1 / 12 page TM 3-1 PRELIMINARY ISL5740 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, single- ended 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. The ISL5740 has excellent dynamic performance while consuming less than 280mW power at 60MSPS. The A/D only requires a single +3.0V power supply. Data output latches are provided which present valid data to the output bus with a latency of 5 clock cycles. The ISL5740 is offered in 20MSPS, 40MSPS and 60MSPS sampling rates.
