RB2:
Connection for a resistor that sets the
channel 2 output source current.
Use a resistor in the range 750
1.5 k .
RB1:
Connection for a resistor that sets the
channel 1 output source current.
Use a resistor in the range 750
1.5 k .
OUT1:
Push-pull output.
The absolute maximum rating for the
output source current is 50 mA.
Connecting the external resistor to RB1
terminal allows this circuit to provide
an output source current with excellent
line regulation and minimal sample-to-
sample variations.
OUT2:
Push-pull output.
The absolute maximum rating for the
output source current is 50 mA.
Connecting the external resistor to RB2
terminal allows this circuit to provide
an output source current with excellent
line regulation and minimal sample-to-
sample variations.
GND:
Ground.
