ACPL-C797-500E

Overview

The Broadcom ACPL-C797-500E is a 16-bit isolated modulator designed for high-speed data acquisition and control applications. It integrates a sigma-delta modulator with an optical isolation barrier, providing galvanic isolation between input and output stages. The device operates on a single supply voltage and features a compact 8-pin SOIC package. Key electrical characteristics include a 10 MHz data rate capability and 16-bit resolution, making it suitable for precision measurement systems requiring robust noise immunity and signal integrity in electrically noisy environments.

Feature Summary

• Integrated 16-bit sigma-delta modulator with optical isolation
• High-speed operation with up to 10 MHz data rate
• Compact 8-pin surface-mount SOIC package
• Single-supply voltage operation

Applications

• Industrial process control systems
• Medical equipment requiring patient isolation
• Power electronics monitoring and control
• Data acquisition modules in harsh electromagnetic environments

Procurement Notes

Verify the specific suffix '500E' indicates the tape-and-reel packaging configuration when ordering. Confirm RoHS compliance status through official Broadcom documentation or authorized distributor datasheets prior to procurement. Ensure compatibility with existing PCB footprint designs for the 8-SOIC package. Check for any recent lifecycle notices regarding obsolescence or last-time buy dates from the manufacturer.

Selection Notes

Select this component when 16-bit resolution and high-speed digital isolation are required in a single package. Compare against discrete solutions involving separate ADCs and optocouplers for size and cost efficiency. Consider the operating temperature range and supply voltage requirements relative to the target application environment. Evaluate the need for additional external filtering components based on system noise specifications.

Part Context

The ACPL-C797 series belongs to Broadcom's portfolio of isolated analog-to-digital converters and modulators. These devices bridge the gap between traditional discrete isolation techniques and integrated mixed-signal solutions. The C797 variant specifically targets applications needing high-resolution data conversion with inherent galvanic isolation, simplifying board layout and improving system reliability compared to multi-component approaches.

Replacement Considerations

Consult Broadcom's official cross-reference guides for direct pin-compatible alternatives. Verify that any substitute maintains the same 16-bit resolution and 10 MHz data rate specifications. Ensure the replacement device offers equivalent isolation voltage ratings and operates within the same supply voltage constraints.
