Broadcom ACNT-H87x Voltage Sensors are optical isolation amplifiers designed for voltage sensing. The voltage sensors work from a single 5V supply and provide good linearity. These ACNT-H87x sensors offer an active-high shutdown pin, 1GΩ input impedance, and operate from 0V to 2V input voltage range. The ACNT-H87x sensors are available in a compact auto-insertable SO-8 package with 15mm creepage and 14.2mm clearance. These voltage sensors employ a resistive voltage divider that scales the DC-link voltage to suit the input range of the voltage sensor. A differential output voltage proportional to the input voltage is created on the other side of the optical isolation barrier. Typical applications include isolated voltage sensing in AC and servo motor drives, isolated sensor interfaces, and signal isolation in data acquisition systems.
