Rev 3.00
October 7, 2015 12-bit, +3.3V, 260+MSPS, High Speed D/A Converter
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. Features This device complements the ISL5x57 family of high speed
converters, which include 10, 12, and 14-bit devices. 3V LVCMOS compatible inputs Low power 103mW with 20mA output at 130MSPS Adjustable full scale output current . 2mA to 20mA +3.3V power supply Excellent spurious free dynamic range
(73dBc to Nyquist, f S = 130MSPS, fOUT = 10MHz) Applications Cellular Infrastructure -single or multicarrier: IS-136, IS-95,
GSM, EDGE, CDMA2000, WCDMA, TDS-CDMA UMTS adjacent channel power = 70dB at 19.2MHz BWA infrastructure Medical/test instrumentation Pin compatible, 3.3V, lower power replacement for the
