詳細說明

The REF102CU is a top-of-the-line precision 10V voltage reference that is perfect for demanding instrumentation and system reference applications. With a drift laser-trimmed to 2.5ppm/°C max C-grade over the industrial temperature range, this voltage reference achieves unparalleled precision without the need for a heater. Not only does this result in low power consumption, but it also offers fast warm-up, excellent stability, and low noise. The output voltage is extremely insensitive to both line and load variations, and can be externally adjusted with minimal effect on drift and stability, making it incredibly versatile for a wide range of uses. With single supply operation from 11.4V to 36V, the REF102CU offers outstanding overall specifications and is the ideal choice for applications requiring the highest level of precision and reliability

常見問題解答

What is REF102CU?

The REF102CU is a precision voltage reference integrated circuit manufactured by Texas Instruments. It is designed to provide a stable and accurate voltage reference for use in precision analog and mixed-signal circuits, such as A/D and D/A converters, power supplies, and industrial instrumentation.

How Does REF102CU Work?

The REF102CU works by producing a stable and precise output voltage that remains constant over time and temperature variations. It uses a bandgap voltage reference circuit combined with a precision amplifier to create a stable output voltage with low temperature drift and low output noise. This makes it suitable for providing a reliable reference voltage for various analog and mixed-signal applications.

How Many Pins does REF102CU have and What are the Functions of the Pinout Configuration?

The REF102CU is housed in an 8-lead SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

  • VOUT: Voltage reference output pin.
  • V+: Positive power supply pin.
  • V-: Negative power supply pin.
  • TRIM: Trim pin for adjusting the output voltage.
  • NC: No connect pin.
  • NC: No connect pin.
  • V-: Negative power supply pin.
  • VIN: Voltage input pin for the voltage reference.

What are the Pros and Cons of REF102CU?

Pros:

  • Precision: Provides a stable and accurate voltage reference for demanding precision applications.
  • Low Drift: Offers low temperature coefficient and low output noise for reliable performance over varying conditions.
  • Wide Operating Voltage Range: Can operate over a wide voltage range, making it versatile for different power supply configurations.
  • Compact Package: The 8-lead SOIC package is space-efficient and suitable for compact designs.

Cons:

  • External Components: May require additional external components for specific voltage reference and output range configurations.
  • Temperature Compensation: Requires careful consideration of temperature effects on the output voltage for certain applications.

Are There Any Equivalents/Alternatives to REF102CU for Recommendation?

  • The LM4040 from Texas Instruments is a similar precision voltage reference IC with different package options and features.
  • Alternatives to the REF102CU include the ADR4520 from Analog Devices and the MAX6126 from Maxim Integrated, both of which offer precision voltage references with comparable performance characteristics.
