GENERAL DESCRIPTION
voltages, while providing increased performance, dramatically
lower power consumption, and reduced package size.
The ADG1436 is a monolithic CMOS device containing two
independently selectable SPDT switches. An EN input on the
LFCSP package is used to enable or disable the device. When
disabled, all channels are switched off. Each switch conducts
equally well in both directions when on and has an input signal
range that extends to the supplies. In the off condition, signal
levels up to the supplies are blocked. Both switches exhibit
break-before-make switching action for use in multiplexer
applications.
The on resistance profile is very flat over the full analog input
range ensuring excellent linearity and low distortion when
switching audio signals. iCMOS construction ensures ultralow
power dissipation, making the part ideally suited for portable
and battery-powered instruments.
PRODUCT HIGHLIGHTS
1. 2Ω Max On Resistance over temperature.
2. Minimum distortion
It is designed on an iCMOS process. iCMOS (industrial-
CMOS) is a modular manufacturing process combining high
voltage CMOS (complementary metal-oxide semiconductor)
and bipolar technologies. It enables the development of a wide
range of high performance analog ICs capable of 33 V operation
in a footprint that no previous generation of high voltage parts
has been able to achieve. Unlike analog ICs using conventional
CMOS processes, iCMOS components can tolerate high supply
3. 3 V logic-compatible digital inputs: VIH = 2.0 V, VIL = 0.8 V.
4. No VL logic power supply required.
5. Ultralow power dissipation: <0.03 µW.
6. 16-lead TSSOP and 16-lead 4 mm × 4mm LFCSP
packages.
