Description
25, 26, 28
CAP2
AO
Connect all three CAP2 pins together and decouple them with the shortest trace possible to a single
10 μF, low ESR, low ESL capacitor. The other side of the capacitor must be placed close to Pin 27 (GND).
27
GND
P
Ground. Return path for the 10 μF capacitor connected to Pin 25, Pin 26, and Pin 28.
29, 30, 32
REF
AI/O
Buffered Reference Voltage. When using the internal reference or the 1.2 V external reference (REFIN
input), the 4.096 V system reference is produced at this pin. When using an external reference, such
as the ADR434 or the ADR444, the internal reference buffer must be disabled. In either case, connect
all three REF pins together and decouple them with the shortest trace possible to a single 10 μF, low
ESR, low ESL capacitor. The other side of the capacitor must be placed close to Pin 31 (GND).
31
GND
P
Ground. Return path for the 10 μF capacitor connected to Pin 29, Pin 30, and Pin 32.
EP
Exposed Pad
The exposed pad is located on the underside of the package. Connect the exposed pad to the
ground plane of the PCB using multiple vias. See the Exposed Paddle section for more information.
1 AI = analog input; AI/O = bidirectional analog; AO = analog output; DI = digital input; DO = digital output; P = power.
