Analog Devices / Maxim Integrated 美信 MAX14661 单电源电轨 16:2 多路复用器
美信 MAX14661 单电源电轨 16:2 多路复用器是一款串行控制的双通道模拟多路复用器,其 16 个引脚能以不同组合方式同时连接至两个共同引脚中的一个。这款器件具有超摆幅™功能,因此±5.5V 信号可以通过电压在 +1.6V 和 +5.5V 之间的任何单电源。可以选择 I2C 或 SPI 进行串行控制。两种模式都能提供对独立开关的单独控制,因此适用于任何开关组合。I2C 模式有两个选址引脚,可以在一根总线上对四个器件进行寻址。SPI 模式则包括一个 DOUT 引脚,可以用来将多个器件与单个选择信号链接。特性
- Beyond-the-Rails technology reduces cost and complexity
- Switch ± 5.5V signals from a +1.6V single supply
- Wide +1.6V to +5.5V supply range
- Low 5.5Ω RON (Typ.) across the supply range
- Flexible multiplexing enables design reuse
- 16:2 matrix switch multiplexer connects any input pin to either common pin in any combination
- Each switch is independently controlled via I2C or SPI
- Programmable shadow registers allow simultaneous updating
- Low distortion switching improves system performance
- Total harmonic distortion + noise 0.005% (Typ.)
- RON flatness 2.5mΩ (Typ.) across a complete signal range
- Integrated protection for system reliability
- ±10kV HBM ESD protection on all AB_ and COM_Pins, even when powered down
应用
- Audio input selection
- Data acquisition
- I2C signal switching
- System diagnostics
