HI5805

FN3984.7

12-Bit, 5MSPS A/D Converter

The HI5805 is a monolithic, 12-bit, Analog-to-Digital

Converter fabricated in Intersil’s HBC10 BiCMOS process. It

is designed for high speed, high resolution applications

where wide bandwidth and low power consumption are

essential.

The HI5805 is designed in a fully differential pipelined

architecture with a front end differential-in-differential-out

sample-and-hold (S/H). The HI5805 has excellent dynamic

performance while consuming 300mW power at 5MSPS.

The 100MHz full power input bandwidth is ideal for

communication systems and document scanner

applications. Data output latches are 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 3.0V to 5.0V supply.

NOTE: Intersil Pb-free products employ special Pb-free material sets;

molding compounds/die attach materials and 100% matte tin plate

termination finish, which are RoHS compliant and compatible with

both SnPb and Pb-free soldering operations. Intersil Pb-free products

are MSL classified at Pb-free peak reflow temperatures that meet or

exceed the Pb-free requirements of IPC/JEDEC J STD-020.
