Analog Devices has introduced a quad-channel protector and two multiplexers offering A 55V overvoltage protection for precision converters, amplifiers and other components that operate from a voltage of 4.5V up to 36V. According to ADI the ADG5462F quad channel protector, ADG5248F 8:1 multiplexer and ADG5249F differential 4:1 multiplexer offer A 55V OVP in power-on and power-off stages and protect against hot-swapping and operator miss-use events, protecting downstream analogue components.
