The AT42QT1070 (QT1070) is a digital burst mode charge-transfer (QT ™ ) capacitive sensor driver. The device can sense from one to seven keys, dependent on mode. The QT1070 includes all signal processing func tions necessary to provide stable sensing under a wide variety of changing conditions, and the outputs are fully debounced. Only a few external parts are required for operation and no external Cs capacitors are required. The QT1070 modulates its bursts in a spread-spectrum fashion in order to heavily suppress the effects of external noise, and to suppress RF emissions. The QT1070 use a dual-pulse method of acquisition. This provides greater noise immunity and eliminates the need for external sampling capacitors, allowing touch sensing using a single pin. https://elecena.pl/product/9695339/at42qt1070-ssu-7-channel-touch-sensor-qtouch-so-14 2017-08-05 https://elecena.pl/product/9695339/at42qt1070-ssu-7-channel-touch-sensor-qtouch-so-14 2018-05-05 https://elecena.pl/product/9695339/at42qt1070-ssu-7-channel-touch-sensor-qtouch-so-14 2018-12-16 https://elecena.pl/product/9695339/at42qt1070-ssu-7-channel-touch-sensor-qtouch-so-14 2019-04-02 https://elecena.pl/product/9695339/at42qt1070-ssu-7-channel-touch-sensor-qtouch-so-14 2021-05-01 https://elecena.pl/product/9695339/at42qt1070-ssu-7-channel-touch-sensor-qtouch-so-14 2021-05-26 https://elecena.pl/product/9695339/at42qt1070-ssu-7-channel-touch-sensor-qtouch-so-14 2022-05-22 https://elecena.pl/product/9695339/at42qt1070-ssu-7-channel-touch-sensor-qtouch-so-14 2022-10-21 https://elecena.pl/product/9695339/at42qt1070-ssu-7-channel-touch-sensor-qtouch-so-14 2023-01-07 https://elecena.pl/product/9695339/at42qt1070-ssu-7-channel-touch-sensor-qtouch-so-14 2023-09-03 https://elecena.pl/product/9695339/at42qt1070-ssu-7-channel-touch-sensor-qtouch-so-14 2025-12-12 https://elecena.pl/product/9695339/at42qt1070-ssu-7-channel-touch-sensor-qtouch-so-14 2026-01-18 https://elecena.pl/product/9695339/at42qt1070-ssu-7-channel-touch-sensor-qtouch-so-14 2026-02-13
