Broadcom (HCPL-7840-000E) Isolation Amplifier, Optically, 1 Amplifier

Isolation Amplifier, Optically, 1 Amplifier, 300 µV, 3.75 kV, 4.5V to 5.5V, DIP,8 PinsProduct OverviewThe HCPL-7840-000E is an Isolation Amplifier for current sensing in electronicmotor drives. The high CMR capability of isolation amplifier provides theprecision and stability needed to accurately monitor motor current in high noisemotor control environments, providing for smoother control in various types ofmotor control applications. In a typical implementation the motor current flowsthrough an external resistor and the resulting analogue voltage drop is sensedby the amplifier. A differential output voltage is created on the other side ofthe amplifier optical isolation barrier. It is designed to ignore very highcommon-mode transient slew rates.15kV/µs Common-mode rejection at VCM = 1000VAdvanced sigma-delta A/D converter technologyCompact and auto-insertableFully differential circuit topologyApplicationsMotor Drive & Control, Power Management, IndustrialProduct InformationNo. of Amplifiers: 1 AmplifierInput Offset Voltage: 300µVIsolation Voltage: 3.75kVSupply Voltage Range: 4.5V to 5.5VAmplifier Case Style: DIPNo. of Pins: 8PinsBandwidth: 100kHzGain Non-Linearity Max: 0.35%Operating Temperature Min: -40°COperating Temperature Max: 85°C
