Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix '300E' corresponds to the tube packaging variant, as other suffixes like '500E' indicate reel or cut tape options. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to integration. Ensure the DIP-8 Gull Wing footprint matches the target PCB design constraints. Cross-reference the part number with the latest Broadcom documentation to confirm active status and any potential product change notices affecting specifications or availability.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when analog signal isolation with amplification is required in a compact form factor. The 2 mV input offset voltage supports precision measurements where low drift is critical. The 18.31 dB gain setting eliminates the need for external amplification stages in many configurations. Consider the 16 mA supply current for power budget calculations in battery-operated or thermally constrained environments. Verify that the 4.5 V to 5.5 V supply range aligns with the system's power rails.

Instrumentation, Op Amps, Buffer Amps Part Context

This device is part of the Broadcom HCPL series of optoelectronic components. The HCPL family includes various optocouplers and isolated amplifiers designed for industrial and commercial applications. The HCPL-7800 specifically addresses the need for linear isolation, distinguishing it from digital logic isolators within the same portfolio. It serves as a bridge between low-voltage control circuits and higher-voltage or noisy industrial environments.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

HCPL-7800A-500E is listed as a related variant with similar isolation amplifier functionality but may differ in packaging or specific electrical tolerances such as input offset voltage. Verify pinout compatibility and exact parameter matching before substitution. No other direct substitute part numbers are confirmed in the provided data.
