Product Description

The GFO-3301 32.768kHz oscillator solution uses a tuning fork resonator to produce CMOS output whilst consuming very low supply current of only 1.5µA. This miniature oscillator also features very low standby current consumption of only 1.0µA.

The GFO-3301 also features -40 to +85°C operating temperature range and enable/disable tristate functionality as standard. 

If you need a 32.768kHz oscillator solution with tighter temperature stability please consider the GAO-3301.
