DESCRIPTIO
The LTC®1588/LTC1589/LTC1592 are serial input 12-/14-
/16-bit multiplying current output DACs that operates
from a single 5V supply. These SoftSpanTM DACs can be
software-programmed for either unipolar or bipolar mode
through a 3-wire SPI interface. In either mode, the voltage
output range can also be software-programmed. Two
output ranges in unipolar mode and four output ranges in
bipolar mode are available.
INL and DNL are accurate to 1LSB over the industrial
temperature range in both unipolar and bipolar modes.
True 16-bit 4-quadrant multiplication is achieved with
on-chip four quadrant multiplication resistors. The
LTC1588/LTC1589/LTC1592 are available in a 16-lead
SSOP package.
These devices include an internal deglitcher circuit that
reduces the glitch impulse to less than 2nV-s (typ).
The asynchronous clear pin resets the LTC1588/LTC1589/
LTC1592 to 0V in unipolar or bipolar mode.
