External load should not change during conversion. 5/ Bipolar Mode 6/ The AD1672 includes an onboard +2.5 V reference. The reference input pin (REF IN) can be connected to reference output pin (REF OUT) or a standard external +2.5 V reference can be selected to meet specific system requirements. The reference input voltage can be held with the use of a capacitor. To prevent the AD1672’s onboard reference from oscillating when not connected to REF IN, REF OUT must be connected to +5 VVCC. It is possible to connect REF OUT to +5 V due to its output circuit implementation which shuts down the reference ASD0010965 Rev.
