PMC-softDAC-18M
Software Programmable 2 µSecond DACs 18 Channel 16 bit DAC with programmable outputs
The Linear LTC1588/LTC1589/LTC1592 are serial input 12-/14-/16-bit multiplying current output DACs operating from a single 5V supply, offering software-programmable uni-polar or bi-polar modes through a 3-wire SPI interface12. These SoftSpan DACs provide two uni-polar and four bi-polar output ranges, maintaining 1LSB accuracy over the industrial temperature range in both modes23. They achieve true 16-bit 4-quadrant multiplication using on-chip resistors and feature an internal deglitcher circuit that reduces glitch impulse to less than 2nV-s typically
