MAX1474 Miniature Electronically Trimmable Capacitor

The MAX1474 is a fine-line (geometry) electronically trimmable capacitor (FLECAP) programmable through a simple digital Interface There are 32 programmable capacitance values ranging from 6.4pF to 13.3pF in 0.22pF increments (see Table 1). The quartz dielectric capacitance is highly stable and exhibits a very low voltage coefficient. It has virtually no dielectric absorption and has a very low temperature drift coefficient (<33ppm/C). The MAX1474 is programmed through two digital Interface pins, which have Schmidt triggers and pulldown resistors to secure capacitance programming.
