12-bit, +3.3V, 260+MSPS, High Speed D/A
Converter
The ISL5857 is a 12-bit, 260+MSPS (Mega Samples Per
Second), CMOS, high speed, low power, D/A (digital to
analog) converter, designed specifically for use in high
performance communication systems such as base
transceiver stations utilizing 2.5G or 3G cellular protocols.
This device complements the ISL5x57 family of high speed
converters, which include 10, 12, and 14-bit devices.
Ordering Information
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-020C.
