ISL5957

14-Bit, +3.3V, 260+MSPS, High Speed D/A

Converter

The ISL5957 is a 14-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.

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.
