X90100

® X90100 Data Sheet February 2, 2005 FN8156.0 NV Electronically Programmable Capacitor The Intersil X90100 is a non-volatile electronically programmable capacitor. The device is programmed through a simple digital interface. After programming, the chosen setting for the device is retained by internal EEPROM storage whether or not DC power is maintained. There are 32 programmable capacitance values selectable, ranging from 7.5pF to 14.5pF in 0.23pF increments, in single-ended mode. The dielectric is highly stable, and the capacitance exhibits a very low voltage coefficient. It has virtually no dielectric absorbtion and has a very low temperature drift coefficient in differential mode (
