Linear Technology LTC1667

The LTC1668 is the first 16-bit DAC in the marketplace to exhibit an SFDR (spurious free dynamic range) of 87dB for an output signal frequency of 1MHz. The differential current outputs of the DACs allow single-ended or true differential operation. The –1V to 1V output compliance of the LTC1666/ LTC1667/LTC1668 allows the outputs to be connected directly to external resistors to produce a differential output voltage without degrading the converter’s linearity.

The combination of a novel currentsteering architecture and a high performance process produces DACs with exceptional AC and DC performance. Operating from ±5V supplies, the LTC1666/LTC1667/ LTC1668 can be configured to provide full-scale output currents up to 10mA.
