Input
Device enable control. Low level input disables the reference output
and device enters shutdown mode. Device can be enabled by driving
voltage > 1.6V or leaving the EN pin floating.
VIN
2
Power
Input supply voltage connection. Connect a minimum 0.1-μF
decoupling capacitor to ground for the best performance.
NIC
3
No Connect
Not internally connected. Pin can be left floating or to a known
potential.
GND
4
Ground
Ground connection.
NR
5
Output
Noise reduction pin. Connect a decoupling capacitor to ground for
improved noise performance. The pin can be left floating.
VREF
6
Output
Reference voltage output. Connect a capacitor between 1 μF to 100
μF to ground for best performance.
DNC
