Function
CMOS Output; Out-of-Range Indicator. Logic HIGH indicates the analog input voltage was
outside the converter’s range for the current output data.
Data Format Select and Gain Mode Select. Connect externally to AV
data format and 1 V p-p analog input range. Connect externally to AGND for Offset Binary data
format and 1 V p-p analog input range. Connect externally to REF (Pin 4) for two’s complement
data format and 2 V p-p analog input range. Floating this pin will configure the device for Offset
Binary data format and a 2 V p-p analog input range.
Reference Mode Select Pin for the ADC. This pin is normally connected externally to AGND,
which enables the internal 1.25 V reference, and configures REF (Pin 4) as an analog reference
output pin. Connecting REFSENSE externally to AV
ures REF (Pin 4) as an external reference input. In this case, the user must drive REF with a clean
and accurate 1.25 V (± 5%) reference input.
Reference input or output as configured by REFSENSE (Pin 3). When configured as an output
(REFSENSE = AGND), the internal reference (nominally 1.25 V) is enabled and is available to
the user on this pin. When configured as an input (REFSENSE = AV
REF with a clean and accurate 1.25 V (± 5%) reference. This pin should be bypassed to AGND
with an external 0.1 µF capacitor, whether it is configured as an input or output.
Analog Ground
Analog Power Supply, Nominally 3 V
Positive terminal of the differential analog input for the ADC.
Negative terminal of the differential analog input for the ADC. This pin can be left open if
operating in single-ended mode, but it is preferable to match the impedance seen at the positive
terminal (see Driving the Analog Inputs).
Encode Clock for the ADC. The AD9214 samples the analog signal on the rising edge of ENCODE.
CMOS-compatible power-down mode select, Logic LOW for normal operation; Logic HIGH
for power-down mode (digital outputs in high impedance state). PWRDN has an internal
10 kΩ pull-down resistor to ground.
Digital Output Ground
Digital Output Driver Power Supply. Nominally 2.5 V to 3.6 V.
