DS1267BS-010+

Digital Potentiometers Overview

The DS1267BS-010+ is a dual digital potentiometer IC from the DS1267B series, manufactured by Analog Devices Inc./Maxim Integrated. It features two independent 256-position (8-bit) solid-state potentiometers with a standard end-to-end resistance of 10kΩ. The device operates on a single +5V supply (4.5V to 5.5V) and communicates via a 3-wire serial interface (RST, CLK, DQ). It supports stacked configurations for increased resolution and cascading for multi-device control. The component is housed in a 16-pin SO package and functions within an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Dual 256-position digital potentiometers with 10kΩ resistance
• 3-wire serial interface for setting and reading wiper positions
• Stackable design allows connection in series for 512-step resolution
• Cascading capability enables control of multiple devices via a single processor

Digital Potentiometers Applications

• Variable gain amplifier circuits
• Fixed gain attenuator applications
• Battery charging and control circuitry
• Offset trimming of operational amplifiers

Digital Potentiometers Procurement Notes

Verify the specific suffix 'S' confirms the 16-pin SO package variant rather than the TSSOP option. Confirm RoHS compliance status associated with the '+' designation. Check current availability as distribution channels may vary for this discontinued or legacy part number.

Digital Potentiometers Selection Notes

Select this model for designs requiring dual 10kΩ digital pots in a surface-mount SO package. Ensure the system voltage remains between 4.5V and 5.5V. Consider the stacked configuration if higher resolution is needed, or cascade mode for expanding channel count without additional microcontroller pins.

Digital Potentiometers Part Context

This component belongs to the DS1267B family, which includes variants with different resistance values (10kΩ, 50kΩ, 100kΩ) and packages (SO, TSSOP). The 'BS' suffix specifically denotes the 16-pin Small Outline package with 10kΩ resistance, distinguishing it from the BE (TSSOP) or other resistance codes.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements include other DS1267B series parts such as DS1267BE-010+ (same function, TSSOP package) or DS1267S-010+ (older generation, SO package). Verify package footprint differences when substituting between SO and TSSOP variants.
