Broadcom (HCPL-7800A-000E) Isolation Amplifier, Optically, 1 Amplifier

Isolation Amplifier, Optically, 1 Amplifier, 300 µV, 3.75 kV, 4.5V to 5.5V, DIP, 8 Pins Product Overview The HCPL-7800A-000E is an Isolation Amplifier for current sensing in electronic motor drives. The high CMR capability of isolation amplifier provides the precision and stability needed to accurately monitor motor current in high noise motor control environments, providing for smoother control in various types of motor control applications. In a typical implementation the motor current flows through an external resistor and the resulting analogue voltage drop is sensed by the amplifier. A differential output voltage is created on the other side of the amplifier optical isolation barrier. It is designed to ignore very high common-mode transient slew rates. 15kV/µs Common-mode rejection at VCM = 1000V Advanced sigma-delta A/D converter technology Compact and auto-insertable Fully differential circuit topology Applications Motor Drive & Control, Power Management, Industrial Product Information No. of Amplifiers: 1 Amplifier Input Offset Voltage: 300µV Isolation Voltage: 3.75kV Supply Voltage Range: 4.5V to 5.5V Amplifier Case Style: DIP No. of Pins: 8Pins Bandwidth: 100kHz Gain Non-Linearity Max: 0.35% Operating Temperature Min: -40°C Operating Temperature Max: 85°C
