OVERRANGE OUTPUT

Data Out

The OVERRANGE OUTPUT (D12) is an indication that the

analog input signal has exceeded the full scale input voltage

by 1 LSB. When this condition occurs, the output will switch

to logic 1. All other data outputs are unaffected by this

operation. This feature makes it possible to include the

SPT7910 into higher resolution systems.

EVALUATION BOARD

The EB7910 Evaluation Board is available to aid designers in

demonstrating the full performance of the SPT7910. This

board includes a reference circuit, clock driver circuit, output

data latches and an on-board reconstruction of the digital

data. An application note (AN7910) describing the operation

of this board as well as information on the testing of the

SPT7910 is also available. Contact the factory for price and

availability.
