ACPL-C799U-500E

Overview

The ACPL-C799U-500E is a single-channel optically isolated amplifier from the Broadcom ACPL series, featuring an integrated Sigma-Delta analog-to-digital converter (ADC) output. It operates on a supply voltage range of 3 V to 5.5 V and provides a bandwidth of 10 MHz with an input offset voltage of 10 mV. The device utilizes SSO-8 surface-mount packaging and supports operation within a temperature range of -40°C to +125°C. It offers 5000 Vrms isolation voltage and complies with IEC standards.

Feature Summary

• Integrated Sigma-Delta ADC for digital output
• 10 MHz bandwidth with 10 mV input offset voltage
• 5000 Vrms isolation voltage rating
• Extended operating temperature range up to +125°C

Applications

• Industrial process control systems
• Power monitoring and measurement equipment
• Medical instrumentation requiring galvanic isolation

Procurement Notes

Verify the specific ordering suffix 'U-500E' against the manufacturer's current datasheet to confirm tape-and-reel packaging and IEC certification status. Ensure compatibility with the required SSO-8 footprint and thermal management specifications for the target application environment.

Selection Notes

Select this component when a digital output interface is preferred over analog signals in high-noise environments. The 10 MHz bandwidth suits applications requiring fast signal acquisition, while the wide temperature range supports harsh industrial conditions. Confirm that the system logic levels are compatible with the digital output format.

Part Context

This part belongs to the Broadcom ACPL family of optically isolated amplifiers. It distinguishes itself by incorporating a Sigma-Delta modulator, converting the amplified signal directly into a digital bitstream. This design reduces sensitivity to electromagnetic interference compared to traditional analog isolators.

Replacement Considerations

Cross-reference with other ACPL-C79x series variants for pin-compatible alternatives. Verify if different output types or bandwidth requirements necessitate models like ACPL-C79A or ACPL-C79B.
