Applications Discussion
The standard connections for the DEI3283 are shown in the figure below. Dual ±15VDC supplies are recommended for the +VS/-VS
supplies. Decoupling of all supplies should be done near the IC to avoid propagation of noise spikes due to switching transients. The
ground connection should be sturdy and isolated from large switching currents to provide as quiet a ground reference as possible. The
noise filter capacitors are optional and are added to provide extra noise immunity by limiting bandwidth of the input signal before it
reaches the window comparator stage. Two capacitors are used for each channel and they must be the same value. The suggested
capacitor value for a 100 kHz operation is 39 pF. For lower data rates, larger values of capacitance may be used to yield better noise
performance. To get optimum performance, the following equation can be used to calculate capacitor value for a specific data rate:
Where CFILTER is the capacitor value in pF, and FO is the input frequency (10 kHz dꢀFO dꢀ150 kHz).
