Product Description
The ACPL-C87B/C87A/C870 voltage sensors from Broadcom are optical isolation amplifiers designed specifically for voltage sensing.
The 2 V input range and high 1 GΩ input impedance make these sensors well suited for isolated voltage sensing requirements in electronic power converters applications including motor drives and renewable energy systems.
In a typical voltage sensing implementation a resistive voltage divider is used to scale the DC-link voltage to suit the input range of the voltage sensor. A differential output voltage that is proportional to the input voltage is created on the other side of the optical isolation barrier.
For general applications the ACPL-C87A (±1% gain tolerance) and the ACPL-C870 (±3% gain tolerance) are recommended. For high precision requirements the ACPL-C87B (±0.5% gain tolerance) can be used. The ACPL-C87B/C87A/C870 family operates from a single 5 V supply and provides excellent linearity.
An active-high shutdown pin is available which reduces the IDD1 current to only 15 mA making them suitable for battery-powered and other power-sensitive applications.
The high common-mode transient immunity (15 kV/μs) of the ACPL-C87B/C87A/C870 provides the precision and stability needed to accurately monitor DC-link voltage in high noise environments. Combined with superior optical coupling technology the ACPL-C87B/C87A/C870 implements sigma-delta modulation chopper stabilized amplifiers and differential outputs to provide unequalled isolation-mode noise rejection low offset high gain accuracy and stability.
This performance is delivered in a compact auto-insertable stretched SO-8 (SSO-8) package that meets worldwide regulatory safety standards.
