and beyond which the serviceability of the circuit may be impaired. Functional

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

s

CONVERT, CONVERT (Pins 23, 24) : “Differential Convert Command” initiates a new conversion cycle on

the rising edge of CONVERT.

s

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.

s

(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.

s

(MSB) D1 (Pin 6): Inverted version of the MSB, used for 2’s Complement coding.

Analog Input

s

s

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

s

s

D.N.C (Pins 4, 5, 19, 20, 28, 29): Do Not Connect.

s

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.

s

OFFSET REFERENCE (Pin 37): OFFSET REFERENCE tracks gain adjustments and is used for offset

voltage adjustment.
