DS1267BE-010+T/R

Digital Potentiometers Overview

The DS1267BE-010+T/R is a dual digital potentiometer IC from the DS1267B series, manufactured by Analog Devices (Maxim Integrated). It features two independent 256-position (8-bit) digitally controlled potentiometers with a standard end-to-end resistance of 10kΩ. The device operates on a single +5V supply or ±5V supplies and communicates via a 3-wire serial interface (RST, CLK, DQ). Key electrical characteristics include a typical supply current of 5mA, standby current of 2µA, and an operating temperature range of -40°C to +85°C. The unit is housed in a 20-pin TSSOP package.

Digital Potentiometers Feature Summary

• Dual 256-position (8-bit) digitally controlled potentiometers
• 3-wire serial control interface for setting and reading wiper positions
• Stackable configuration allows connection in series for 512-step (9-bit) resolution
• Temperature compensated resistive elements with ±0.3 LSB relative linearity

Digital Potentiometers Applications

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

Digital Potentiometers Procurement Notes

Verify the component status as the source indicates limited availability or discontinuation for some variants in the DS1267 family. Confirm RoHS compliance (+ suffix) and ensure the specific tape-and-reel packaging matches production requirements. Cross-reference the manufacturer part number with authorized distributors to confirm current stock levels and lead times before finalizing procurement plans.

Digital Potentiometers Selection Notes

Select the DS1267BE-010+T/R when a dual-channel digital potentiometer with 10kΩ resistance is required. Choose this model over the DS1267BS variant if a 20-pin TSSOP surface-mount package is preferred over the 16-pin SO package. Ensure the application supports volatile memory behavior, as wiper positions reset to 50% upon power-up unless maintained by external logic.

Digital Potentiometers Part Context

This component belongs to the DS1267B family of dual digital potentiometers. It serves as the non-volatile EEPROM-based counterpart to the DS1867 series, although the DS1267B itself uses volatile storage that resets on power cycle. It is designed to replace mechanical potentiometers in automated assembly processes, offering processor-controlled adjustability and improved reliability in industrial environments.

Digital Potentiometers Replacement Considerations

The DS1267BE-010+ is functionally compatible with the DS1267S-010+ but differs in package type (TSSOP vs. SOIC). For through-hole replacements, consider the DS1867N-100, which offers similar functionality in a DIP-14 package. Verify pinout compatibility and voltage ratings when substituting with other digital potentiometer ICs.
