ANALOG-TO-DIGITAL CONVERTER (ADC)
The ADDI7100 uses a high performance ADC architecture
optimized for high speed and low power. Differential non-
linearity (DNL) performance is typically better than 0.5 LSB.
The ADC uses a 2 V full-scale input range.
VARIABLE GAIN AMPLIFIER (VGA)
The VGA stage provides a gain range of 6 dB to 42 dB, pro-
grammable 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.
VGA Gain (dB) = (VGA Code × 0.0358 dB) + 5.4 dB
where Code is in the range of 0 to 1023.

DIGITAL DATA OUTPUTS
By default, the digital output data is latched by the rising edge of
the DATACLK input. Output data timing is shown in Figure 3.
It is also possible to make the output data latch transparent,
immediately validating the data outputs from the ADC. Setting
the DOUTLATCH register (Address 0x01[5]) to 1 configures
the latch as transparent. The data outputs can also be disabled
by setting the DOUT_OFF register (Address 0x01[4]) to 1.
