GENERAL DESCRIPTION
The ADG1404 is a complementary metal-oxide semiconductor
(CMOS) analog multiplexer, comprising four single channels
designed on an iCMOS® process. iCMOS (industrial CMOS) is
a modular manufacturing process that combines high voltage
CMOS 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 devices achieve. Unlike analog ICs using conventional
CMOS processes, iCMOS components can tolerate high supply
voltages while providing increased performance, dramatically
lower power consumption, and reduced package size.
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 device ideally suited for portable and battery-
powered instruments.
The ADG1404 switches one of four inputs to a common output,
D, as determined by the 3-bit binary address lines, A0, A1, and
EN. Logic 0 on the EN pin disables the device. Each switch
conducts equally well in both directions when on and has an
input signal range that extends to the supplies. In the off condi-
tion, signal levels up to the supplies are blocked. All switches
exhibit break-before-make switching action. Inherent in the
design is low charge injection for minimum transients when
switching the digital inputs.
PRODUCT HIGHLIGHTS
1. 2.6 Ω maximum on resistance over temperature.
2. Minimum distortion.
3. Ultralow power dissipation: <0.03 μW.
4. 14-lead TSSOP and 16-lead, 4 mm × 4 mm LFCSP package.
