概要
The ISL5961 is a 14-bit, 130/210+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 ISL5x61 family of high-speed converters, which include 10, 12 and 14-bit devices.

14-Bit, +3.3V, 210/130MSPS High-Speed D/A Converter Evaluation Board
The ISL5961EVAL1 evaluation board provides a quick and easy method for evaluating the ISL5961 14-bit, 130/210MSPS high-speed digital-to-analog (D/A) converter. The ISL5961EVAL1 is populated with an SOIC package. The board is configured so that the converter outputs differential current into a transformer circuit to form an output voltage. The amount of current out of the DAC is determined by an external resistor and either an internal or external reference voltage.
