The ADG1414 is a monolithic complementary metal-oxide The ADG1414 uses a versatile 3-wire serial interface that semiconductor (CMOS) device containing eight independently operates at clock rates of up to 50 MHz and is compatible with selectable switches designed on an industrial CMOS (iCMOS®) standard SPI, QSPI™, MICROWIRE™, and DSP interface process. iCMOS is a modular manufacturing process combining standards. The output of the shift register, SDO, enables a high voltage CMOS and bipolar technologies. iCMOS components number of these devices to be daisy chained. can tolerate high supply voltages while providing increased perfor- At power-up, all switches are in the off condition, and the mance, dramatically lower power consumption, and reduce the internal registers contain all zeros. package size.
PRODUCT HIGHLIGHTS
The ADG1414 is a set of octal, single-pole, single-throw (SPST) switches controlled via a 3-wire serial interface. On resistance is 1. 50 MHz serial interface. matched closely between switches and is very flat over the full 2. 9.5 Ω on resistance. signal range. Each switch conducts equally well in both directions 3. 1.6 Ω on-resistance flatness. and the input signal range extends to the supplies. 4. 24-lead TSSOP and 4 mm × 4 mm LFCSP packages. Data is written to these devices in the form of eight bits; each bit corresponds to one channel.
