Data Sheet October 1999
Triple 8-Bit, 80MSPS A/D Converter with
Internal Voltage Reference
The HI5630 is a monolithic, triple 8-bit, 80MSPS
analog-to-digital converter fabricated in an advanced CMOS
process. It is designedfor digitizing RGB graphicsfromwork
stations and personal computers. The HI5630 reaches a
new level of multi-channel integration. The fully pipeline
architecture andaninnovativeinput stageenable theHI5630
to accept a variety of single-ended or fully differential input
configurations which present valid data to the output bus
with a latency of 5 clock cycles. Only one external clock is
necessary to driveall three converters with a clock out signal
provided. An internal band-gap voltage reference is also
provided allowing the system designer to realize an
increased level of system integration resulting in decreased
cost and power dissipation.
The HI5630 can be bench tested using a complete ADC
evaluation board with clock drivers, ADC, latches and a
reconstruct DAC. In addition, complete LCD monitor
reference designs are available for immediate volume
production (contact factory).
