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.
