Isolation Amplifiers

R2Couplers™ isolation amplifiers send precision analog voltage and current measurement across an electrical isolation barrier.   The amplifier ‘s Sigma-Delta (Σ-Δ) architecture converts analog signals to digital signals and transmits across the isolation barrier.  The detector then processes the signals and converts back to analog or digital output.  Combined with superior optical coupling technology, the amplifier/modulator delivers excellent immunity against isolation mode transients.

These parts are qualified to AEC-Q100 Grade 1 test guidelines and suitable for hybrid and plug-in electric vehicles with operating temperature range of -40°C to +125°C. Broadcom R2CouplerTM isolation products provide the reinforced insulation and reliability needed for critical automotive and high temperature applications.
