Product: XO (Clock Oscillator)
Series: LPO
Oscillator Type: Clock Oscillators - Low Power Oscillator
Series: LPO
Oscillator Type: Clock Oscillators - Low Power Oscillator
• HCMOS Square Wave Output. • Frequency in Hz and KHz range.
• Current consumption µA range.
LPO (Low Power Oscillator), such as 32.768 KHz, provides time base for real-time clocks.
Its low current consumption (only 6.5 µA for model 37LPO) makes it ideal for
battery-operated devices such as data loggers and portable test equipment.
