SENSE (Pin 1): Reference Mode Select and External
Reference Input. Tie SENSE to VDD to select the internal
2.5V bandgap reference. An external reference of 2.5V or
1.25V may be used; both reference values will set a full
scale ADC range of 2.25V (PGA = 0).
VCM(Pin2):1.25VOutput.Optimumvoltageforinputcom-
mon mode. Must be bypassed to ground with a minimum
of 2.2μF. Ceramic chip capacitors are recommended.
VDD (Pins 3, 4, 12, 13, 14): 3.3V Analog Supply Pin.
Bypass to GND with 0.1μF ceramic chip capacitors.
GND (Pins 5, 8, 11, 15, 48): ADC Power Ground.
AIN+ (Pin 6): Positive Differential Analog Input.
AIN– (Pin 7): Negative Differential Analog Input.
ENC+ (Pin 9): Positive Differential Encode Input. The
sampled analog input is held on the rising edge of ENC+.
Internally biased to 1.6V through a 6.2k resistor. Output
data can be latched on the rising edge of ENC+.
ENC– (Pin 10): Negative Differential Encode Input. The
sampled analog input is held on the falling edge of ENC–.
Internally biased to 1.6V through a 6.2k resistor. Bypass to
ground with a 0.1μF capacitor for a single-ended Encode
signal.
SHDN (Pin 16): Power Shutdown Pin. SHDN = low results
in normal operation. SHDN = high results in powered
down analog circuitry and the digital outputs are placed
in a high impedance state.
DITH (Pin 17): Internal Dither Enable Pin. DITH = low
disables internal dither. DITH = high enables internal dither.
Refer to Internal Dither section of this data sheet for details
on dither operation.
NC (Pins 18, 19): No Connect.
D0-D13 (Pins 20-22, 26-28, 32-35 and 39-42): Digital
Outputs. D13 is the MSB.
OGND (Pins 23, 31 and 38): Output Driver Ground.
OVDD (Pins 24, 25, 36, 37): Positive Supply for the Output
Drivers. Bypass to ground with 0.1μF capacitor.
CLKOUT– (Pin 29): Data Valid Output. CLKOUT– will toggle
at the sample rate. Latch the data on the falling edge of
CLKOUT–.
CLKOUT+ (Pin 30): Inverted Data Valid Output. CLKOUT+
will toggle at the sample rate. Latch the data on the rising
edge of CLKOUT+.
