The MAX1474 is a fine-line (geometry) electronically trim-
mable 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 (Table 1). The quartz dielectric
capacitance is highly stable and exhibits a very low volt-
age 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.
