Charge Pump Current Specification Definitions
I1 = Charge Pump Sink Current at V
CPout
= Vcc - ΔV
I2 = Charge Pump Sink Current at V
CPout
= Vcc/2
I3 = Charge Pump Sink Current at V
CPout
= ΔV
I4 = Charge Pump Source Current at V
CPout
= Vcc - ΔV
I5 = Charge Pump Source Current at V
CPout
= Vcc/2
I6 = Charge Pump Source Current at V
CPout
= ΔV
ΔV = Voltage offset from the positive and negative supply rails. Defined to be 0.5 volts for this part.
v
CPout
refers to either V
CPoutRF
or V
CPoutIF
I
CPout
refers to either I
CPoutRF
or I
CPoutIF
