Broadcom HCPL-7800A-300E Isolation Amplifier 8-Pin DIP-8, 4.5 - 5.5V Optical, 3750Vrms, Through Hole

The Broadcom HCPL-7800A-300E isolation amplifier is engineered for precise signal isolation in demanding electronic applications. Featuring an 8-pin DIP package and an optical isolation structure, it delivers up to 3750Vrms isolation voltage, ensuring strong protection and interference immunity for sensitive analog signals. This device is equipped with a supply voltage range of 4.5V to 5.5V, making it compatible with standard logic and power systems commonly used in industrial and electronic designs.

Designed for through hole mounting, installation is straightforward and reliable, enhancing circuit robustness in industrial or high-reliability contexts. The amplifier achieves a remarkable common mode rejection ratio of 76dB, which enables accurate data transmission even in the presence of high common-mode transients or electrical noise. Its input offset voltage of 0.3mV and operating temperature range of -40°C to +100°C mean the part is well-suited for both precision measurement and control environments, as well as harsh temperature conditions.

The HCPL-7800A-300E is ideal for isolating and amplifying analog or metering signals in motor drives, inverters, power supplies, and energy monitoring equipment. Additionally, it can be effectively used for current/voltage sensing, feedback loops in power electronics, and general industrial isolation tasks where high CMRR and secure galvanic separation are critical. The compact DIP-8 package makes it easy to integrate into densely populated printed circuit boards, while the optical isolation technique ensures integrity and safety compliance. The device has 8 pins and uses a through-hole design to guarantee secure solder connections, reducing risk of vibration-related faults in heavy machinery environments.

Optical isolation prevents the transfer of high voltages or electrical surges between parts of a circuit, reducing risk of component failure and increasing system reliability. The amplifier is compliant with multiple international safety standards, supporting usage in regulated or certification-driven designs.

Typical use cases include industrial automation controls, power conversion systems, motor drive isolation, measurement equipment, energy management systems, and any electronic environment where robust signal isolation is essential for safety and performance.
