MTCH108
MTCH108 is Proximity/Touch Controller manufactured by Microchip Technology.
- Part of the MTCH102 comparator family.
- Part of the MTCH102 comparator family.
Description
The Microchip m Touch® MTCH102/5/8 Proximity/Touch Controller with simple digital output provides an easy way to add proximity or touch detection to any application. This device family implements capacitive sensors with active guarding capability. The sensitivity and power mode can be configured through the MTSA and MTPM pins. The MTCH102/5/8 devices also use an advanced optimization algorithm to actively suppress noise from the signal to achieve reliable proximity/touch detection.
