Low Glitch Multiplying DACs
DESCRIPTIO
The LTC
14-bit and 16-bit multiplying current output DACs that oper-
ate from a single 5V supply. INL and DNL are accurate to 1LSB
over the industrial temperature range in both 2- and 4-
quadrant multiplying modes. True 16-bit 4-quadrant multi-
plication is achieved with on-chip 4-quadrant multiplication
resistors.
These DACs include an internal deglitcher circuit that reduces
the glitch impulse to less than 2nV-s (typ). The asynchronous
CLR pin resets the LTC1591/LTC1597 to zero scale and
LTC1591-1/LTC1597-1 to midscale.
The LTC1591/LTC1597 are available in 28-pin SSOP and
PDIP packages and are specified over the industrial tempera-
ture range.
For serial interface 16-bit current output DACs refer to the
LTC1595/LTC1596 data sheet.
