3V Dual 10-Bit, 20/40/60MSPS A/D Converter with Internal Voltage Reference

The ISL5740 is a monolithic, dual 10-bit analog-to-digital converter fabricated in an advanced CMOS process. It is designed for high speed applications where integration, bandwidth and accuracy are essential. The ISL5740 features a 9-stage pipeline architecture. The fully pipelined architecture and an innovative input stage enable the ISL5740 to accept a variety of input configurations, singleended or fully differential. Only one external clock is necessary to drive both converters and an internal band-gap voltage reference is provided. This allows the system designer to realize an increased level of system integration resulting in decreased cost and power dissipation.
