DEMO MANUAL DC2795 LTC1660/ LTC1665/ LTC1664 2-Channel, 10-Bit, Micropower DACs DESCRIPTION Demonstration circuit 2795 features the LTC 1660/ of 5mA and reliably driving capacitive loads to 1000pF. LTC1665 and LTC1664. The 8-bit LTC1665 and 10-bit Sleep mode further reduces total supply current to 1A. LTC1660 integrate eight accurate, serially addressable Design files for this circuit board are available at digital-to-analog converters (DACs) in tiny 16-pin narrow DEMO MANUAL DC2795 ASSEMBLY OPTIONS ASSEMBLY TYPE PART NUMBER DAC CHANNELS BITS DC2795A-A LTC1660 8 10 DC2795A-B LTC1665 8 8 DC2795A-C LTC1664 4 10 QUICK START PROCEDURE 1.
