The use of Cin is not mandatory, and is not recommended where the lines to be protected are used for output or for both input and output. For digital input lines, the use of a small capacitor in the range of 50 pF to 220 pF is recommended as this will reduce the rate of rise of voltage seen by the TCF6000 and hence the possibility of overshoot. In the case of the analog inputs, such as that from the pressure sensor, the capacitor Cin is necessary for devices such as the MC6805S2 shown, which present a low impedance during the sampling period. The maximum value for Cin is determined by the accuracy required, the time taken to sample the input and the input impedance during that time, while the maximum value is determined by the required frequency response and the value of Rin. Thus for a resistive input A/D connector where: Ts R D Vin k Q 1 Q 2 ID = Sample time (seconds) = Device input resistance (Ω ) = Input voltage (V) = Required accuracy (%) = Charge on capacitor before sampling = Charge on capacitor after sampling = Device input current (A) Q 1–Q 2 = k/C0002Q 1 100 Thus: but, and, Q 1 Q 1–Q 2 = Cin Vin = ID • Ts so that, ID Ts =k • C in–Vin 100 and, Cin (min) =ID • Ts Vin• k Farad so, Cin (min) =100 • Ts k • R D Farad The calculation for a sample and hold type converter is even simpler: k C H = Required accuracy (%) = Hold capacitor (Farad) C in (min) =100 • C H k Farad For the MC6805S2 this comes out at: C in (min) =100.25 pF 0.25 = 10 nF for 1/4% accuracy
