Product specification
Advanced modem/audio analog front-end
UCB1200
The applied voltage on the four analog inputs of the UCB1200 (AD0 - AD3) is attenuated before it is applied to the ADC
input multiplexer using on chip resistive dividers.These high voltage inputs are optimized to handle voltages larger than
the applied supply voltage. The built-in resistive voltage dividers are only activated if the corresponding analog input is
selected. The resistive dividers are made floating when the input is not selected by the ADC input multiplexer, such that
the input leakage of these high voltage analog pins is minimized. This makes these analog inputs very suitable to monitor
battery voltage voltages.
