ACPL-7970-300E

Overview

The ACPL-7970-300E is an optically isolated amplifier from the Broadcom ACPL series, utilizing sigma-delta modulation technology. It operates within a temperature range of -40°C to +105°C and consumes 14 mA of supply current. The device is packaged in bulk format for surface-mount installation. As a specialized isolation amplifier, it provides signal transmission across electrical barriers while maintaining high precision and bandwidth characteristics suitable for demanding industrial applications.

Feature Summary

• Sigma-delta modulation architecture for high-precision isolation
• Wide operating temperature range from -40°C to +105°C
• Low power consumption with 14 mA supply current
• Surface-mount (SMD/SMT) installation style

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment needing precise signal isolation
• Power monitoring and protection circuits
• Data acquisition systems with high common-mode rejection requirements

Procurement Notes

Verify the specific package type and reel configuration when ordering, as the source indicates 'Bulk' packaging but other variants may use tubes or reels. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation prior to procurement. Ensure the supplier provides valid traceability documents for automotive or medical grade requirements if applicable.

Selection Notes

Select this component when high-speed, high-precision isolation is required compared to standard transistor-output optocouplers. Consider the 14 mA supply current against system power budgets. Verify that the sigma-delta modulation interface matches the downstream ADC or DSP requirements. Check thermal management needs given the +105°C maximum operating temperature limit.

Part Context

This part belongs to the Broadcom ACPL series of optically isolated amplifiers. It differs from the HCPL series which focuses on high-speed digital logic isolation. The ACPL-7970-300E is distinct from the ACPL-C797 series which uses different packaging options like SSO-8. It serves as a bridge between analog signals and digital processing domains with robust isolation capabilities.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult Broadcom's official replacement guide or contact technical support for qualified alternatives. Cross-referencing pinouts and isolation voltage ratings is essential when evaluating potential substitutes.
