FEATURES  
DESCRIPTION  
The LTC®1590 is a dual, serial input 12-bit multiplying  
digital-to-analog converter (DAC). It includes two current  
output multiplying CMOS DACs and an easy SPI compat-  
ible serial interface with daisy-chain output. An asynchro-  
nous CLR pin sets both DACs to zero scale.  
DNL and INL Over Temperature: ±0.5LSB Max  
Gain Error:  
±
1LSB Max  
Low Supply Current: 10  
µA Max  
4-Quadrant Multiplication  
Power-On Reset  
Asynchronous Clear Input  
Daisy-Chain 3-Wire Serial Interface  
16-Pin Narrow SUO and PDIP Packages  
Excellent accuracy, stability and versatility are combined  
with the smallest package available for a dual 12-bit  
multiplying DAC.  
Parts are available in 16-pin PDIP and narrow SO pack-  
ages and are specified over the commercial and industrial  
temperature ranges.
