The ADG1433 and ADG1434 are monolithic industrial CMOS
S2B S3B
(iCMOS®) analog switches comprising three independently
D2 D3
selectable single-pole, double-throw (SPDT) switches and
S2A S3A
four independently selectable SPDT switches, respectively. 2 All channels exhibit break-before-make switching action that 00

18 prevents momentary shorting when switching channels. An EN 06 Figure 2. ADG1434 TSSOP input on the ADG1433 (LFCSP and TSSOP) and ADG1434 (LFCSP only) enables or disables the device. When disabled, all
ADG1434
channels are switched off.
S1A S4A D1 D4
The iCMOS modular manufacturing process combines high
S1B S4B
voltage, complementary metal-oxide semiconductor (CMOS), and bipolar technologies. It enables the development of a wide
S2B S3B
range of high performance analog ICs capable of 33 V operation
D2 D3
in a footprint that no other generation of high voltage devices
S2A S3A
has been able to achieve. Unlike analog ICs using a conventional
LOGIC
CMOS process, iCMOS components can tolerate high supply voltages while providing increased performance, dramatically lower power consumption, and reduced package size.
