ADG528F: 4/8 Channel Fault-Protected Analog Multiplexers
The ADG508F, ADG509F and ADG528F are CMOS analog multiplexers, the ADG508F and ADG528F comprising 8 single channels and the ADG509F comprising four differential channels. These multiplexers provide fault protection. Using a series n-channel, p-channel, n-channel MOSFET structure, both device and signal source protection is provided in the event of an overvoltage or power loss. The multiplexer can withstand continuous overvoltage inputs up to -40 V to +55 V. During fault conditions, the multiplexer input (or output) appears as an open circuit and only a few nanoamperes of leakage current will flow. This protects not only the multiplexer and the circuitry driven by the multiplexer, but also protects the sensors or signal sources which drive the multiplexer.
The ADG508F and ADG528F switch one of eight inputs to a common output as determined by the 3-bit binary address lines A0, A1 and A2. The ADG509F switches one of four differential inputs to a common differential output as determined by the 2- bit binary address lines A0 and A1. The ADG528F has on-chip address and control latches that facilitate microprocessor interfacing. An EN input on each device is used to enable or disable the device. When disabled, all channels are switched OFF.
