14-Bit, 5 MSPS A/D Converter
Features
The HI5905 is a monolithic, 14-bit, 5 MSPS Analog-to-
Digital Converter fabricated in an advanced BiCMOS
process. It is designed for high speed, high resolution
applications where wide bandwidth, low power
consumption and excellent SINAD performance are
essential. With a 100MHz full power input bandwidth and
high frequency accuracy, the converter is ideal for many
types of communication systems employing digital IF
architectures.

The HI5905 is designed in a fully differential pipelined
architecture with a front end differential-in-differential-out
sample-and-hold amplifier (S/H). The HI5905 has excellent
dynamic performance while consuming 350mW power at 5
MSPS.
• TTL Compatible Clock Input
• CMOS Compatible Digital Data Outputs
Applications
