Broadcom Optočlen, řada: ACNT-H87A, počet kolíků: 8 kolíkový, počet kanálů: 1 Povrch

The Broadcom ACNT-H87A voltage sensors are optical isolation amplifiers designed specifically for voltage sensing. Its 2V 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 differential output voltage that is proportional to the input voltage is created on the other side of the optical isolation barrier.
