MAX1474AXT-T中文资料美信数据手册PDF规格书

General Description

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 (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 (
