Actual Size
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.
