ANALOG INPUTS Each ADC in the AD7366-5/AD7367-5 has two single-ended analog inputs. Figure 18 shows the equivalent circuit of the analog input structure of the AD7366-5/AD7367-5. The two diodes provide ESD protection. Care must be taken to ensure that the ...
Page 18
AD7366-5/AD7367-5 Unlike other bipolar ADCs, the AD7366-5/AD7367-5 do not have a resistive analog input structure. On the AD7366-5/ AD7366-5, the bipolar analog signal is sampled directly onto the sampling capacitor. This gives the devices high analog input impedance. The analog ...

AD7366-5/AD7367-5 MODES OF OPERATION The mode of operation for the AD7366-5/AD7367-5 is selected by the (logic) state of the CNVST signal at the end of a conver- sion. There are two possible modes of operation: normal mode and shutdown mode. ...
Page 21
SHUTDOWN MODE Shutdown mode is intended for use in applications where slow throughput rates are required. Shutdown mode is suited to applications where a series of conversions performed at a relatively high throughput rate are followed by a long period ...
