1.8 OUTPUT PINS
The ADC10080 has 10 TTL/CMOS compatible Data Output
pins. The offset binary data is present at these outputs while
the DF and STBY pins are low. While the t
OD
time provides
information about output timing, a simple way to capture a
valid output is to latch the data on the rising edge of the
conversion clock. Be very careful when driving a high ca-
pacitance bus. The more capacitance the output drivers
must charge for each conversion, the more instantaneous
digital current flows through V
DDIO
and V
SSIO
. These large
charging current spikes can cause on-chip ground noise and
couple into the analog circuitry, degrading dynamic perfor-
mance.Adequate bypassing, limiting output capacitance and
careful attention to the ground plane will reduce this prob-
lem. Additionally, bus capacitance beyond the specified
10 pF/pin will cause t
to increase, making it difficult to
properly latch the ADC output data. The result could be an
apparent reduction in dynamic performance. To minimize
noise due to output switching, minimize the load currents at
the digital outputs. This can be done by connecting buffers
between the ADC outputs and any other circuitry. Only one
driven input should beADC pins, will isolate the outputs from
trace and other circuit capacitances and limit the output
currents, which could otherwise result in performance deg-
radation.
