For applications where a DC component of the input
signal is present, Figures 4 and 5 show single-ended
and differential DC-coupled input circuits. The ampli-
fiers’ input common-mode voltage range extends from
1.75V to 2.75V. To prevent attenuation of the input
signal’s DC component in this mode, disable the offset-
correction amplifier by grounding the _OCC+ and
_OCC- pins for the I and Q blocks (Figures 4 and 5).
ADCs
The I and Q ADC blocks receive the analog signals
from the respective I and Q input amplifiers. The ADCs
use flash conversion with 63 fully differential compara-
tors to digitize the analog input signal into a 6-bit output
in offset binary format.
