LINEAR TECHNOLOGY  LTC1666CG#PBF  数模转换器, 12 bit, 50 MSPS, 并行, 4.75V 至 5.25V, SSOP, 28 引脚

The is a 12-bit differential current output Digital-to-analog Converter 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 DAC with exceptional AC and DC performance. Operating from ±5V supplies, the LTC1666 can be configured to provide full-scale output currents up to 10mA. The differential current outputs of the DAC allow single-ended or true differential operation. The -1 to 1V output compliance of the LTC1666 allows the outputs to be connected directly to external resistors to produce a differential output voltage without degrading the converter linearity. Alternatively, the outputs can be connected to the summing junction of a high speed operational amplifier or to a transformer.
