HI5905
FN4259.4
14-Bit, 5MSPS A/D Converter
The HI5905 is a monolithic, 14-bit, 5MSPS 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
5MSPS.
Data output latches are provided which present valid data to
the output bus with a low data latency of 4 clock cycles.
