INL and DNL are accurate to 1LSB over the industrial temperature range in both 2- and 4-quadrant multiplying modes. True 16bit 4-quadrant multiplication is achieved with on-chip 4-quadrant multiplication resistors. These DACs include an internal deglitcher circuit that reduces the glitch impulse to less than 2n V-s (typ). The asynchronous CLR pin resets the LTC1591/LTC1597 to zero scale and LTC1591-1/LTC1597-1 to mid-scale. The LTC1591/LTC1597 are available in the 28-pin SSOP package and are specified over the industrial temperature range. For serial interface 16-bit current output DACs refer to the LTC1595/LTC1596 data sheet.
