sampling frequency for the digital filter, f(s), oscillator
An external resistor (RT) and capacitor (CT) must be connected from the respective RT and CT terminals to
GND to set the sampling frequency for the digital filter. Charge/discharge current at terminal CT will nominally
be
±2 × (1V/RT). Nominal period is determined by the formula: T(CT) = 2 × RT × CT (see Figure 5).
