ACPL-C797T-500E

Overview

The ACPL-C797T-500E is a 16-bit, 10 MSPS optically isolated modulator manufactured by Broadcom Limited. Housed in an 8-pin SOIC package, this device integrates a high-speed LED driver and a precision ADC for signal transmission across isolation barriers. It supports AEC-Q100 automotive qualification standards, ensuring reliability in demanding environments. The component operates within a temperature range of -40°C to 105°C and utilizes a single-ended output configuration. Key electrical characteristics include a maximum forward voltage of 5.5V and a typical rise/fall time of 1.7μs, facilitating high-speed digital communication with robust galvanic isolation.

Feature Summary

• 16-bit resolution with 10 MSPS data rate for high-speed isolated modulation
• AEC-Q100 qualified for automotive applications
• Integrated LED driver and precision ADC in a single 8-pin SO package
• Operating temperature range from -40°C to 105°C

Applications

• Automotive isolated sensor interfaces
• High-speed industrial control systems requiring galvanic isolation
• Precision measurement equipment with digital output requirements

Procurement Notes

Verify the specific suffix '500E' corresponds to the tape-and-reel packaging format containing 1000 units per reel. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to integration. Ensure supply chain sources provide valid traceability documentation for automotive-grade components.

Selection Notes

Select this component when high-resolution (16-bit) and high-speed (10 MSPS) data transfer across isolation barriers is required. Compare against standard optocouplers if analog-to-digital conversion at the isolated side is necessary. Verify that the 8-pin SOIC footprint and 5.5V max forward voltage align with the target PCB design and power budget constraints.

Part Context

This part belongs to the Broadcom ACPL series of optically isolated amplifiers and modulators. It serves as a specialized solution for converting analog signals into digitally encoded optical transmissions, distinct from simple logic-level optocouplers like the ACPL-217. The 'T' suffix typically denotes reel packaging, while '500E' indicates specific environmental or packaging variants.

Replacement Considerations

Direct pin-to-pin replacements are not explicitly listed in available public records. Evaluate other ACPL-C79x family members for functional compatibility. Verify that any substitute maintains the 16-bit resolution, 10 MSPS speed, and AEC-Q100 qualification if automotive use is intended.
