I
1
Analog bias current input - adjusts polarization current versus Fs.
I/O
2
Top Reference Voltage - may be used as a voltage generator output or used as an
input to adjust the input dynamic range (VIN-VINB=2x(VREFP-VREFM)).
I
3
Bottom Reference Voltage. Usually connected to GND (see AN p12 for details)
I 4, 6, 8, 10, 48 Analog ground.
I
5
Positive Analog input.
I
7
Negative Analog Input.
Internal Common Mode - may be used as a voltage generator output for input sig-
I/O
9
nal common mode or used as an input to force the internal common mode (see AN
p12 for more details).
I 11, 12, 46, 47 Analog Power Supply (2.5V).
I
13, 14 Digital Power Supply (2.5V) (Clock).
I 15, 17,19 Digital Ground (Clock).
I
16
CMOS Clock Input.
NA 18, 42 Non Connected Pin.
I
20
Digital Ground (Internal Buffer).
I
21,40 Digital Ground (External Buffer).
I
22, 39 Digital Power Supply (External Buffer, 2.5V/3.3V).
O
23
Over Range Indicator, if D0-D13=’1’ or ‘0’, OR=’1’.
O
24-37
Data CMOS Outputs (2.5V/3.3V).
O
38
Data Ready Signal (2.5V/3.3V).
I
41
Digital Power Supply (Internal Buffers 2.5V).
REFMODE=’VIL’, internal references active.
I
43
REFMODE=‘VIH’, external references must be applied.
I
44
Output Enable Input. If OEB=’VIH’ then D0-D13 in ‘High Z’ state.
I
45
Data Format Select Input - If DFSB=’VIH’ then D13 is standard binary output cod-
ing; if DFSB=’VIL’ then D13 is two’s complemented.
