MAX1171 Datasheet, PDF (11/12 Pages) Maxim Integrated Products – 12-Bit, 20Msps, TTL-Output ADC

12-Bit, 20Msps, TTL-Output ADC
Overrange Output
The overrange output (D12) is an indication that the an-
alog input signal has exceeded the full-scale input volt-
age by 1LSB. When this condition occurs, the outputs
will switch to logic 1s. All other data outputs are unaf-
fected by this operation. This feature makes it possible
to include the MAX1171 in higher resolution systems.
Evaluation Board
The MAX1170 evaluation kit (EV kit) is available to aid
designers in demonstrating the full performance of the
MAX1171 (or of the MAX1170/MAX1172). This board
includes a reference circuit, clock driver circuit, output
data latches, and on-board reconstruction of the digital
data. A separate EV kit manual describing the opera-
tion of this board is available. Contact the factory for
price and availability.
