APPLICATIONS INFORMATION
Output Driver Power
Separate output power and ground pins allow the output
drivers to be isolated from the analog circuitry. The power
supply for the digital output buffers, OV
DD
, should be tied
to the same power supply as for the logic being driven.
For example, if the converter is driving a DSP powered
by a 1.8V supply, then OV
DD
should be tied to that same
1.8V supply. In CMOS mode OV
DD
can be powered with
any logic voltage up to the V
DD
of the ADC. OGND can be
powered with any voltage from ground up to 1V and must
be less than OV
DD
. The logic outputs will swing between
OGND and OV
DD
.
Internal Dither
The LTC2207-14/LTC2206-14 are 14-bit ADCs with a very
linear transfer function; however, at low input levels even
slight imperfections in the transfer function will result in
unwanted tones. Small errors in the transfer function are
usually a result of ADC element mismatches. An optional
internal dither mode can be enabled to randomize the input
location on the ADC transfer curve, resulting in improved
SFDR for low signal levels.
As shown in Figure 14, the output of the sample-and-hold
amplifier is summed with the output of a dither DAC. The
dither DAC is driven by a long sequence pseudo-random
