Part Details
- Tiny SC70 Package (1.1mm x 2.2mm x 2.4mm)
- High-Performance Electronically Trimmable Capacitance
- Very Simple Digital Interface
- Eliminates the Need for Mechanical Tuning
- Enabling Technology for Low-Cost Production Line Automation

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.
