REF SELECT
Internal/External Reference Selection. Logic input. If this pin is tied to GND, the on-chip 2.5 V reference
is used as the reference source for both ADC A and ADC B. In addition, pins VREF, DCAPA, and DCAPB
must be tied to decoupling capacitors. If the REF SELECT pin is tied to a logic high, an external refer-
ence can be supplied to the AD7866 through the VREF pin, in which case decoupling capacitors are
required on DCAPA and DCAPB. However, if the VREF pin is tied to AGND while REF SELECT is tied to
a logic low, an individual external reference can be applied to both ADC A and ADC B through pins
DCAPA and DCAPB, respectively. See the Reference Configuration Options section.
2, 9
DCAPB, DCAPA
Decoupling capacitors are connected to these pins to decouple the reference buffer for each respective
ADC. The on-chip reference can be taken from these pins and applied externally to the rest of a system.
Depending on the polarity of the REF SELECT pin and the configuration of the VREF pin, these
pins can also be used to input a separate external reference to each ADC. The range of the external
reference is dependent on the analog input range selected. See the Reference Configuration
Options section.
3, 8
AGND
Analog Ground. Ground reference point for all analog circuitry on the AD7866. All analog input signals
and any external reference signal should be referred to this AGND voltage. Both of these pins should
connect to the AGND plane of a system. The AGND and DGND voltages ideally should be at the
same potential and must not be more than 0.3 V apart, even on a transient basis.
4, 5
VB2, VB1
Analog Inputs of ADC B. Single-ended analog input channels. The input range on each channel is 0 V
to VREF or a 2
VREF range depending on the polarity of the RANGE pin upon the falling edge of CS.
6, 7
VA2, VA1
Analog Inputs of ADC A. Single-ended analog input channels. The input range on each channel is 0 V
to VREF or a 2
VREF range depending on the polarity of the RANGE pin upon the falling edge of CS.
10
VREF
Reference Decoupling and External Reference Selection. This pin is connected to the internal reference
and requires a decoupling capacitor. The nominal reference voltage is 2.5 V, which appears at the pin;
however, if the internal reference is to be used externally in a system, it must be taken from either the
DCAPA or DCAPB pins. This pin is also used in conjunction with the REF SELECT pin when
applying an external reference to the AD7866. See the REF SELECT pin description.
