Example1:Full‐swingLVCMOS

• Vdd = 1.8V

• Idd Core = 900nA

• Load Capacitance = 10pF

• Idd Output Driver: (65nA/V)(1.8V) = 117nA

• Load Current: (10pF)(1.8V)(32.768kHz) = 590nA

• Total Current = 900nA+117nA+590nA = 1.6µA

Example2:NanoDrive™ReducedSwing

• Vdd = 1.8V

• Idd Core = 900nA

• Load Capacitance = 10pF

• Idd Output Driver: (65nA/V)(0.5V) = 33nA

• Load Current: (10pF)(0.5V)(32.768kHz) = 164nA

• Total Current = 900nA + 33nA + 164nA = 1.1µA
