Temperature Range

from a single 5V supply. These SoftSpan^TMDACs 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.

16-Lead SSOP Package

Power-On Reset to 0V

Asynchronous Clear to 0V for All Ranges

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.

APPLICATIO S

■

Process Control and Industrial Automation

■

Precision Instrumentation

■

Direct Digital Waveform Generation

These devices include an internal deglitcher circuit that

reduces the glitch impulse to less than 2nV-s (typ).
