Intersil HI5905EVAL2 Operation & User’s Manual

Description The HI5905EVAL2 evaluation board allows the circuit designer to evaluate the performance of the Intersil HI5905 monolithic 14-bit, 5MSPS analog-to-digital converter (ADC). As shown in the Evaluation Board Functional Block Diagram, the evaluation board includes sample clock generation circ ...

The HI5905 has an internal reference voltage generator, therefore no external reference voltage is required. The eval board, however, offers the ability to use the internal or an external reference. VROUT must be connected to VRIN when using the internal reference. Internal to the converter, two reference voltages of 1 ...

the evaluation board and should be driven by clean linear regulated supplies. The external power supplies are hooked up with the twisted pair wires soldered to the plated through holes marked +5VAIN, +5VAIN1, -5VAIN, +5VDIN, +5VD1IN, +5VD2IN, -5VDIN, AGND and DGND near the analog prototyping area. ...

available through two connectors contained on the evaluation board. The line buffering provided by the data output latches allows for driving long leads or analyzer inputs. These data latches are not necessary for the digital output data if the load presented to the converter does not exceed the d ...
