Broadcom Optically Isolated Amplifier DIP-8, 300µV, 3.75kV

The Broadcom Optically Isolated Amplifier is a high-performance single-channel device engineered for precision measurement in electrically noisy environments. It utilises advanced optical isolation technology to provide a robust barrier, supporting an isolation voltage of 3.75kV RMS and an impressive common-mode rejection of 15kV/µs at 1000V. This makes it exceptionally effective at rejecting interference and protecting sensitive downstream circuitry.

At its core is a sophisticated sigma-delta analogue-to-digital converter, ensuring high accuracy and stability. The device offers a low input offset voltage of just 300µV and a maximum gain non-linearity of 0.35%, delivering reliable and precise signal amplification. Its fully differential circuit topology further enhances noise immunity and signal integrity.

Housed in a compact, industry-standard DIP-8 package, this amplifier is designed for through-hole mounting and is fully auto-insertable, facilitating efficient and reliable PCB assembly. It operates from a single 4.5V to 5.5V supply and functions across a broad temperature range from -40°C to +85°C, making it suitable for demanding industrial, medical, and instrumentation applications.
