Unipolar Mode: 0V to 5V, 0V to 10V  
Bipolar Mode: ±5V, ±10V, ±2.5V, 2.5V to 7.5V  
1LSB Max DNL and INL Over the Industrial  
Temperature Range  
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.  
Glitch Impulse < 2nV-s  
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.
