External Compensation. Connect a 4.7μF capacitor to ground as close as possible to the pin to
bypass the internal biasing circuitry.
15 EXT_C3
External Compensation. Connect a 4.7μF capacitor to ground as close as possible to the pin to
bypass the internal biasing circuitry.

REF
5V Reference Supply. Connect to a low-noise power supply. Bypass to GND with a 0.1μF capacitor
as close as possible to the pins. Note that noise performance of the device is dependent on the
noise contribution from the supply to V
REF
. Use a low-noise supply for V
REF
. V
CC
and V
REF
can be
connected together to share the same supply voltage if the supply for V
CC
exhibits low noise.
