noise and ripple can be
kept below 1mV by bypassing the V

pin directly to the
analog ground plane with a 4.7

F tantalum with leads as
short as possible. Figures 7 and 8 show the effects of good
and poor V
CC
bypassing.
3. Analog Inputs
Because of the capacitive redistribution A/D conversion
techniques used, the analog inputs of the LTC1283 have
capacitive switching input current spikes. These current
spikes settle quickly and do not cause a problem.
However, if large source resistances are used or if slow
settling op amps drive the inputs, care must be taken to
insure that the transients caused by the current spikes
settle completely before the conversion begins.
Source Resistance
The analog inputs of the LTC1283 look like 65pF capacitor
(C
IN
) in series with a 500
resistor (R

) as shown in
Figure 9. C
IN
gets switched between the selected “+” and
“–” inputs once during each conversion cycle. Large
external source resistors and capacitances will slow the
settling of the inputs. It is important that the overall RC
time constants be short enough to allow the analog inputs
to completely settle within the allowed time.
