3.3V Dual 8-Bit, 40MSPS A/D Converter
with Internal Reference and Digital Clamp
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.
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.
