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.
