MAS9285
IC FOR XO TRIMMING
• Very Low Power
• Wide Trimming Range
• Wide Supply Voltage Range
• Very High Level of Integration
• Electrically Trimmable
• Low Cost
DESCRIPTION
MAS9285 is capacitive digital to analog converter
integrated circuit well suited to make initial offset
trimming of the crystal oscillator. The trimming is
FEATURES
• Very small size
• Minimum current draw
• Wide operating temperature range
done by a serial bus and the calibration information
is stored in an internal PROM.
APPLICATIONS
• OCXO
• All Crystal Oscillators
