HCPL-788J-500E

Instrumentation, Op Amps, Buffer Amps Overview

The HCPL-788J-500E is a single-channel optically isolated amplifier manufactured by Broadcom Limited. It operates on a dual power supply ranging from 4.5 V to 5.5 V and utilizes a 16-pin SOIC surface-mount package with dimensions of 10.31 mm in length and 3.51 mm in height. The device features an input offset voltage (Vos) of 3 mV and a common-mode rejection ratio (CMRR) of 85 dB. It functions within a temperature range of -40°C to 85°C and draws a typical operating supply current of 20 mA.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Provides galvanic isolation between input and output circuits using optical transmission technology.
• Delivers linear signal amplification with low input offset voltage for precision applications.
• Offers high common-mode rejection capability to suppress noise interference.

Instrumentation, Op Amps, Buffer Amps Applications

• Industrial process control systems requiring isolated analog signal conditioning
• Medical equipment needing safe patient isolation channels
• Test and measurement instrumentation

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix '500E' against official datasheets to confirm reel packaging specifications. Ensure compatibility with the required 16-pin SOIC footprint during PCB layout. Confirm that the 4.5 V to 5.5 V dual supply requirement aligns with the target system design before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel isolated amplifier with 85 dB CMRR is required. Compare the 3 mV Vos specification against other models if higher precision is needed. Verify that the 20 mA supply current fits within the thermal budget of the application environment.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the HCPL-788J series of optically isolated amplifiers from Broadcom. It is distinct from logic-output optocouplers like the HCPL-0600, as it provides continuous analog signal transfer rather than digital switching. The series is designed for applications demanding high linearity and isolation integrity.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult official Broadcom documentation for verified substitute part numbers. Generic replacements may not match the specific 85 dB CMRR or 3 mV Vos characteristics. Ensure any alternative maintains the 16-pin SOIC form factor and dual-supply operation.
