance values, including 2.5 kΩ, 10 kΩ, and 100 kΩ options. All variants share identical pinouts, interface protocols, and general electrical characteristics, allowing for design flexibility across different impedance requirements.

Replacement Considerations

Direct functional substitutes include other AD5162 variants with different resistance values if circuit impedance allows. Cross-referencing with Maxim Integrated MAX5488 series may be necessary for non-volatile memory requirements, though interface and pinout compatibility must be verified.
