Description
The ACPL-C87B/C87A/C870 voltage sensors are optical
isolation amplifi ers designed specifi cally for voltage
sensing. Its 2 V input range and high 1 GW input impedance,
makes it 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 diff erential 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
amplifi ers, and diff erential outputs to provide unequaled
isolation-mode noise rejection, low off set, 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.
