Overview

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.
