DS1873T+T&R

Overview

The DS1873T+T&R is a digital potentiometer manufactured by Analog Devices Inc./Maxim Integrated. It features two independent functional channels, each offering 256 adjustable tap positions for precise resistance control. The component utilizes a 3-wire serial interface for communication and configuration. It is housed in a 16-pin SOIC package (PDSO16) with a standard lead pitch. The device operates within a specified temperature range up to 85 °C and complies with RoHS standards, indicating it is lead-free.

Feature Summary

• Dual-channel architecture providing two independent digital potentiometer functions within a single integrated circuit.
• Digital adjustment capability via a 3-wire serial control interface for simplified system integration.
• High-resolution positioning with 256 discrete tap settings available per channel.

Applications

• Programmable gain amplifier circuits requiring digital volume or attenuation control.
• Adjustable voltage reference networks in precision measurement systems.
• Calibration of sensor signal conditioning paths.

Procurement Notes

Verify the specific suffix and tape-and-reel designation against the manufacturer's current datasheet to ensure compatibility with automated assembly processes. Confirm that the 3-wire serial protocol matches the host controller's interface capabilities. Check for any recent lifecycle status updates or alternative package options from Analog Devices Inc./Maxim Integrated before finalizing procurement plans.

Selection Notes

Select this component when a dual-channel solution is required to save board space compared to using two separate single-channel devices. Ensure the application environment remains within the 85 °C maximum operating temperature limit. Verify that the 3-wire serial interface timing requirements are met by the system microcontroller or processor driving the device.

Part Context

This part belongs to the Maxim Integrated digital potentiometer family, designed for applications needing reliable, non-volatile-like adjustment without mechanical wear. The series typically includes variants with different resistance values and pin counts, but this specific model focuses on dual functionality in a compact SOIC-16 footprint.

Replacement Considerations

Consult official cross-reference lists from Analog Devices Inc./Maxim Integrated for verified substitutes. Generic digital potentiometers may not match the 3-wire interface or 256-position resolution without firmware changes.
