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.

• TTL/CMOS(3V) Digital Inputs CMOS Digital Outputs  
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.  
• Offset Binary or Two’s Complement Digital Data Output

• Dual 10-Bit A/D Converters on a Monolithic Chip  
• Pin Compatible Upgrade to AD9288  
The ISL5740 is offered in 20MSPS, 40MSPS and 60MSPS  
sampling rates.
