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 con鏗乬urations, 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.
