12. Limiting values
[1]
All supply connections must be made to the same power supply.
[2]
ESD behavior is tested in accordance with JEDEC II standard:
a) Human Body Model (HBM); equivalent to discharging a 100 pF capacitor through a 1.5 k
series
resistor.
b) Machine Model (MM); equivalent to discharging a 200 pF capacitor through a 0.75
μ
H series inductor.
13. Thermal characteristics

PDLNA
Power-down voice LNA.
Bit PDLNA is to power-down the voice ADC
LNA. It should be noted that disabling the LNA requires a recovery
time defined by the external RC circuit.
1 = power-down
0 = power-on (default)
