GENERAL DESCRIPTION
The ADG1414 is a monolithic complementary metal-oxide
semiconductor (CMOS) device containing eight independently
selectable switches designed on an industrial CMOS (iCMOS®)
process. iCMOS is a modular manufacturing process combining
high voltage CMOS and bipolar technologies. iCMOS components
can tolerate high supply voltages while providing increased perfor-
mance, dramatically lower power consumption, and reduce the
package size.
The ADG1414 utilizes a versatile 3-wire serial interface that
operates at clock rates of up to 50 MHz and is compatible with
standard SPI, QSPI™, MICROWIRE™, and DSP interface
standards. The output of the shift register, SDO, enables a
number of these parts to be daisy chained.
On power-up, all switches are in the off condition, and the
internal registers contain all zeros.
The ADG1414 is a set of octal SPST (single-pole, single-throw)
switches controlled via a 3-wire serial interface. On resistance is
closely matched between switches and is very flat over the full
signal range. Each switch conducts equally well in both direc-
tions and the input signal range extends to the supplies.
