Description
Reference Input (REFIN)/Reference Output (REFOUT). The on-chip reference
of 2.5 V is available on this pin for external use if the REF SELECT pin is set to
logic high. Alternatively, the internal reference can be disabled by setting
the REF SELECT pin to
applied to this input (see the Internal/External Reference section).
Decoupling is required on this pin for both the internal and external
reference options. A 10 μF capacitor should be applied from this pin to
ground close to the REFGND pins.
Reference Ground Pins. These pins should be connected to AGND.
Reference Buffer Output Force/Sense Pins. These pins must be connected
together and decoupled to AGND using a low ESR, 10 μF ceramic capacitor.
The voltage on these pins is typically 4.5 V.
Analog Input. This pin is a single-ended analog input. The analog input
range of this channel is determined by the RANGE pin.
Analog Input Ground Pins. These pins correspond to Analog Input Pin V1
and Analog Input Pin V2. All analog input AGND pins should connect to
the AGND plane of a system.
Analog Input. This pin is a single-ended analog input. The analog input
range of this channel is determined by the RANGE pin.
Analog Input 3. For the AD7606-4, this is an AGND pin.
Analog Input Ground Pin. For the AD7606-4, this is an AGND pin.
Analog Input 4. For the AD7606-6 and the AD7606-4, this is an AGND pin.
Analog Input Ground Pin. For the AD7606-6 and AD7606-4, this is an
AGND pin.
Analog Inputs. These pins are single-ended analog inputs. The analog
input range of these channels is determined by the RANGE pin.
