DS1803E-010+T&R

Digital Potentiometers Overview

The DS1803E-010+T&R is an addressable dual digital potentiometer from Analog Devices/Maxim Integrated, housed in a 14-pin TSSOP package. It features two independently controlled 256-position potentiometers with a total resistance of 10 kΩ. The device operates on a 2-wire serial interface (SDA/SCL) and supports supply voltages between 2.7V and 5.5V. It utilizes volatile memory for wiper position storage, resetting to the low-end terminal upon power-up. The component functions within an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Dual 256-position digitally controlled potentiometers
• Addressable via three hardware pins (A0, A1, A2)
• 2-Wire Serial Interface (I2C compatible)
• Volatile wiper position memory

Digital Potentiometers Applications

• Industrial control systems requiring remote resistance adjustment
• Audio volume or tone control circuits
• Calibration of analog signal paths

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors due to potential availability constraints. Confirm RoHS compliance status as indicated by the '+' suffix in the part number. Ensure packaging specifications match the Tape & Reel format required for automated assembly processes.

Digital Potentiometers Selection Notes

Select this model when dual independent potentiometers are required on a shared serial bus. The 10kΩ resistance value suits moderate impedance applications. Consider the volatile nature of the memory; if non-volatile retention is necessary, alternative models such as the DS1848 series should be evaluated instead.

Digital Potentiometers Part Context

This component belongs to the DS1803 family of addressable digital potentiometers. The 'E' suffix denotes the 14-pin TSSOP surface-mount package, while '+T&R' indicates lead-free construction supplied in tape and reel packaging. It serves as a solid-state replacement for mechanical potentiometers in space-constrained designs.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements include other variants within the DS1803 family, such as DS1803Z-010+ (SOIC package). For non-volatile requirements, the DS1848 series offers similar functionality with retained wiper positions.
