The Broadcom® ACPL-C799T is a 1-bit, second-order sigma-delta (Σ-Δ) modulator which converts an analog input signal into a high-speed data stream with galvanic isolation based on the optical coupling technology. This isolated ADC delivers the reliability, small size, superior isolation, and over-temperature performance, allowing motor drive designers to accurately measure current. Broadcom R2Coupler™ isolation products provide the reinforced insulation and reliability needed for critical automotive and high-temperature industrial applications, in a compact SSO-8 package.
