The HI5630 is a monolithic, triple 8-bit, 80MSPS analog-to-digital converter fabricated in an advanced CMOS process. It is designed for digitizing RGB graphics from work stations and personal computers. The HI5630 reaches a new level of multi-channel integration. The fully pipeline architecture and an innovative input stage enable the HI5630 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 drive all 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).
