Description
54, 56, 58
REFCAPA, REFCAPB,
REFCAPC
Decoupling capacitors are connected to these pins. This decouples the reference buffer for each
ADC pair. Each REFCAP pin should be decoupled to AGND using 10 F and 100 nF capacitors.
33, 36, 39,
42, 45, 48
V1 to V6
Analog Input 1 to 6. These are six single-ended analog inputs. In hardware mode, the analog input
range on these channels is determined by the RANGE pin. In software mode, it is determined by
Bit RNGC to Bit RNGA of the control register (see Table 10).
32, 37, 38, 43,
44, 49, 52, 53,
55, 57, 59
AGND
Analog Ground. Ground reference point for all analog circuitry on the AD7656/AD7657/AD7658.
All analog input signals and any external reference signal should be referred to this AGND voltage.
All 11 of these AGND pins should be connected to the AGND plane of a system. The AGND and
DGND voltages should ideally be at the same potential and must not be more than 0.3 V apart,
even on a transient basis.
26
DVCC
Digital Power, 4.75 V to 5.25 V. The DVCC and AVCC voltages should ideally be at the same potential
and must not be more than 0.3 V apart, even on a transient basis. This supply should be decoupled
to DGND, and 10 F and 100 nF decoupling capacitors should be placed on the DVCC pin.
9
VDRIVE
Logic Power Supply Input. The voltage supplied at this pin determines the operating voltage of
the interface. Nominally at the same supply as the supply of the host interface. This pin should be
decoupled to DGND, and 10 F and 100 nF decoupling capacitors should be placed on the VDRIVE pin.
8, 25
DGND
Digital Ground. This is the ground reference point for all digital circuitry on the AD7656/AD7657/AD7658.
Both DGND pins should connect to the DGND plane of a system. The DGND and AGND voltages should
ideally be at the same potential and must not be more than 0.3 V apart, even on a transient basis.
34, 35, 40,
41, 46, 47,
50, 60
AVCC
Analog Supply Voltage, 4.75 V to 5.25 V. This is the supply voltage for the ADC cores. The AVCC and
DVCC voltages should ideally be at the same potential and must not be more than 0.3 V apart, even
on a transient basis. These supply pins should be decoupled to AGND, and 10 F and 100 nF
decoupling capacitors should be placed on the AVCC pins.
23, 22, 21
CONVST A,
CONVST B, CONVST C
Conversion Start Input A, B, C. These logic inputs are used to initiate conversions on the ADC pairs.
CONVST A is used to initiate simultaneous conversions on V1 and V2. CONVST B is used to initiate
simultaneous conversions on V3 and V4. CONVST C is used to initiate simultaneous conversions on
V5 and V6. When CONVSTx switches from low to high, the track-and-hold switch on the selected
ADC pair switches from track to hold and the conversion is initiated. These inputs can also be used
to place the ADC pairs into partial power-down mode.
