A Robust, Low Power, Battery Monitoring Circuit Front End Using ADG5409 Analog Multiplexer

Application Circuit is a robust battery monitoring front end designed for environments where transients are likely to occur, such as in industrial or process automation environments. The circuit uses the ADG5409, 8-channel CMOS multiplexer followed by the AD8226 instrumentation amplifier to provide accurate voltage monitoring of individual cells at low power and low cost and requires no additional external transient protection circuitry
