FMA1125DC - Touch Sensor Controller

Features

  • of the FMA1125DC is APIS™ (Adjacent Pattern Interference Suppression). APIS is a filtering function that eliminates adjacent key or pattern interference. The FMA1125DC also gives touch-strength output in addition to touch on/off output. There are a number of DIOs depending on the package type that can be configured and programmed to meet specific requirements, giving customers greater flexibility and value. The FMA1125DC comes with various package types to support different numbers of input chan.

    FMA1125DC Overview Touch Sensor Controller The FMA1125DC is a low-power, compact, flexible touch sensor controller that converts capacitance generated between the human body and a conductive touch pad to digital data without any analog signal processing. Its programmability provides design flexibility, high performance and stability for a broad range of applications. The FMA1125DC’s AIC™ (Automatic Impedance Calibration) function can be easily configured to support different sensitivities for individual channels independently as well as to change values of parameters such as the calibration interval. AICTM may also be temporarily paused and resumed by a host MCU. Among the many features of the FMA1125DC is APIS™ (Adjacent Pattern Interference Suppression).
