ACPL-7970-000E

Overview

The Broadcom ACPL-7970-000E is a single-channel optically isolated amplifier featuring an integrated sigma-delta modulator. It operates on dual power supplies ranging from 3 V to 5.5 V with a typical quiescent current of 14 mA. The device provides high-voltage isolation and is housed in a through-hole package suitable for industrial environments. It functions within a temperature range of -40°C to +105°C, delivering analog-to-digital conversion capabilities directly across the isolation barrier.

Feature Summary

• Integrated Sigma-Delta Modulator for direct analog-to-digital signal transmission
• High voltage optical isolation barrier
• Dual supply operation between 3 V and 5.5 V
• Extended industrial temperature range (-40°C to +105°C)

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment with strict safety isolation requirements
• Power monitoring and measurement circuits

Procurement Notes

Verify the specific package type and pinout configuration against the official datasheet before integration, as variations exist within the ACPL-79xx family. Confirm that the required isolation voltage rating meets the system's safety standards. Ensure the design accommodates the necessary dual power supply rails for proper operation.

Selection Notes

Select this component when high-speed digital output is preferred over analog transmission across an isolation barrier. The sigma-delta architecture allows for robust noise immunity in electrically noisy environments. Compare performance metrics such as bandwidth and offset voltage against other models like the ACPL-796J if surface-mount packaging is required instead of through-hole.

Part Context

This part belongs to the Broadcom ACPL series of optocouplers and isolators. It is distinct from standard logic gate optocouplers by incorporating internal modulation circuitry. The model number suffix '000E' typically denotes the specific package variant and lead-free compliance status defined by the manufacturer.
