FSA7830BUCX

FAIRCHILD SEMICONDUCTOR  FSA7830BUCX  Analog Multiplexer, 8:1, 1 Circuit, 200 ohm, 2.7V to 5.5V, WLCSP-16 新

The is an 8-channel voltage MUX with integrated voltage divider and OVP in 16 pin WLCSP package. This MUX integrates 8 analogue switches for input voltage selection and voltage dividers to provide 1/3, 2/3 fraction of selected voltage with another 3 analogue switches, FSA7830 provides feasibility to choose 1/3, 2/3 or 1 times of selected voltage. FSA7830 also contains output buffer to enhance driving capability. It features over voltage protection to ensure output less than 2V, interrupt will be alerted at the same time. FSA7830 supports 1.8V I2C interface to communicate with processor and 2 address pins to provide multi chip solution. It is used in cell phones and tablets.
