Folks:

anyone able to find the nearest compatible TI capacitance to digital convertor

to this obsolete part QT300 ? Still want an I2C interface - thanks!

Hi Jim,

Please check out FDC1004, which is based on charge-transfer. We also have a second-generation device FDC2212/4, which is based on LC resonator and has better noise performance.

Yibo
