詳細說明

The device's versatility is further underscored by its compatibility with isolated power supplies, effectively preventing noise currents from entering the local system ground and potentially damaging low-voltage circuitry. Furthermore, the AMC1304's integrated low-dropout regulator (LDO) allows for unregulated input voltages ranging from 4 V to 18 V, while the digital interface operates from a reliable 3.3-V or 5-V power supply

主要特徵

  • Precision sensing for industrial applications
  • Enhanced signal integrity and noise immunity
  • Suitable for high-precision measurement systems
  • Compact design ideal for space-constrained systems
  • Robust operation over extended temperature range
  • Easy integration with industrial control systems

常見問題解答

What is AMC1304M25DW?

The AMC1304M25DW is a precision delta-sigma modulator with an isolated sigma-delta modulator and modulator output. It is designed to provide accurate measurements for voltage and current signals in high-performance industrial applications, including motor control, power monitoring, and instrumentation.

How Does AMC1304M25DW Work?

The AMC1304M25DW works by converting analog voltage and current signals into digital data using a delta-sigma modulator. It provides high accuracy and noise immunity by combining isolation and modulator features, making it suitable for applications where precision measurements and isolation are essential.

How Many Pins does AMC1304M25DW have and What are the Functions of the Pinout Configuration?

The AMC1304M25DW is housed in a 16-pin wide SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

  • IN+: Positive input for the analog voltage or current signal.
  • IN-: Negative input for the analog voltage or current signal.
  • B+: Power supply pin for the input side of the isolation barrier.
  • B-: Ground pin for the input side of the isolation barrier.
  • A+: Power supply pin for the output side of the isolation barrier.
  • A-: Ground pin for the output side of the isolation barrier.
  • CLK: Clock input pin.
  • DOUT: Digital output pin.
  • AGND: Analog ground pin.
  • DGND: Digital ground pin.

What are the Pros and Cons of AMC1304M25DW?

Pros:

  • Isolation: Provides high isolation and common-mode rejection for accurate measurements in noisy environments.
  • Precision: Offers high-precision delta-sigma modulator for accurate digital data conversion.
  • Wide Supply Range: Supports a wide power supply range for flexibility in system design.
  • High Reliability: Designed to meet rigorous industrial standards for reliability and performance.

Cons:

  • Complexity: Requires careful consideration of isolation barrier and power supply design for optimal performance.
  • Cost: Precision isolation and modulation features may result in a higher cost compared to non-isolated solutions.
  • Layout Considerations: Layout and grounding are critical for achieving maximum performance and noise immunity.

Are There Any Equivalents/Alternatives to AMC1304M25DW for Recommendation?

  • The AMC1304M25 from Texas Instruments is a similar device with slightly different specifications.
  • Alternatives to the AMC1304M25DW include the ISO224 from Texas Instruments and the Si8920 from Silicon Labs.
