The LTC1668CG#PBF is a 16-bit 50MSPS differential current output D/A Converter 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. 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. Operating from ±5V supplies, the LTC1668 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 -1 to 1V output compliance of the LTC1668 allows the outputs to be connected directly to external resistors to produce a differential output voltage without degrading the converter"s linearity. Alternatively, the outputs can be connected to the summing junction of a high speed operational amplifier or to a transformer.
● Pin compatible 12-bit, 14-bit and 16-bit devices

● 5pV-s Glitch impulse
● Differential current outputs
● 20ns Settling time
● Low power (180mW from ±5V supplies)
● TTL/CMOS (3.3 or 5V) inputs
