DESCRIPTION
MAS9285 is capacitive digital to analog converter
integrated circuit well suited to make initial offset
trimming of the crystal oscillator. The trimming is
done by a serial bus and the calibration information
is stored in an internal PROM.

Note
Note: Because the substrate of the die is internally connected to VDD, the die has to be connected to VDD or
left floating. Please make sure that VDD is the first pad to be bonded. Pick-and-place and all component
assembly are recommended to be performed in ESD protected area.
Note: Pad coordinates measured from the left bottom corner of the chip to the center of the pads. The
coordinates may vary depending on sawing width and location, however, distances between pads are accurate.
