Product: XO (Clock Oscillator)
Series: LPO
Oscillator Type: Clock Oscillators - Low Power Oscillator |
| Selection Guide - Specifications |
• 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. |
