Product Overview

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
  • High spectral purity (87dB SFDR at 1MHz fOUT)
  • 5pV-s Glitch impulse
  • Differential current outputs
  • 20ns Settling time
  • Low power (180mW from ±5V supplies)
  • TTL/CMOS (3.3 or 5V) inputs
