STLC7550  
Pins description & Block diagram  
than two times the sampling frequency (FS), so that the combined frequency response of  
both the internal and external filters is flat in the passband. The attenuator of the last output  
stage can be programmed to 0dB, 6dB or infinite.  
Non-inverting Analog Input (IN+)  
This pin is the differential non-inverting ADC input.  
Inverting Analog Input (IN-)  
This pin is the differential inverting ADC input. These analog inputs (IN+, IN-) are presented  
to the Sigma-Delta modulator. The analog input peak-topeak differential signal range must  
be less than 2 x V , and must be preceded by an external single pole anti-aliasing filter.  
REF  
The cut-off frequency of the filter must be lower than one half the oversampling frequency.  
These filters should be set as close as possible to the IN+ and IN- pins. The gain of the first  
stage is programmable (see Table 4).  
Non-inverting Auxiliary Analog Input (AUX IN+)  
This pin is the differential non-inverting auxiliary ADC input. The characteristics are same as  
the IN+ input.  
Inverting Auxiliary Analog Input (AUX IN-)  
This pin is the differential inverting auxiliary ADC input. The characteristics are same as the  
IN- input. The input pair (IN+/IN- or AUX IN+/AUX IN-) are software selectable.
