Analog Devices 3B41-03 Isolated Wideband Voltage Input

Analog Devices 3B41-03 Isolated Wideband Voltage Input is a rugged front-end module in the 3B Series signal conditioning subsystem that provides galvanic isolation for real‑world voltage signals entering a measurement chain. Isolation is achieved via transformer coupling, delivering up to 1500 V peak isolation between the input and the measurement side, which helps protect downstream electronics and enable safe interfacing in mixed‑domain systems. The module is designed for wideband voltage input with a bandwidth of about 10 kHz, making it suitable for capturing relatively fast-changing signals in data acquisition, instrumentation, and process‑control applications. As part of the 3B40/3B41 family, it serves to condition and isolate the input signal before it reaches the ADC or data processor, supporting common use cases such as interfacing sensors or transducers to isolated front ends, instrumentation amplifiers, or isolated data acquisition modules.
