Description
Not Connected. Free, high impedance for normal operation. Used for
internal test purpose.
Low-Noise Analog Ground
DAC-Controlled Input. Reference voltage for buck converter. The output of
the PA step-down converter is regulated to 2.5 x V REFIN . Bypass mode is
enabled when V IN ≤ 2.69V x V REFIN .
Power Ground for PA Step-Down Converter
10mA LDO Regulator 2 Output. Connect LDO2 with a 0.1 μ F ceramic
capacitor as close as possible to LDO2 and AGND. LDO2 is internally pulled
down through a 100 Ω resistor when this regulator is disabled.
PA Step-Down Converter Enable Input. For normal operation, connect to
logic-high. For shutdown mode, connect to logic-low. The pin is internally
pulled down through a 110k Ω resistor.
Enable Input for LDO2. For normal operation, connect to logic-high. For
shutdown mode, connect to logic-low. The pin is internally pulled down
through a 110k Ω resistor.
Inductor Connection. Connect an inductor from LX to the output of the PA
step-down converter.
