DS1267-100 is the 100kΩ 14-PDIP version of the DS1267 dual digital potentiometer family. DS1267-10 and DS1267-50 offer the same basic dual 256-tap, 3-wire serial architecture with lower resistance values of 10kΩ and 50kΩ, making them suitable when the design requires a different end-to-end resistance. DS1267S-100 is useful for comparing the same 100kΩ function in a surface-mount package instead of through-hole DIP. DS1867-100 is a related dual digital potentiometer option with nonvolatile EEPROM memory, making it more suitable when the wiper setting must be retained after power is removed.
Analog Devices DS1267-100 Digital Potentiometer, 100kΩ Dual 256-Tap 14-PDIP Overview
The DS1267-100 is a dual digital potentiometer from Maxim Integrated / Dallas Semiconductor, now under Analog Devices. It integrates two digitally controlled solid-state potentiometers in one device, with each potentiometer providing 256 wiper positions. The wiper positions are controlled through a 3-wire serial interface, allowing a processor or controller to set and read the resistance position without using a mechanical potentiometer.
The “100” version of the DS1267 series provides a nominal 100kΩ end-to-end resistance. The device is designed for applications that require digitally adjustable resistance, signal attenuation, gain control, trimming, calibration, or replacement of mechanical potentiometers. According to the manufacturer documentation, the two potentiometers can also be connected in series to increase total resistance while maintaining digital control.
DS1267-100 operates from a 4.5V to 5.5V supply and supports an industrial operating temperature range of -40°C to +85°C. It uses volatile memory, meaning the programmed wiper positions are not retained after power is removed unless restored by the system controller. The 14-PDIP package makes this version suitable for through-hole PCB designs, repair work, prototyping, and legacy equipment maintenance.
Please note that DS1267-100 is listed by distributors as obsolete / no longer manufactured, so availability may depend on remaining stock, surplus inventory, or replacement sourcing.
