ACPL-C797T-000E

Overview

The ACPL-C797T-000E is a precision isolated amplifier manufactured by Broadcom Limited, utilizing sigma-delta modulation technology. It features an 8-pin SOIC stretched package and operates within a supply voltage range of 4.5 V to 5.5 V. The device supports a wide operating temperature range from -40°C to +105°C. Designed for high-performance isolation, it serves as a replacement for Hall effect sensors in industrial applications requiring precise current and voltage measurement.

Feature Summary

• Sigma-delta modulation architecture for high-precision signal isolation
• AEC-Q100 qualified for automotive reliability standards
• 8-pin stretched SOIC surface-mount package
• Wide operating temperature range: -40°C to +105°C

Applications

• Motor drive systems
• Power supply inverters
• Current and voltage sensing in industrial converters

Procurement Notes

Verify the specific suffix 'T' indicates the stretched SOIC package variant when sourcing. Confirm AEC-Q100 qualification status if automotive compliance is required for the final assembly. Check manufacturer documentation for lead times and minimum order quantities as these are subject to change based on production schedules.

Selection Notes

Select this component when high common-mode rejection and precision are needed in electrically noisy environments. Ensure the system design accommodates the 4.5 V to 5.5 V dual supply requirement. Compare performance metrics against standard Hall effect sensors to validate cost and size benefits for the specific application.

Part Context

This part belongs to the Broadcom ACPL-C79x series of optically isolated amplifiers. These devices are engineered to replace traditional magnetic sensors, offering superior linearity and bandwidth. The series is widely used in power electronics where galvanic isolation between control and power stages is critical.

Replacement Considerations

Direct pin-to-pin replacements may include other parts from the ACPL-C79x family with different package options or qualification levels. Verify electrical parameters such as offset voltage and bandwidth before substituting with non-Broadcom alternatives.
