Asynchronous Clear to 0V for All Ranges

The LTC

/16-bit multiplying current output DACs that operates

from a single 5V supply. These SoftSpan

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.
