ISL5827

Data Sheet

May 2004

FN6083

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.

Features

鈥?Low Power . . . . . 233mW with 20mA Output at 130MSPS

鈥?Adjustable Full Scale Output Current . . . . . 2mA to 20mA

鈥?Guaranteed Gain Matching < 0.14dB

鈥?+3.3V Power Supply

鈥?3V LVCMOS Compatible Inputs

鈥?Excellent Spurious Free Dynamic Range
