The ADG1414 is a set of octal, single-pole, single-throw (SPST) switches controlled via a 3-wire serial interface. On resistance is matched closely between switches and is very flat over the full signal range. Each switch conducts equally well in both directions and the input signal range extends to the supplies. Data is written to these devices in the form of eight bits; each bit corresponds to one channel. FUNCTIONAL BLOCK DIAGRAM ADG1414 S1 D1 S2 D2 S3 D3 S4 D4 S5 D5 S6 D6 S...
