DESCRIPTION

The HC2700 Series are Precision V oltage References that use Thin Film Hybrid technology to achieve extremely accurate, low temperature coefficient, 10 volt reference sources. Nichrome Thin Film resistors on ceramic provide excellent characteristics: low absolute and tracking temperature coefficients, trimmable to high accu- racy and superior long term stability. K ey specifications for the HC2700 Series include: untrimmed initial accuracy to 2.5 mV (0.025% ) max- imum, drifts over temperature to 3 ppm C maximum. and ± 5 mA drive minimum over the full operating temperature range. Line and load regulation are 300 µV /V and 50 µV /mA maximum and long term stability is also excellent, typically 100 ppm for 1000 hours at 25 C. The HC2700 Series includes internal power supply filter capacitors to insure continuous low noise operation. Three basic versions are available, the HC2700 for +10 volt applications, the HC2701 for -10 volt applications and the HC2702 for applications requir- ing both +10 volt and'-10 volt sources which track over temperature. The HC2700 Series is packaged in standard 14 pin Dual-in-Line packages and 28 pin LCC. M odels are available fully compliant to M IL-STD-883 for military and aerospace applications.
