FAQs
What is BQ4013YMA-85?
The BQ4013YMA-85 is a nonvolatile digital potentiometer with 8-bit resolution designed by Texas Instruments. It is used for applications where digital control of resistance is required, such as in instrumentation, industrial control, and audio equipment.
How Does BQ4013YMA-85 Work?
The BQ4013YMA-85 works by utilizing nonvolatile memory to store the resistance settings, allowing the device to retain its settings even when the power is removed. It can be controlled digitally, enabling precise and reliable adjustment of resistance values in electronic circuits. The digital potentiometer offers flexibility in circuit design and simplifies system calibration.
How Many Pins does BQ4013YMA-85 have and What are the Functions of the Pinout Configuration?
The BQ4013YMA-85 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- A: Terminal A of the variable resistor.
- B: Terminal B of the variable resistor.
- W: Wiper terminal of the variable resistor.
- VH: High voltage supply pin.
- VSS: Ground pin.
- VW: Wiper supply pin.
- NC: No connect pin.
- NC: No connect pin.
What are the Pros and Cons of BQ4013YMA-85?
Pros:
- Nonvolatile Memory: Retains resistance settings without the need for continuous power.
- Digital Control: Allows for precise and reliable adjustment of resistance values.
- Space-Efficient Package: The 8-pin SOIC package is compact and suitable for space-constrained designs.
Cons:
- Limited Resolution: 8-bit resolution may not be sufficient for certain high-precision applications.
- Operating Voltage Limitations: May not be suitable for high-voltage applications due to the specified voltage range.
Are There Any Equivalents/Alternatives to BQ4013YMA-85 for Recommendation?
- The MCP4018 from Microchip Technology is a similar 8-bit nonvolatile digital potentiometer.
- Alternatives to the BQ4013YMA-85 include the AD5246 from Analog Devices and the MAX5400 from Maxim Integrated.
