DATASHEET
FN4129
Rev 5.00
July 2004
The HI5746 is a monolithic, 10-bit, analog-to-digital
converter fabricated in a CMOS process. It is designed for
high speed applications where wide bandwidth and low
power consumption are essential. Its 40MSPS speed is
made possible by a fully differential pipelined architecture
with an internal sample and hold.
The HI5746 has excellent dynamic performance while
consuming only 225mW power at 40MSPS. Data output
latches are provided which present valid data to the output
bus with a latency of 7 clock cycles. It is pin-for-pin
functionally compatible with the HI5702 and the HI5703.
For internal voltage reference, please refer to the HI5767
data sheet.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is 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-020B.
