DS3231SN clock IC SOP16 package

the DS3231SN clock IC is a highly accurate i2c clock with a temperature-compensated crystal oscillator (tcxo). this chip has a battery input and maintains precise timing when the main power supply is interrupted. the integration feature of the crystal resonator enhances the long-term accuracy of the ic. the ds3231 is available in both commercial and industrial temperature ranges and is provided in a 16-pin sop16 package.
