IRC's precision voltage divider delivers accuracy for military systems
Mar 29, 2005
Providing military and aerospace analog design engineers with a precision two-element resistor network in a 1206 chip package, TT Electronics IRC Advanced Film Division has developed a military voltage divider that provides two matched resistors with precision absolute and ratio tolerances (Â±0.05%/Â±0.01%) on a single chip.
Designated the D1206 Series, the ceramic chip is said to exhibit better TCR tracking, higher accuracy, and significant board space savings compared to designs using two discrete resistors.
According to Jerry Seams, applications engineering manager for IRC's Advanced Film Division, the D1206 Series dividers are ideal for precision analog circuit designs for military and aerospace applications, especially gain control circuits in op amps and as a reference voltage for military power supplies. "The tantalum nitride resistive element provides long term stability over time and temperature, and is impervious to the corrosion problems often experienced with other types of resistive materials under biased humidity, as well as other harsh environmental conditions."
Typical pricing for the precision voltage divider is $1.00 in quantities of a least 1,000 pieces, with lead times of 8-10 weeks.
