A/D CONVERTER
The ADC uses a 2 V input range. Better noise performance
results from using a larger ADC full-scale range. The ADC uses
a pipelined architecture with a 2 V full-scale input for low noise
performance.

VARIABLE GAIN AMPLIFIER
The VGA stage provides a gain range of 6 dB to 40 dB,
programmable with 10-bit resolution through the serial digital
interface. The minimum gain of 6 dB is needed to match a 1 V
input signal with the ADC full-scale range of 2 V. A plot of the
VGA gain curve is shown in Figure 13.
