H C2700 LCC Series +10V, Ð 1 0V, and ± 10V Leadless Chip Carrier Precision V oltage References JED EC- Compatible FEA TURES • 2700 Type Reference in Standard LCC Packages • JEDEC-Compatible 28 Pin LCC Style Package • +10, –10, + / –10V olt Ranges • New K elvin Sense Connections • Initial A ccuracy to 2.5mV • Temp. Coefficients to 3ppm • Short Circuit Protected • Industrial and M il Temp. Ranges • Surface M ount and RefIow-Solderable DESCRIPTION The new HC2700LCC Series packages the HC2700, HC2701 and HC2702 in a 28 pin JEDEC compatible leadless chip carrier. The HC2700LCC series combines the standard features of the HC2700 series in LCC packages with a new flexible pin out. This new pin out offers, uncommitted feedback resistors and zener ground points, which allows for K elvin sensing at the output voltage and reference ground. This provides improved performance at greater distances from the HC2700LCC. In addition, feedback resistors and a resistor divider has been included in the LCC substrate design, allowing any unique reference voltage to be trimmed in accordance with your specification.
