3.3V Dual 8-Bit, 40MSPS A/D Converter  
with Internal Reference and Digital Clamp  
Features  
• Sampling Rate . . . . . . . . . . . . . . . . . . . . . . . . . . .40MSPS  
The HI2325 is a monolithic, dual 8-bit, 40MSPS 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 HI2325 features  
a 2-stage parallel architecture. Only one external clock is  
necessary to drive both converters and an internal voltage  
reference is provided allowing the system designer to realize  
an increased level of system integration resulting in  
decreased cost and power dissipation.  
• 6.5 Bits at f = 1MHz  
IN  
• Low Power at 40MSPS. . . . . . . . . . . . . . . . . . . . . 100mW  
• Power Down Mode . . . . . . . . . . . . . . . . . . . . . . . . . . 8mW  
• Wide Full Power Input Bandwidth. . . . . . . . . . . . . 250MHz  
• Excellent Channel-to-Channel Isolation . . . . . . . . . >75dB  
• Internal Digital Clamp  
• Internal Voltage Reference  
The HI2325 has excellent dynamic performance while  
consuming less than 100mW power at 40MSPS. The A/D  
only requires a single +3.3V power supply and encode clock.  
Data output latches are provided which present valid data to  
the output bus with a latency of 2 clock cycles.  
• Single Supply Voltage Operation . . . . . . . . . . . . . . . +3.3V  
• TTL/CMOS Compatible Digital Inputs  
• CMOS Compatible Digital Outputs. . . . . . . . . . . . . . . 3.3V  
• Offset Binary or 2’s Complement Output Format  
• Dual 8-Bit A/D Converters on a Monolithic Chip
