UCB1200
POWER ROUTING STRATEGY
The UCB1200 has nine power supply pins, since the UCB1200 contains five power supply regions within the circuit. The
analog and digital parts have their separate power supplies to reduce the interference between these parts. The speaker
driver circuit is powered separately (V
DDA2
/V
SSA2
) from the other analog circuit parts and the touch screen switch matrix
has its own ground pin (V
SSA3
). This separation in the analog part reduces the interference between the speaker driver
and the touch screen switch matrix, which has relatively large and fluctuating current consumption and the remaining
parts of the analog circuit.
