Notes:
1)
There are circuit parts with increasing supply current over temperature. The resulting supply current is
IS(T

SDN
(1 + (T

2)
This depends on the value of resistor R16 connected to V
S
. If the supply voltage is 2.0 to 3.5 V, Pin 16 can
be directly connected to V
S
. For V
S
= 5 V, R16 should be 3.9 k .
