ISL5827

Dual 12-bit, +3.3V, 260+MSPS, High Speed

D/A Converter

The ISL5827 is a dual 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 and ISL5x27 families

of high speed converters, which include 8-, 10-, 12-, and

14-bit devices.
