Manufactured in ULTRAFILM technology, these resistor
network chips have a high level of integration, wide ohmic
value range, very low temperature coefficient 10 ppm/°C
which are unequaled on the market today. Laser trimming
can provide excellent precision down to 0.1 % abs 0.01 %
ratio.
FEATURES
•High precision tolerances down to 0.01 % Ratio
•Very low temperature coefficient: 10 ppm/°C abs.,
2 ppm/°C ratio
•Excellent stability < 300 ppm, 2000 h at Pn at
+ 70 °C
•Wirebondable
•Compliant to RoHS directive 2002/95/EC
