operability under any of these conditions is not necessarily implied. Exposure to
maximum ratings for extended periods may affect device reliability.

ECL-Level Digital Inputs
I
CONVERT, CONVERT
(Pins 23, 24) : “Differential Convert Command” initiates a new conversion cycle on
the rising edge of CONVERT.
I
DATA INV (Pin 25): DATA INVERT is an active HIGH (grounded) ECL input which causes the data outputs
[D1 to D12] to be inverted. In normal operation, DATA INV is left floating or tied to ECL logic LOW.
ECL-Level Digital Outputs (Note: all ECL digital outputs have internal series resistances such that Z
out
= 50
±3
)
I
(MSB) D1-D12 (Pins 7 to 18): Digital Data Outputs. D1 is the MSB; D12 is the LSB. In their normal state,
the digital outputs offer Offset Binary output coding.
I
(MSB) D1
(Pin 6): Inverted version of the MSB, used for 2’s Complement coding.
Analog Input
I
V
IN
(Pin 39): Analog input with a 2.0V
pp
input range from +1.00V to -1.00V.
I
GAIN ADJUST
(Pin 33): The GAIN ADJUST has a +4V to +1V input range and scales the analog input full-
scale range by -10% to +10% respectively. If unused, Gain Adjust should be left floating.
Miscellaneous
I
V
REF
(+2.5V) (Pin 35): V
REF
is a highly stable +2.500V voltage reference. (Recommended current drain
≤
2mA.)
I
D.N.C
(Pins 4, 5, 19, 20, 28, 29): Do Not Connect.
I
OFFSET ADJUST
(Pin 36): OFFSET ADJUST has a GROUND to OFFSET REFERENCE input range
and scales the analog input offset by ò0.1V. If unused, OFFSET ADJUST should be left floating.
I
OFFSET REFERENCE
(Pin 37): OFFSET REFERENCE tracks gain adjustments and is used for offset
voltage adjustment.
