The DS1867-100+ should be compared mainly with other DS1867 resistance options and related dual digital potentiometer devices. DS1867-10+ and DS1867-50+ share the same basic architecture, 3-wire serial interface, dual 256-position control, and EEPROM wiper storage, but offer lower resistance values for different analog impedance requirements. DS1867E-100+ is a useful comparison when the same 100kΩ function is needed in a surface-mount package instead of a 14-PDIP through-hole package.
DS1267-100+ is similar in digital potentiometer function, but the key selection difference is nonvolatile memory: DS1867 retains programmed wiper positions after power-down, while DS1267 is generally better suited for applications where stored power-off settings are not required. For legacy repair, prototyping, or socketed boards, DS1867-100+ is preferred; for compact SMT production, consider the surface-mount DS1867 package options.
Analog Devices DS1867-100+ Analog Devices / Maxim Integrated Dual 100kΩ Digital Potentiometer IC Overview
The DS1867-100+ is a dual digital potentiometer IC from Analog Devices / Maxim Integrated, designed to provide digitally controlled resistance adjustment in precision analog and mixed-signal circuits. It integrates two independent 100kΩ linear potentiometers, each with 256 tap positions, allowing electronic control of gain, offset, bias, signal level, and calibration settings without using mechanical potentiometers.
With its non-volatile memory, the DS1867-100+ can retain programmed wiper positions after power is removed, making it suitable for systems that require stable startup calibration or stored adjustment values. The device uses a simple 3-wire serial interface for digital control and operates from a 5V supply. Its 14-PDIP through-hole package is convenient for prototyping, repair, legacy equipment maintenance, and designs where socketed ICs or easy hand assembly are preferred.
The DS1867 series is commonly used in audio signal adjustment, RF level control, modem signal conditioning, operational amplifier trimming, power supply regulation, battery charging control, and general system calibration applications. The DS1867-100+ version provides a 100kΩ resistance value, making it suitable for higher-impedance signal control and adjustment networks. Analog Devices notes that the DS1867 can be used for modem input signal level control, RF and audio signal adjustment, battery charging control, tuning, calibration, op-amp offset trimming, gain control, and power supply regulation.

DS1867-100+ is a dual 100kΩ nonvolatile digital potentiometer IC with two independently controlled 256-position resistor networks. It supports 3-wire serial control for setting and reading wiper positions, while EEPROM memory helps retain the last programmed settings after power-down.
Designed for single +5V or ±5V operation, it is commonly used for digital trimming, calibration, gain control, audio/RF level adjustment, op-amp offset adjustment, power supply regulation, and legacy system repair. The “100” version provides a 100kΩ resistance value, making it suitable for higher-impedance analog control circuits. The device is supplied in a through-hole 14-PDIP package for prototyping, maintenance, and socketed designs.
