5LPO44-C4-32.768K Datasheet, PDF (1/1 Pages) EUROQUARTZ limited – LOW POWER CONSUMPTION OSCILLATORS

LOW POWER CONSUMPTION OSCILLATORS
LPO 44 SERIES, Model 4
4 pad SMD Package
OUTLINES AND DIMENSIONS
DESCRIPTION
The Euroquartz LPO44 series of low power consumption oscillators are
ideal parts providing the time base signals for real-time clocks. The
oscillators have very low current consumption (as low as 14mA) and are
ideal for battery operated devices such as data logging and portable test
equipment.
FEATURES
· Very low current consumption from 14mA
· Industry-standard SMD package
· Wide frequency range, from 1Hz to 160kHz
· Supply Voltage from 2.0 Volts to 15.0 Volts
· Standard CMOS output
