Notes
1. The typical value of
I
INT
is set by the value of
Iprop(1)
and the programmed value of
K
.
2. The current output
I
INT
is specified between 1mA and 10mA.
Notes
1. The typical value of
I
COMP
(0)
is set by the fractional-N accumulator value Acc and the current
Irsc
set by the external
resistor RSC, where
Ico
=
Irsc
/128.
Irsc
is typically 12.8μA.
2. The typical value of
I
COMP
(1)
is set by the value of
I
COMP
(0)
and the programmed value of
L.
3. The current output
I
COMP
is specified up to 12μA.
4. The typical value of I
COMP
2
is set by the value of I
COMP
(1)
and the programmed value of
K.
5. The current output I
COMP
2
is specified up to 180μA.
