常見問題解答
What is DS1267-010?
The DS1267-010 is a dual digital potentiometer designed by Maxim Integrated. It features two nonvolatile, 256-tap, 100 kΩ digital potentiometers with packaged wiper settings. It is ideal for applications requiring digitally controlled resistance adjustments, such as gain control, offset adjustment, and filters in audio systems, instrumentation, and programmable power supplies.
How Does DS1267-010 Work?
The DS1267-010 works by providing digitally controlled variable resistance using a nonvolatile memory for wiper position storage. It allows the resistance values to be adjusted through a serial interface, enabling precise control and calibration in various electronic circuits. The device offers flexible configuration options and can be used in place of mechanical potentiometers with the added benefit of digital control.
How Many Pins does DS1267-010 have and What are the Functions of the Pinout Configuration?
The DS1267-010 is housed in a 14-pin TSSOP (Thin Shrink Small Outline Package) package. The pinout configuration includes:
- VH, VL: High and low sides of the potentiometer supply voltage.
- H, L: High and low sides of the potentiometer resistor terminal.
- W, W2: Wiper terminals for each potentiometer.
- UD, LD: Up/down control input for each potentiometer.
- U/D: Unique/dual address pin for device selection.
- SCL, SDA: Serial clock and serial data input/output for the I2C interface.
- GD: General purpose digital input/output.
What are the Pros and Cons of DS1267-010?
Pros:
- Digitally Controlled: Provides precise digital control over resistance settings.
- Nonvolatile Memory: Retains wiper position even when powered off, allowing for preset values to be stored.
- Compact Package: Housed in a space-efficient 14-pin TSSOP package, suitable for compact designs.
- Flexible Interface: Supports the I2C interface for easy integration into digital systems.
- Programmable Memory: Allows users to store and recall specific resistance settings, reducing the need for manual adjustments.
Cons:
- Resolution and Range: May have limitations in terms of resolution and resistance range compared to discrete resistors.
- Cost: Digital potentiometers may have a higher cost compared to traditional mechanical potentiometers.
- Complexity: Requires attention to the interface protocol and digital control in circuit design.
Are There Any Equivalents/Alternatives to DS1267-010 for Recommendation?
- The MCP4011 from Microchip Technology is a single-channel digital potentiometer with similar features.
- Alternatives to the DS1267-010 include the AD5243 from Analog Devices and the CAT5171 from ON Semiconductor.
