37, 93 V 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.
