1.11 QUIET INTERFACE MODE
To improve performance at High Speed, operate the ADC in
Quiet Interface Mode. This mode provides improved INL and
DNL performance in I
face mode provides a maximum throughput rate of 162ksps.
Figure 17 describes how to read the conversion result register
in this mode. Basically, the Master needs to release SCL for
2
C Hs-Mode (3.4MHz). The Quiet Inter-

at least 1µs before the MSB of every upper data byte. The
diagram assumes that the address pointer register is set to
its default value.
Quiet Interface mode will only improve INL and DNL perfor-
mance in Hs-Mode. Standard and Fast mode performance is
unaffected by the Quiet Interface mode.
