CTMU peripheral no yɛ analog module a ɛyɛ mmerɛw a wobetumi de adi dwuma de aka ADC ho de asusuw capacitance no pɛpɛɛpɛ. Ɛwɔ current source a ɛkɔ so daa a ɛka ADC channel yi ho sɛnea wɔakyerɛ no. CTMU no de current source a ɛkɔ so daa di dwuma de bu nsakrae a ɛba wɔ capacitance mu ne bere mu nsonsonoe a ɛda nsɛm a esisi ahorow ntam no ho akontaa.
Sɛ wode toto CVD ho a, CTMU ma mmuae ahoɔhare ntɛmntɛm.Efisɛ ɛwɔ mprempren source ranges ahorow pii.Eyi bɛboa ma charge analog channel no akɔ ntɛmntɛm ntɛmntɛm ,ɛnam so ama mmuae bere a capacitive touch sensing system no de ma no atu mpɔn.
CTMU peripherals for capacitive touch sensing aplikeshɔn no de di dwuma denam Formula I × T=C × V. Wɔn mu: I ne mprempren mprempren fibea a CTMU, t yɛ bere a wɔahyɛ da ayɛ CTMU charging capacitive touch sensor, C yɛ capacitance of capacitive touch, na v is the voltage of the voltage (read).
