GENERAL DESCRIPTION
The ADG1421/ADG1422/ADG1423 contain two independent
single-pole/single-throw (SPST) switches. The ADG1421 and
ADG1422 differ only in that the digital control logic is inverted.
The ADG1421 switches are turned on with Logic 1 on the
appropriate control input, and Logic 0 is required for the
ADG1422. The ADG1423 has one switch with digital control
logic similar to that of the ADG1421; the logic is inverted on
the other switch. The ADG1423 exhibits break-before-make
switching action for use in multiplexer applications. 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.
The iCMOS® (industrial CMOS) modular manufacturing process
combines high voltage, complementary metal-oxide semiconductor
(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 other generation of high voltage
parts has achieved. 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. The iCMOS construction ensures
ultralow power dissipation, making the part ideally suited for
portable and battery-powered instruments.
PRODUCT HIGHLIGHTS
1. 2.4 Ω maximum on resistance at 25°C.
2. Minimum distortion.
3. 3 V logic-compatible digital inputs: VINH = 2.0 V, VINL = 0.8 V.
4. No VL logic power supply required.
5. 10-lead MSOP and 10-lead, 3 mm × 3 mm LFCSP packages.
