ACPL-C870-500E [Broadcom]

The Broadcom® ACPL-C87B/C87A/C870 voltage sensors are optical isolation amplifiers designed specifically for voltage sensing. Its 2V input range and high 1-GΩ input impedance, makes it well suited for isolated voltage sensing requirements in electronic power converters applications, including motor drives and renewable energy systems. The family operates from a single 5V supply and provides excellent linearity. An active-high shutdown pin reduces current to only 15µA, making them suitable for battery-powered applications. The high common-mode transient immunity (15 kV/µs) provides precision and stability needed to accurately monitor DC-link voltage in high noise environments. Combined with superior optical coupling technology, the devices implement sigma-delta (Σ-Δ) modulation, chopper stabilized amplifiers, and differential outputs to provide unequaled isolation-mode noise rejection, low offset, high gain accuracy and stability. This performance is delivered in a compact, auto-insertable Stretched SO-8 package that meets worldwide regulatory safety standards.
