NOTES:
2. Q = fo/BW, where: fo = Center Frequency, BW = 3dB Bandwidth
3. Ideal Equation: INTOUT (Volts) = [VIN * GIN * GPR * GBPF * 1/Ï * (N/tC(ms) * fQ(kHz)) * GDSE] + VRESET
Where: VIN = input signal amplitude (VP-P)
GIN = External Input Gain; GIN = RF/RIN
GPR = Programmed Gain
GBPF = Gain of Bandpass Filter (2 for Ideal Case at Center)
tINT = Integration Time; tINT = N/fQ
0.318 = 1/Ï
N = Number of Cycles of Input Signal
fQ = Frequency of Input Signal
RF = Feedback Resistor Value
RIN = Signal Input Resistor Value
tC = Programmed Time Constant
GDSE = Gain of DSE Converter (2 for Ideal Case)
VRESET = Integrator Reset Voltage = 0.125V, Typ
