Intersil Corporation HI5808 Datasheet
HI5808
Data Sheet February 1999 File Number 4233.4
12-Bit, 10 MSPS A/D Converter
The HI5808 is a monolithic, 12-bit, Analog-to-Digital
Converter fabricated in Intersil’sHBC10BiCMOS process.It
is designed for high speed, high resolution applications
where wide bandwidth and low power consumption are
essential.
The HI5808 is designed in a fully differential pipelined
architecture with a front end differential-in-differential-out
sample-and-hold (S/H). The HI5808 has e xcellent dynamic
performance while consuming 325mW power at 10 MSPS.
The 100MHz full power input bandwidth is ideal for
communication systems and document scanner
applications. Dataoutputlatchesare provided which present
valid data to the output bus with a latency of 3 clock cycles.
The digital outputs have a separate supply pin which can be
powered from a 3V to 5V supply.
