FEATURES  
DESCRIPTIO  
The LTC®1821 is a parallel input 16-bit multiplying voltage  
output DAC that operates from analog supply voltages of  
±5V up to ±15V. INL and DNL are accurate to 1LSB over the  
industrial temperature range in both unipolar 0V to 10V and  
bipolar±10Vmodes.Precise16-bitbipolar±10Voutputsare  
achieved with on-chip 4-quadrant multiplication resistors.  
The LTC1821 is available in a 36-lead SSOP package and is  
specified over the industrial temperature range.  
2µs Settling to 0.0015% for 10V Step  
1LSB Max DNL and INL Over Industrial  
Temperature Range  
On-Chip 4-Quadrant Resistors Allow Precise 0V to  
10V, 0V to –10V or ±10V Outputs  
Low Glitch Impulse: 2nV•s  
Low Noise: 13nV/Hz  
36-Lead SSOP Package  
Power-On Reset  
Thedeviceincludesaninternaldeglitchercircuitthatreduces  
the glitch impulse to less than 2nV•s (typ). The LTC1821  
settles to 1LBS in 2µs with a full-scale 10V step. The  
combinationoffast,precisesettlingandultralowglitchmake  
the LTC1821 ideal for precision industrial control applica-  
tions.  
Asynchronous Clear Pin

APPLICATIO S  
The asynchronous CLR pin resets the LTC1821 to zero scale  
and resets the LTC1821-1 to midscale.
