TCA355集成电路（IC）的传感器电容式触控规格书PDF中文资料

特性 Features

● Lower open-loop current consumption; IS < 1 mA

● Lower output saturation voltage

● The temperature dependence of the switching distance is lower and compensation of the resonant circuit TC (temperature coefficient) is easier

● The sensitivity is higher, so that larger switching distances are possible and coils of a lower quality can be used

● The switching hysteresis remains constant as regards temperature, supply voltage and switching distance

● The TCA 305 even functions without external integrating capacitor. With an external capacitor (or with RC combination) good noise immunity can be achieved

● The outputs are temporarily short-circuit proof (approx. 10 s to 1 min depending on package)

● The outputs are disabled when VS < approx. 4.5 V and are enabled when the oscillator stabilizes (from VS min = 5 V)

● Higher switching frequencies can be obtained

● Miniature package
