course, not under the 1606/1646 designer's control.
The 1606/1646's internal protection network will
withstand this abuse for coupling capacitors up to
about 33 uF.
incorporate larger values of capacitance, a pair
1N4004 diodes from each output to the supply rails,
as shown in Figure 9, is recommended. This shunts
the discharge current to the power supply bypass
and filter capacitors, thus protecting the output of
the 1606 or 1646. Note that Figure 9 shows a 1606,
but a 1646, with appropriate connection as shown in
Figure 4 or Figure 5, may be substituted.

or very long cables (several hundred feet) at high am-
bient temperatures (above 55°C) continuously could
lead to internal die temperatures that exceed the
maximum rating and result in performance degrada-
tion.
in which pins 1, 8, 9, and 16 are fused to the die
paddle to assist in conducting heat away from the
die. These pins are connected to the die substrate,
which is, in turn, connected to the ground pin of the
device. When these pins are connected to a top-side
ground plane of 1 square inch area, the junc-
tion-to-ambient thermal resistance is 125°C/watt. In-
ternal planes on multi-layer PCBs will reduce the
thermal resistance further.
