| Status: | Active |
|---|---|
| Series: | CAP1128 |
| RoHS: | Compliant |
The CAP1128 is a turnkey capacitive touch controller providing a wide variety of button and proximity functionality, and making it easy for designers to add
aesthetically pleasing, low-cost and robust touch interfaces.
The CAP1128 also contains 2 LED drivers that offer full-on / off, variable rate blinking, dimness controls, and breathing. Each of the LED drivers may be linked to one of the sensor inputs to be actuated when a touch is detected. As well, each LED driver may be individually controlled via a host controller.
