ADVANCE INFORMATION  
3V Dual 8-Bit, 20/40/60MSPS A/D  
Features

The ISL5640 is a monolithic, dual 8-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 ISL5640  
features a 9-stage pipeline architecture. The fully pipelined  
architecture and an innovative input stage enable the  
ISL5640 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.

• Single Supply Voltage Operation . . . . . . . . . . . . . . . +3.0V  
• Offset Binary or Two’s Complement Output Format  
• Dual 8-Bit A/D Converters on a Monolithic Chip  
• Pin Compatible Upgrade to AD9288  
The ISL5640 has excellent dynamic performance while  
consuming less than 100mW power at 40MSPS. 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 ISL5640 is offered in 20MSPS, 30MSPS, 40MSPS and  
60MSPS sampling rates.
