Analog Devices Inc. Analog Devices ADM3260 可热插拔数字和&电源隔离器
Analog Devices ADM3260 是一款支持热插拔的数字和电源隔离器，集成两路无闩锁、双向通信通道。ADM3260 基于 iCoupler® 和 isoPower® 芯片级变压器技术，提供完整的隔离式 I2C 接口和集成式隔离直流-直流转换器，支持最高 150 mW 的隔离式电源转换。拥有双向 I²C 通道则无需将 I²C 信号分成单独的发送信号与接收信号供独立光耦合器使用。ADM3260 的收发机可与半导体电路相集成，从而实现完整的 I²C 隔离式接口，并可在小尺寸内运行电源转换器。ADM3260 采用 20 引脚 SSOP 封装，并具有 -40 ℃ 至 +105 ℃ 的工作温度范围。
The bidirectional I²C channels eliminate the need for splitting I²C signals into separate transmit and receive signals for use with standalone optocouplers. ADM3260's transceivers can be integrated with semiconductor circuitry. This enables a complete isolated I²C interface and allows the power converter to be implemented in a small form factor. The ADM3260 is available in 20-lead SSOP package and has an operating temperature range of -40°C to+105°C.
