Broadcom (ACPL-C87A-000E) Isolation Amplifier, Optically, 1 Amplifier

Isolation Amplifier, Optically, 1 Amplifier, -300 µV, 5 kV, 3V to 5.5V, SOIC, 8 Pins Product Overview The ACPL-C87A-000E is a precision optically isolated Voltage Sensor, designed specifically for voltage sensing. Its 2V input range and high 1GR 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. The high common-mode transient immunity (15kV/us) of this provides the precision and stability needed to accurately monitor DC-link voltage in high noise environments. Combined with superior optical coupling technology, this implements sigma-delta modulation, chopper stabilized amplifiers. 0.5% High gain accuracy Unity gain 1V/V -35ppm/°C Low gain drift -0.3mV Input offset voltage Advanced sigma-delta A/D modulation technology 15kV/µs Common-Mode transient immunity Applications Sensing & Instrumentation, Test & Measurement, Industrial Product Information No. of Amplifiers: 1 Amplifier Input Offset Voltage: -300µV Isolation Voltage: 5kV Supply Voltage Range: 3V to 5.5V Amplifier Case Style: SOIC No. of Pins: 8Pins Bandwidth: 100kHz Gain Non-Linearity Max: 0.1% Operating Temperature Min: -40°C Operating Temperature Max: 105°C Product Range: ACPL-C87B; ACPL-C87A; ACPL-C870
