ANALOG DEVICES LTC1667IG#PBF Digital to Analogue Converter, Rail-to-Rail Output, 14 bit, 50 MSPS, Serial, ± 4.75V to ± 5.25V

LTC1667IG#PBF is a 14bit, differential current output DAC implemented on a high-performance BiCMOS process with laser-trimmed, thin-film resistors. The combination of a novel current steering architecture and a high-performance process produces DACs with exceptional AC and DC performance. Operating from ±5V supplies, this device can be configured to provide full-scale output currents up to 10mA. The differential current outputs of the DACs allow single-ended or true differential operation. The -1V to 1V output compliance of the device allows the outputs to be connected directly to external resistors to produce a differential output voltage without degrading the converter�s linearity. Applications include cellular base stations, multicarrier base stations, wireless communication, direct digital synthesis (DDS), xDSL modems, arbitrary waveform generation, automated test equipment, and instrumentation.
