TTP223 is a single channel touch detector IC that could be used as a 1 touch key driver. It is a useful interface when replaced with a traditional button key. It has a low power consumption with a wide range of operating voltage. It has an auto calibration feature for life and it has a re-calibration period of about…
The 741 series is a general-purpose operational amplifier that outperforms industry standards such as the LM709. In most cases, they are direct, Exceeded plug-in replacements for the 709C, LM201, MC1439, and 748. Many aspects of the amplifiers make their employment practically foolproof: overload protection on the input and output, no latch-up when the common mode…
